Re: [influxdb] Constantly some CPU load on 0.9

[Teemu Kanstrén]

OK, thanks for the info. With our other server running 0.13 I see it is 
about the same loads, although it has a bit more constant writes. I guess 
it must be these background processes. Generally it is not too much for me, 
so no problem, just good to know.

Re: [influxdb] Constantly some CPU load on 0.9

Even if there is no external write or query load, InfluxDB is writing
statistics about itself back to itself. Any configured continuous queries
will also require resources. In addition, there are housekeeping chores
related to Raft and file compaction that can cause a low steady-state level
of CPU usage.
