Accepting into Beta 2 program, and assigning to Emma for review. Hi Shirly, According to collectd documentation, the CPU plugin is actually a jiffie rather than a percentage: How important is this distinction in your opinion? "The CPU plugin does not collect percentages. It collects “jiffies”, the units of scheduling. On many Linux systems there are circa 100 jiffies in one second, but this does not mean you will end up with a percentage. Depending on system load, hardware, whether or not the system is virtualized and possibly half a dozen other factors there may be more or less than 100 jiffies in one second. There is absolutely no guarantee that all states add up to 100, an absolute must for percentages. " Thanks Emma Please review https://collectd.org/documentation/manpages/collectd.conf.5.shtml#plugin_cpu We use set the following parameters: ReportByState true ReportByCpu true ValuesPercentage true That means we get values in percentage, pre cpu. |
