- | Statistic | Data Type | Description |
- +==============================================+================+====================================+
- | pkt4-received | integer | Number of DHCPv4 packets received. |
- | | | This includes all packets: valid, |
- | | | bogus, corrupted, rejected, etc. |
- | | | This statistic is expected to grow |
- | | | rapidly. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-discover-received | integer | Number of DHCPDISCOVER packets |
- | | | received. This statistic is |
- | | | expected to grow; its increase |
- | | | means that clients that just |
- | | | booted started their configuration |
- | | | process and their initial packets |
- | | | reached the Kea server. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-offer-received | integer | Number of DHCPOFFER packets |
- | | | received. This statistic is |
- | | | expected to remain zero at all |
- | | | times, as DHCPOFFER packets are |
- | | | sent by the server and the server |
- | | | is never expected to receive them. |
- | | | A non-zero value indicates an |
- | | | error. One likely cause would be a |
- | | | misbehaving relay agent that |
- | | | incorrectly forwards DHCPOFFER |
- | | | messages towards the server, |
- | | | rather than back to the clients. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-request-received | integer | Number of DHCPREQUEST packets |
- | | | received. This statistic is |
- | | | expected to grow. Its increase |
- | | | means that clients that just |
- | | | booted received the server's |
- | | | response (DHCPOFFER) and accepted |
- | | | it, and are now requesting an |
- | | | address (DHCPREQUEST). |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-ack-received | integer | Number of DHCPACK packets |
- | | | received. This statistic is |
- | | | expected to remain zero at all |
- | | | times, as DHCPACK packets are sent |
- | | | by the server and the server is |
- | | | never expected to receive them. A |
- | | | non-zero value indicates an error. |
- | | | One likely cause would be a |
- | | | misbehaving relay agent that |
- | | | incorrectly forwards DHCPACK |
- | | | messages towards the server, |
- | | | rather than back to the clients. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-nak-received | integer | Number of DHCPNAK packets |
- | | | received. This statistic is |
- | | | expected to remain zero at all |
- | | | times, as DHCPNAK packets are sent |
- | | | by the server and the server is |
- | | | never expected to receive them. A |
- | | | non-zero value indicates an error. |
- | | | One likely cause would be a |
- | | | misbehaving relay agent that |
- | | | incorrectly forwards DHCPNAK |
- | | | messages towards the server, |
- | | | rather than back to the clients. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-release-received | integer | Number of DHCPRELEASE packets |
- | | | received. This statistic is |
- | | | expected to grow. Its increase |
- | | | means that clients that had an |
- | | | address are shutting down or |
- | | | ceasing to use their addresses. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-decline-received | integer | Number of DHCPDECLINE packets |
- | | | received. This statistic is |
- | | | expected to remain close to zero. |
- | | | Its increase means that a client |
- | | | leased an address, but discovered |
- | | | that the address is currently |
- | | | used by an unknown device |
- | | | elsewhere in the network. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-inform-received | integer | Number of DHCPINFORM packets |
- | | | received. This statistic is |
- | | | expected to grow. Its increase |
- | | | means that there are clients |
- | | | that either do not need an address |
- | | | or already have an address and are |
- | | | interested only in getting |
- | | | additional configuration |
- | | | parameters. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-unknown-received | integer | Number of packets received of an |
- | | | unknown type. A non-zero value of |
- | | | this statistic indicates that the |
- | | | server received a packet that it |
- | | | was not able to recognize, either |
- | | | with an unsupported type or |
- | | | possibly malformed (without a |
- | | | message-type option). |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-sent | integer | Number of DHCPv4 packets sent. |
- | | | This statistic is expected to grow |
- | | | every time the server transmits a |
- | | | packet. In general, it should |
- | | | roughly match pkt4-received, as |
- | | | most incoming packets cause the |
- | | | server to respond. There are |
- | | | exceptions (e.g. DHCPRELEASE), so |
- | | | do not worry if it is less than |
