after six months of normal operations the influxdb (version 1.2.4)
started to consume lot more of memory and cpu cycles since about ten days.
Altogether the influxdb occupies about 390 MB, split into
360 MB for /var/lib/influxdb/data,
30 MB for /var/lib/influxdb/wal and less than
1 MB for /var/lib/influxdb/meta
There are in average 3 write ops and 1 read ops. The influxdb processes allocate about 400 MB memory.
Taking a deeper look into the system calls, I can see per minute:
140.000 futex (fast user-space lockings) calls and
360.000 clock_gettime calls
I’m doubting whether this is a normal behaviour?
Any pointers how to dig deeper are appreciated!
