Hi Wei,
I am going to tweak this value, however which is the purpose of
StatsCollector ? Which impact will it have by increasing this value ?
I compared with an older ACS management server and saw the footprint
generated for StatsCollector was not so consuming
I stopped all other management servers on acs 4.16 and kept only one
management server, i see StatsCollector entries several times a minute
Do the entries i have in logs are normal ?
I have this regularly in them :
