-Bootchart - a 'startup' graphing tool
-
---
-
-Bootchart is a tool, usually run at system startup, that collects and graphs
-the CPU and disk load of the system as it works. The output of bootchart is
-an SVG graph. Normally, bootchart is invoked as `bootchartd` by the kernel
-by passing "init=/sbin/bootchartd" to the kernel. Bootchart will then fork
-init off to resume normal system startup, while monitoring and logging
-startup information in the background.
-
-After collecting a certain amount of data (usually 15-30 seconds) the logging
-stops and a graph is generated from the logged information. This graph
-contains vital clues to which resources are being used, in which order, and
-where possible problems exist in the startup sequence of the system.
-
-Of course, bootchart can also be used at any moment in time to collect and
-graph some data for an amount of time. Bootchart does not even require root
-privileges to do so, and will happily run as a normal user. Bootchart graphs
-are by default written time-stamped in /run/log.

-
-This version of bootchart was implemented from scratch and inspired by former
-incantations of bootchart:
-
-- The original bash/shell code implemented bootchart. This version logged all
-data into a compressed tarball for later processing, and did not create a graph
-on it's own.
-
-- The C-code implementation found in Ubuntu. This version replaced above shell
-code version with a faster and efficient data logger, but still did not graph
-code itself.
-
-- the original Java-based bootchart, the original graphing program that created
-a bootchart graph from logged data.
-
-- the pybootchartgui.py program, which created a graph based on the data logged
-by either standalone data logger.
-
-The version you are looking at combines these 2 parts into a single program,
-which makes running it and creating graphs a bit more efficient and simple.
-You can now run a single program at startup instead of 2. There are no timing
-problems (the graphing stage will never run if the logging stage didn't
-finish). The logged data isn't being written to disc first, then read again.
-Also, the data kept in memory is reduced to the absolute minimum needed to
-keep memory use low.
-
---
-
-Requirements: glibc. Your kernel must have procfs support and several
-proc output options enabled:
- CONFIG_PROC_FS
- CONFIG_SCHEDSTATS
- CONFIG_SCHED_DEBUG
-at a minimum. bootchartd itself does not require any graphics library
-to generate the SVG output file.
-

-
-Configuration: please see bootchartd --help, as well as /etc/bootchartd.conf
-and/or /usr/share/doc/bootchart/bootchartd.conf.example for a list of
-configurable options.