- | | | pkt4-received. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-offer-sent | integer | Number of DHCPOFFER packets sent. |
- | | | This statistic is expected to grow |
- | | | in most cases after a DHCPDISCOVER |
- | | | is processed. There are certain |
- | | | uncommon, but valid, cases where |
- | | | incoming DHCPDISCOVER packets are |
- | | | dropped, but in general this |
- | | | statistic is expected to be close |
- | | | to pkt4-discover-received. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-ack-sent | integer | Number of DHCPACK packets sent. |
- | | | This statistic is expected to grow |
- | | | in most cases after a DHCPREQUEST |
- | | | is processed. There are certain |
- | | | cases where DHCPNAK is sent |
- | | | instead. In general, the sum of |
- | | | pkt4-ack-sent and pkt4-nak-sent |
- | | | should be close to |
- | | | pkt4-request-received. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-nak-sent | integer | Number of DHCPNAK packets sent. |
- | | | This statistic is expected to grow |
- | | | when the server chooses not to |
- | | | honor the address requested by a |
- | | | client. In general, the sum of |
- | | | pkt4-ack-sent and pkt4-nak-sent |
- | | | should be close to |
- | | | pkt4-request-received. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-parse-failed | integer | Number of incoming packets that |
- | | | could not be parsed. A non-zero |
- | | | value of this statistic indicates |
- | | | that the server received a |
- | | | malformed or truncated packet. |
- | | | This may indicate problems in the |
- | | | network, faulty clients, or a bug |
- | | | in the server. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt4-receive-drop | integer | Number of incoming packets that |
- | | | were dropped. The exact reason for |
- | | | dropping packets is logged, but |
- | | | the most common reasons may be: an |
- | | | unacceptable packet type was |
- | | | received, direct responses are |
- | | | forbidden, or the server-id sent |
- | | | by the client does not match the |
- | | | server's server-id. |
- +----------------------------------------------+----------------+------------------------------------+
- | subnet[id].total-addresses | integer | Total number of addresses |
- | | | available for DHCPv4 management; |
- | | | in other words, this is the sum of |
- | | | all addresses in all configured |
- | | | pools. This statistic changes only |
- | | | during configuration updates. It |
- | | | does not take into account any |
- | | | addresses that may be reserved due |
- | | | to host reservation. The *id* is |
- | | | the subnet-id of a given subnet. |
- | | | This statistic is exposed for each |
- | | | subnet separately, and is reset |
- | | | during a reconfiguration event. |
- +----------------------------------------------+----------------+------------------------------------+
- | cumulative-assigned-addresses | integer | Cumulative number of addresses |
- | | | that have been assigned since |
- | | | server startup. It is incremented |
- | | | each time an address is assigned |
- | | | and is not reset when the server |
- | | | is reconfigured. |
- +----------------------------------------------+----------------+------------------------------------+
- | subnet[id].cumulative-assigned-addresses | integer | Cumulative number of assigned |
- | | | addresses in a given subnet. It |
- | | | increases every time a new lease |
- | | | is allocated (as a result of |
- | | | receiving a DHCPREQUEST message) |
- | | | and never decreases. The *id* is |
- | | | the subnet-id of the subnet. This |

- | | | subnet separately, and is reset |
- | | | during a reconfiguration event. |
- +----------------------------------------------+----------------+------------------------------------+
- | subnet[id].assigned-addresses | integer | Number of assigned addresses in a |
- | | | given subnet. It increases every |
- | | | time a new lease is allocated (as |
- | | | a result of receiving a |
- | | | DHCPREQUEST message) and decreases |
- | | | every time a lease is released (a |
- | | | DHCPRELEASE message is received) |
- | | | or expires. The *id* is the |
- | | | subnet-id of the subnet. This |
- | | | statistic is exposed for each |
- | | | subnet separately, and is reset |
- | | | during a reconfiguration event. |
- +----------------------------------------------+----------------+------------------------------------+
- | reclaimed-leases | integer | Number of expired leases that have |
- | | | been reclaimed since server |
- | | | startup. It is incremented each |
- | | | time an expired lease is reclaimed |
- | | | and never decreases. It can be |
- | | | used as a long-term indicator of |
