powerdns plugin: Use `LOCALSTATEDIR' instead of "/var".
I was working on updating Gentoo's ebuild and I noticed that localstatedir was
not used in certain places. Please review these patches and consider them.

perl plugin: Re-get the perl interpreter after parsing each configuration option.
The current perl interpreter might change while parsing the configuration
(e.g. the first interpreter is created by the "LoadPlugin" option), so this is
to make sure that we're using the right interpreter at all times.

contrib/collection3: Added the ability to `flush' data sets.
Both, bin/index.cgi and bin/graph.cgi can now send a FLUSH command to
the daemon via the Collectd::Unixsock module. For this to work you will
have to add the path to the UNIX socket of the `unixsock' plugin to the
configuration file `collection.conf'.
The configuration looks like this:
UnixSockAddr "/var/run/collectd-unixsock"

snmp plugin: Fix a possible memory leak.
The result was not freed when `csnmp_instance_list_add' failed. This
rarely happens in 4.3, but later versions will be more strict in the
function, so this became a problem.

configure.in: Look for ip_vs.h in the kernel sources.
Developers,
I am writing an updated ebuild for gentoo and I made this patch that allows
ip_vs.h to be located and the ipvs module to build. Normally I would include
this with the ebuild, but I thought it may be beneficial to send it to you.
Please review it and let me know what you think. I am still inexperienced with
autotools so the patch may not be well put together. If you would consider
applying it or a similar patch, please let me know so I can adjust the ebuild
accordingly.

contrib/collection3: Add JavaScript code to unify the timespan of all graphs.
Using the new ``Set all images to this timespan'' button one can now easily
show the same timespan in all graphs. This allows to compare different graphs
much more easily.
contrib/collection3: Add a generic `instance' placeholder.
It will be replaced by either the type or plugin instance, depending on
which is defined.. This is handy for temperatures and stuff like that,
where sometimes the type instance doesn't exist.
vserver plugin: Use `readdir_r' instead of `readdir'.
`readdir' is not thread safe, so use the (more thread safe) `readdir_r'.
Also, don't use the non-standard `d_type' member of the `dirent'
structure - it's not portable.
I'm aware that this plugin is very Linux specific and Linux most likely
will never use another C library than the GNU libc, but using this
member prevents me from compiling with the most restrictive `strict'
settings..

src/plugin.c: Initialize plugins before checking if read callbacks are available.
plugin_init_all() checks if any read callbacks are available before starting
the read threads. A few plugins register their read callback from their
init callback though. By initializing the plugins before that the read
threads are still started correctly if all plugins register the read
callback in the init callback.

email plugin: Don't unlink the socket file on startup.
Usually, collectd runs as user root, thus making it an unsafe operation to
unconditionally remove the file even though one should be able to assume
that it "belongs" to collectd.

Madwifi writes the actual dBm values into /proc.
So we have (at least for now) three possible types of values:
( x > 0.0 && x <= 100.0 ) current implementation: x is in percent (?)
( x > 100.0 && x <= 255.0 ) broadcom: range intersects with percents but
values below 100.0 (100.0 - 255.0 = -155.0 dBm)
are somewhat unlikely to occur
( x < 0.0 ) atheros: value is already in dBm
A patch which implements the two additional possibilities in collectd's wireless
plugin can be found in the OpenWrt Trac:
I have noticed that disk graphs are displayed by collection.cgi as
disk (71687000) instead of the correct disk name on 2.4.x linux
kernels.
The problem seems caused by the fact that the position of disk name of
/proc/partitions (used in 2.4 kernels) differs from /proc/diskstats
(used in 2.6 kernels).
I include as attachment a patch that seems to fix this problem.
I have tested it on 2.4.20 (REDHAT 9) and 2.6.24.4 (Debian Sid) systems.
Thanks a lot for Collectd. It is a _very_ useful program.

network plugin: Don't blindly re-initialize everything in the init callback.
Under Solaris the init functions are called every time the kstat chain
is updated. Since, among other things, send_buffer_fill was set to zero
here, the plugin ``forgot'' about values.
Thank you very much to Eric LeBlanc for debugging this issue.

perl plugin: Don't abort if initializing the interpreter failed.
There is no reason to shutdown collectd completely just because of some
Perl specific error. An error message is logged in this case, so the user
has means to detect it.
