From 6f4e8180b5b4857eaf6caf410fd3a4a41ed85930 Mon Sep 17 00:00:00 2001 From: Patrick Ohly Date: Wed, 30 Nov 2016 10:50:01 +0100 Subject: buildstats: add system state sampling /proc/[diskstats|meminfo|stat] get sampled and written to the same proc_.log files as during normal bootchat logging. This will allow rendering the CPU, disk and memory usage charts. Right now sampling happens once a second, triggered by the heartbeat event.That produces quite a bit of data for long builds, which will be addressed in a separate commit by storing the data in a more compact form.
