more and more process of ipmi-sensors when multiple prometheus scrape from the same ipmi-exporter
chris-fengtian-guo opened this issue · 3 comments
on some hardware have such issue but not all
I meet the issue. because the ipmi-sensors execute slow and when there are multiple prometheus scape from the same ipmi-exporter. more and more process of execute of ipmi-sensors command and each ipmi-sensors commands take more and more time to finish.
the prometheus scape_interval is 5 second
just 10 miniutes later after ipmi-exporter start there are 44 ipmi-sensors process.
and I have to jump from this issue by configure prometheus's configure. by increase scrape_interval from 5 seconds to 10 seconds .
and this issue less worse but not fixed. when multiple prometheus scape from the same ipmi-exporter
and 20 miniutes later there are 134 ipmi-sensors

- I add following drfit patch to fix such issue and my patch is base on

Merge pull request #76 from xibolun/master
Update doc/configuration.md
1.2) this is my drift patch by add ia cache for output of pmi-sensors command and when there are more than one ipmi-sensors process exist I use the cache.

add cache for ipmi-sensors command output
Because some hardware the ipmi-sensors spend much more time than
1 second.
so when multiple prometheus scape from the same ipmi exporter,
each ipmi-sensors take more and more time to run. and there are
more and more process of ipmi-sensors at the same.
some times each ipmi-sensors command take more than 20 miniutes to
finish
so the solution is add the cache of output of ipmi-sensors to avoid
more and more ipmi-sensors process run in same time

Hello there. Sorry for the late reply. I think using a 5 second scrape interval is very ambitious for IPMI. Note that all collectors are run in serial. How many collectors do you run?
Also, can you post your patch again? The formatting unfortunately makes it impossible to read.
