CONFIG_CFS_BANDWIDTH
- For systemd-bootchart, several proc debug interfaces are required:
- CONFIG_SCHEDSTATS
- CONFIG_SCHED_DEBUG
-
For UEFI systems:
CONFIG_EFIVAR_FS
CONFIG_EFI_PARTITION
works with ^C
- add documentation to systemd.daemon
-* bootchart:
- - plot per-process IO utilization
- - group processes based on service association (cgroups)
- - document initcall_debug
- - kernel cmdline "bootchart" option for simplicity?
-
* udev-link-config:
- Make sure ID_PATH is always exported and complete for
network devices where possible, so we can safely rely

- <para>
- <command>systemd-bootchart</command> is a tool, usually run at
- system startup, that collects the CPU load, disk load, memory
- usage, as well as per-process information from a running system.
- Collected results are output as an SVG graph. Normally,
- systemd-bootchart is invoked by the kernel by passing
- <option>init=<filename>/usr/lib/systemd/systemd-bootchart</filename></option>
- on the kernel command line. systemd-bootchart will then fork the
- real init off to resume normal system startup, while monitoring
- and logging startup information in the background.
- </para>
- <para>
- After collecting a certain amount of data (usually 15–30
- seconds, default 20 s) the logging stops and a graph is
- generated from the logged information. This graph contains vital
- clues as to which resources are being used, in which order, and
- where possible problems exist in the startup sequence of the
- system. It is essentially a more detailed version of the
- <command>systemd-analyze plot</command> function.
- </para>
- <para>
- Of course, bootchart can also be used at any moment in time to
- collect and graph some data for an amount of time. It is
- recommended to use the <option>--rel</option> switch in this
- case.
- </para>
- <para>
- Bootchart does not require root privileges, and will happily run
- as a normal user.
- </para>
- <para>
- Bootchart graphs are by default written time-stamped in
- <filename>/run/log</filename> and saved to the journal with
- <varname>MESSAGE_ID=9f26aa562cf440c2b16c773d0479b518</varname>.
- Journal field <varname>BOOTCHART=</varname> contains the
- bootchart in SVG format.

- started, as it may result in extremely large graphs. The time

-
- <para>This version of bootchart was implemented from scratch, but
- is inspired by former bootchart incantations:</para>
-
- <variablelist>
- <varlistentry>
- <term><emphasis>Original bash</emphasis></term>
- <listitem><para>The original bash/shell code implemented

- graph anything, only generated data.</para></listitem>
- </varlistentry>
-
- <varlistentry>
- <term><emphasis>Ubuntu C Implementation</emphasis></term>
- <listitem><para>This version replaced the shell version with a
- fast and efficient data logger, but also did not graph the
- data.</para></listitem>
- </varlistentry>
-
- <varlistentry>
- <term><emphasis>Java bootchart</emphasis></term>
- <listitem><para>This was the original graphing application for
- charting the data, written in java.</para></listitem>
- </varlistentry>
-
- <varlistentry>
- <term><emphasis>pybootchartgui.py</emphasis></term>
- <listitem><para>pybootchart created a graph from the data
- collected by either the bash or C version.</para></listitem>
- </varlistentry>
- </variablelist>
-
- <para>The version of bootchart you are using now combines both the
- data collection and the charting into a single application, making
- it more efficient and simpler. There are no longer any timing
- issues with the data collector and the grapher, as the graphing
- cannot be run until the data has been collected. Also, the data
- kept in memory is reduced to the absolute minimum needed.</para>
