Some clients ( about 20% ) have Monitoring error.
Some started working after uninstall the agent and reinstall it. But there are some clients - the error will not disapear.
There is also a Server which has the state "Monitoring: Error" but it was ok, after reinstalling - after one day it falls back to "Monitoring: Error".
I tried to stop ops service and delete file and start it again.
But there was no effekt. Also the switch /clearchache has no effect.
Thanks for any ideas, regards Andy
