bootchart2 was created from the fusion of three separate pieces of work. First – the original bootchart: a shell script, and a Java visualisation tool.
bootchart2 replaces the Java visualisation with the more friendly and flexible pybootchartgui.
bootchart2 embeds a new collector, based on a port to C of the inner-loop of the original bootchart collector shell-script.
Key Features
- Higher resolution – the taskstat interface gives nanosecond timing information, where /proc/*/stat information is far, far less reliable and useful.
- Higher performance – the C re-write allows us to collect more data, more quickly – sampling at ~50+Hz.
- Using PROC_EVENTS we can determine accurate process parentage
- without needing to use a ‘acct’ binary.
- No Java dependency – with the visualisation in easy-to-hack python, development is quicker, and dependencies more commonly found.
- Simpler wrappers – by using ptrace to connect to and extract data from the collector, we no longer require a consistently visible set of logs accessible via a shared file-system.
- Built-in visualisation – allowing some level of interaction, zoom and so on.
- Better rendering – render to PNG or SVG, with added event annotation support, and ‘show more’ functionality. Cumulative, and total CPU time graphing in the boot-chart.