- | | | how many actual leases have been |
- | | | reclaimed. This is a global |
- | | | statistic that covers all subnets. |
- +----------------------------------------------+----------------+------------------------------------+
- | subnet[id].reclaimed-leases | integer | Number of expired leases |
- | | | associated with a given subnet |
- | | | (*id* is the subnet-id) that have |
- | | | been reclaimed since server |
- | | | startup. It is incremented each |
- | | | time an expired lease is |
- | | | reclaimed. The *id* is the |
- | | | subnet-id of a given subnet. This |
- | | | statistic is exposed for each |
- | | | subnet separately. |
- +----------------------------------------------+----------------+------------------------------------+
- | declined-addresses | integer | Number of IPv4 addresses that are |
- | | | currently declined; a count of the |
- | | | number of leases currently |
- | | | unavailable. Once a lease is |
- | | | recovered, this statistic is |
- | | | decreased; ideally, this statistic |
- | | | should be zero. If this statistic |
- | | | is non-zero or increasing, a |
- | | | network administrator should |
- | | | investigate whether there is a |
- | | | misbehaving device in the network. |
- | | | This is a global statistic that |
- | | | covers all subnets. |
- +----------------------------------------------+----------------+------------------------------------+
- | subnet[id].declined-addresses | integer | Number of IPv4 addresses that are |
- | | | currently declined in a given |
- | | | subnet; a count of the number of |
- | | | leases currently unavailable. Once |
- | | | a lease is recovered, this |
- | | | statistic is decreased; ideally, |
- | | | this statistic should be zero. If |
- | | | this statistic is non-zero or |
- | | | increasing, a network |

- +----------------------------------------------+----------------+------------------------------------+
- | reclaimed-declined-addresses | integer | Number of IPv4 addresses that were |
- | | | declined, but have now been |
- | | | recovered. Unlike |
- | | | declined-addresses, this statistic |

+ +----------------------------------------------------+----------------+------------------------------------+
+ | pkt4-parse-failed | integer | Number of incoming packets that |

+ | | | in the server. |
+ +----------------------------------------------------+----------------+------------------------------------+
+ | pkt4-receive-drop | integer | Number of incoming packets that |
+ | | | were dropped. The exact reason for |
+ | | | dropping packets is logged, but |
+ | | | the most common reasons may be: an |
+ | | | unacceptable packet type was |

- | Statistic | Data Type | Description |
- +==============================================+================+====================================+
- | pkt6-received | integer | Number of DHCPv6 packets received. |
- | | | This includes all packets: valid, |
- | | | bogus, corrupted, rejected, etc. |
- | | | This statistic is expected to grow |
- | | | rapidly. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-receive-drop | integer | Number of incoming packets that |
- | | | were dropped. The exact reason for |
- | | | dropping packets is logged, but |
- | | | the most common reasons may be: an |
- | | | unacceptable or not supported |
- | | | packet type is received, direct |
- | | | responses are forbidden, the |
- | | | server-id sent by the client does |
- | | | not match the server's server-id, |
- | | | or the packet is malformed. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-parse-failed | integer | Number of incoming packets that |
- | | | could not be parsed. A non-zero |
- | | | value of this statistic indicates |
- | | | that the server received a |
- | | | malformed or truncated packet. |
- | | | This may indicate problems in the |
- | | | network, faulty clients, faulty |
- | | | relay agents, or a bug in the |
- | | | server. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-solicit-received | integer | Number of SOLICIT packets |
- | | | received. This statistic is |
- | | | expected to grow; its increase |
- | | | means that clients that just |
- | | | booted started their configuration |
- | | | process and their initial packets |
- | | | reached the Kea server. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-advertise-received | integer | Number of ADVERTISE packets |
- | | | received. ADVERTISE packets are |
- | | | sent by the server and the server |
- | | | is never expected to receive them. |
- | | | A non-zero value of this statistic |
- | | | indicates an error occurring in |
- | | | the network. One likely cause |
- | | | would be a misbehaving relay |
- | | | agent that incorrectly forwards |
