buildstats.bbclass: add functionality to collect build system stats
There are a number of timeout and hang defects where it would be useful to collect statistics about what is running on a build host when that condition occurs. This adds functionality to collect build system stats on a regular interval and/or on task failure. Both features are disabled by default. To enable logging on a regular interval, set: BB_HEARTBEAT_EVENT = "<interval>" BB_LOG_HOST_STAT_ON_INTERVAL = <boolean> Logs are stored in ${BUILDSTATS_BASE}/<build_name>/host_stats To enable logging on a task failure, set: BB_LOG_HOST_STAT_ON_FAILURE = "<boolean>" Logs are stored in ${BUILDSTATS_BASE}/<build_name>/build_stats The list of commands, along with the desired options, need to be specified in the BB_LOG_HOST_STAT_CMDS variable delimited by ; as such: BB_LOG_HOST_STAT_CMDS = "command1 ; command2 ;... ;" Signed-off-by: Sakib Sajal <sakib.sajal@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
