Steps to reproduce:
I'm periodically loose all history and trends data of random VMWare datastore from my hosts. There are 1-2 "loss events" per day. Data losses are random in time and affected host.
It only affects datastore performance data, all other VMWare data are not showing the issue.
All historical data before the "loss event" is erased in Zabbix (see screenshot).
Whenever such an event happens on any datastore / any host, I see this line in the zabbix_server.log:
I have enough VMWare collectors enabled and I have increased them from 10 to 30 with a timeout of 30s (was 10 before) each, this did not help. Also no other VMWare performance data but datastore data is affected.
I would expect that - even if the datastore performance could not be fetched once in any minute - that only this certain minute-value would be missing/not available, but under no circumstances this should lead to a complete loss of all previous historical data!