- | | | ADVERTISE messages towards the |
- | | | server, rather than back to the |
- | | | clients. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-request-received | integer | Number of DHCPREQUEST packets |
- | | | received. This statistic is |
- | | | expected to grow. Its increase |
- | | | means that clients that just |
- | | | booted received the server's |
- | | | response (DHCPADVERTISE) and |
- | | | accepted it, and are now |
- | | | requesting an address |
- | | | (DHCPREQUEST). |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-reply-received | integer | Number of REPLY packets received. |
- | | | This statistic is expected to |
- | | | remain zero at all times, as REPLY |
- | | | packets are sent by the server and |
- | | | the server is never expected to |
- | | | receive them. A non-zero value |
- | | | indicates an error. One likely |
- | | | cause would be a misbehaving relay |
- | | | agent that incorrectly forwards |
- | | | REPLY messages towards the server, |
- | | | rather than back to the clients. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-renew-received | integer | Number of RENEW packets received. |
- | | | This statistic is expected to |
- | | | grow; its increase means that |
- | | | clients received their addresses |
- | | | and prefixes and are trying to |
- | | | renew them. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-rebind-received | integer | Number of REBIND packets received. |
- | | | A non-zero value indicates that |
- | | | clients did not receive responses |
- | | | to their RENEW messages (through |
- | | | the regular lease-renewal |
- | | | mechanism) and are attempting to |
- | | | find any server that is able to |
- | | | take over their leases. It may |
- | | | mean that some servers' REPLY |
- | | | messages never reached the |
- | | | clients. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-release-received | integer | Number of RELEASE packets |
- | | | received. This statistic is |
- | | | expected to grow when a device is |
- | | | being shut down in the network; it |
- | | | indicates that the address or |
- | | | prefix assigned is reported as no |
- | | | longer needed. Note that many |
- | | | devices, especially wireless, do |
- | | | not send RELEASE packets either |
- | | | because of design choice or due to |
- | | | the client moving out of range. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-decline-received | integer | Number of DECLINE packets |
- | | | received. This statistic is |
- | | | expected to remain close to zero. |
- | | | Its increase means that a client |
- | | | leased an address, but discovered |
- | | | that the address is currently used |
- | | | by an unknown device in the |
- | | | network. If this statistic is |
- | | | growing, it may indicate a |
- | | | misconfigured server or devices |
- | | | that have statically assigned |
- | | | conflicting addresses. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-infrequest-received | integer | Number of INFORMATION-REQUEST |
- | | | packets received. This statistic |
- | | | is expected to grow if there are |
- | | | devices that are using stateless |
- | | | DHCPv6. INFORMATION-REQUEST |
- | | | messages are used by clients that |
- | | | request stateless configuration, |
- | | | i.e. options and parameters other |
- | | | than addresses or prefixes. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-dhcpv4-query-received | integer | Number of DHCPv4-QUERY packets |
- | | | received. This statistic is |
- | | | expected to grow if there are |
- | | | devices that are using |
- | | | DHCPv4-over-DHCPv6. DHCPv4-QUERY |
- | | | messages are used by DHCPv4 |
- | | | clients on an IPv6-only line which |
- | | | encapsulates the requests over |
- | | | DHCPv6. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-dhcpv4-response-received | integer | Number of DHCPv4-RESPONSE packets |
- | | | received. This statistic is |
- | | | expected to remain zero at all |
- | | | times, as DHCPv4-RESPONSE packets |
- | | | are sent by the server and the |
- | | | server is never expected to |
- | | | receive them. A non-zero value |
- | | | indicates an error. One likely |
- | | | cause would be a misbehaving relay |
- | | | agent that incorrectly forwards |
- | | | DHCPv4-RESPONSE message towards |
- | | | the server rather than back to the |
- | | | clients. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-unknown-received | integer | Number of packets received of an |
- | | | unknown type. A non-zero value of |
- | | | this statistic indicates that the |
- | | | server received a packet that it |
- | | | was unable to recognize; either it |
- | | | had an unsupported type or was |
