Just an idea for consideration:
Various monitoring sub-processes are not being started by default and monitoring of their utilization from default Zabbix server/proxy health template produces not supported items, e.g.:
- 1x IPMI manager
- 1x IPMI poller
- 1x Java poller
- 1x SNMP trapper
- 1x VMware collector
- 1x report manager (server)
- 1x report writer (server)
- 1x service manager (server)
It is clear, items can be disabled in such case (workaround), but with the risk, they will be forgotten to be re-enabled after those processes later enabled+started. (Secondarily, disabled items may be also unwantedly re-enabled on some cases.)
Please, consider addition of "Check for not supported value" preprocessing step into those items in OOB templates, returning 0% utilization when not supported.
Secondarily, there could be also items monitoring numbers of running instances of all monitored sub-processes by OOB Zabbix server/proxy health (with zero considered as valid value), with triggers reacting on their changes.
Thank you in advance for consideration.