- | | | possibly malformed. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-sent | integer | Number of DHCPv6 packets sent. |
- | | | This statistic is expected to grow |
- | | | every time the server transmits a |
- | | | packet. In general, it should |
- | | | roughly match pkt6-received, as |
- | | | most incoming packets cause the |
- | | | server to respond. There are |
- | | | exceptions (e.g. server receiving |
- | | | a REQUEST with server-id matching |
- | | | another server), so do not worry |
- | | | if it is less than pkt6-received. |
- +----------------------------------------------+----------------+------------------------------------+
- | pkt6-advertise-sent | integer | Number of ADVERTISE packets sent. |
- | | | This statistic is expected to grow |
- | | | in most cases after a SOLICIT is |
- | | | processed. There are certain |
- | | | uncommon, but valid, cases where |
- | | | incoming SOLICIT packets are |
- | | | dropped, but in general this |
- | | | statistic is expected to be close |
- | | | to pkt6-solicit-received. |

+ | Statistic | Data Type | Description |
+ +===================================================+================+====================================+
+ | pkt6-received | integer | Number of DHCPv6 packets received. |
+ | | | This includes all packets: valid, |
+ | | | bogus, corrupted, rejected, etc. |
+ | | | This statistic is expected to grow |
+ | | | rapidly. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-receive-drop | integer | Number of incoming packets that |
+ | | | were dropped. The exact reason for |
+ | | | dropping packets is logged, but |
+ | | | the most common reasons may be: an |
+ | | | unacceptable or not supported |
+ | | | packet type is received, direct |
+ | | | responses are forbidden, the |
+ | | | server-id sent by the client does |
+ | | | not match the server's server-id, |
+ | | | or the packet is malformed. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-parse-failed | integer | Number of incoming packets that |
+ | | | could not be parsed. A non-zero |
+ | | | value of this statistic indicates |
+ | | | that the server received a |
+ | | | malformed or truncated packet. |
+ | | | This may indicate problems in the |
+ | | | network, faulty clients, faulty |
+ | | | relay agents, or a bug in the |
+ | | | server. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-solicit-received | integer | Number of SOLICIT packets |
+ | | | received. This statistic is |
+ | | | expected to grow; its increase |
+ | | | means that clients that just |
+ | | | booted started their configuration |
+ | | | process and their initial packets |
+ | | | reached the Kea server. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-advertise-received | integer | Number of ADVERTISE packets |
+ | | | received. ADVERTISE packets are |
+ | | | sent by the server and the server |
+ | | | is never expected to receive them. |
+ | | | A non-zero value of this statistic |
+ | | | indicates an error occurring in |
+ | | | the network. One likely cause |
+ | | | would be a misbehaving relay |
+ | | | agent that incorrectly forwards |
+ | | | ADVERTISE messages towards the |
+ | | | server, rather than back to the |
+ | | | clients. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-request-received | integer | Number of DHCPREQUEST packets |
+ | | | received. This statistic is |
+ | | | expected to grow. Its increase |
+ | | | means that clients that just |
+ | | | booted received the server's |
+ | | | response (DHCPADVERTISE) and |
+ | | | accepted it, and are now |
+ | | | requesting an address |
+ | | | (DHCPREQUEST). |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-reply-received | integer | Number of REPLY packets received. |
+ | | | This statistic is expected to |
+ | | | remain zero at all times, as REPLY |
+ | | | packets are sent by the server and |
+ | | | the server is never expected to |
+ | | | receive them. A non-zero value |
+ | | | indicates an error. One likely |
+ | | | cause would be a misbehaving relay |
+ | | | agent that incorrectly forwards |
+ | | | REPLY messages towards the server, |
+ | | | rather than back to the clients. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-renew-received | integer | Number of RENEW packets received. |
+ | | | This statistic is expected to |
+ | | | grow; its increase means that |
+ | | | clients received their addresses |
+ | | | and prefixes and are trying to |
+ | | | renew them. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-rebind-received | integer | Number of REBIND packets received. |
+ | | | A non-zero value indicates that |
+ | | | clients did not receive responses |
+ | | | to their RENEW messages (through |
+ | | | the regular lease-renewal |
+ | | | mechanism) and are attempting to |
+ | | | find any server that is able to |
+ | | | take over their leases. It may |
+ | | | mean that some servers' REPLY |
+ | | | messages never reached the |
+ | | | clients. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-release-received | integer | Number of RELEASE packets |
+ | | | received. This statistic is |
+ | | | expected to grow when a device is |
+ | | | being shut down in the network; it |
+ | | | indicates that the address or |
+ | | | prefix assigned is reported as no |
+ | | | longer needed. Note that many |
+ | | | devices, especially wireless, do |
+ | | | not send RELEASE packets either |
+ | | | because of design choice or due to |
+ | | | the client moving out of range. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-decline-received | integer | Number of DECLINE packets |
+ | | | received. This statistic is |
+ | | | expected to remain close to zero. |
+ | | | Its increase means that a client |
+ | | | leased an address, but discovered |
+ | | | that the address is currently used |
+ | | | by an unknown device in the |
+ | | | network. If this statistic is |
+ | | | growing, it may indicate a |
+ | | | misconfigured server or devices |
+ | | | that have statically assigned |
+ | | | conflicting addresses. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-infrequest-received | integer | Number of INFORMATION-REQUEST |
+ | | | packets received. This statistic |
+ | | | is expected to grow if there are |
+ | | | devices that are using stateless |
+ | | | DHCPv6. INFORMATION-REQUEST |
+ | | | messages are used by clients that |
+ | | | request stateless configuration, |
+ | | | i.e. options and parameters other |
+ | | | than addresses or prefixes. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-dhcpv4-query-received | integer | Number of DHCPv4-QUERY packets |
+ | | | received. This statistic is |
+ | | | expected to grow if there are |
+ | | | devices that are using |
+ | | | DHCPv4-over-DHCPv6. DHCPv4-QUERY |
+ | | | messages are used by DHCPv4 |
+ | | | clients on an IPv6-only line which |
+ | | | encapsulates the requests over |
+ | | | DHCPv6. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-dhcpv4-response-received | integer | Number of DHCPv4-RESPONSE packets |
+ | | | received. This statistic is |
+ | | | expected to remain zero at all |
+ | | | times, as DHCPv4-RESPONSE packets |
+ | | | are sent by the server and the |
+ | | | server is never expected to |
+ | | | receive them. A non-zero value |
+ | | | indicates an error. One likely |
+ | | | cause would be a misbehaving relay |
+ | | | agent that incorrectly forwards |
+ | | | DHCPv4-RESPONSE message towards |
+ | | | the server rather than back to the |
+ | | | clients. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-unknown-received | integer | Number of packets received of an |
+ | | | unknown type. A non-zero value of |
+ | | | this statistic indicates that the |
+ | | | server received a packet that it |
+ | | | was unable to recognize; either it |
+ | | | had an unsupported type or was |
+ | | | possibly malformed. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-sent | integer | Number of DHCPv6 packets sent. |
+ | | | This statistic is expected to grow |
+ | | | every time the server transmits a |
+ | | | packet. In general, it should |
+ | | | roughly match pkt6-received, as |
+ | | | most incoming packets cause the |
+ | | | server to respond. There are |
+ | | | exceptions (e.g. server receiving |
+ | | | a REQUEST with server-id matching |
+ | | | another server), so do not worry |
+ | | | if it is less than pkt6-received. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-advertise-sent | integer | Number of ADVERTISE packets sent. |
+ | | | This statistic is expected to grow |
+ | | | in most cases after a SOLICIT is |
+ | | | processed. There are certain |
+ | | | uncommon, but valid, cases where |
+ | | | incoming SOLICIT packets are |
+ | | | dropped, but in general this |
+ | | | statistic is expected to be close |
+ | | | to pkt6-solicit-received. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-reply-sent | integer | Number of REPLY packets sent. This |
+ | | | statistic is expected to grow in |
+ | | | most cases after a SOLICIT (with |
+ | | | rapid-commit), REQUEST, RENEW, |
+ | | | REBIND, RELEASE, DECLINE, or |
+ | | | INFORMATION-REQUEST is processed. |
+ | | | There are certain cases where |
+ | | | there is no response. |
+ +---------------------------------------------------+----------------+------------------------------------+
+ | pkt6-dhcpv4-response-sent | integer | Number of DHCPv4-RESPONSE packets |
+ | | | sent. This statistic is expected |
+ | | | to grow in most cases after a |
