How the agents will behave after stopping APM cluster for a long time (few days, weeks)?
If we shut down one APM cluster to limit license usage. The question is: can we leave the instrumented applications for a few days without connection to APM cluster? Will this have a negative impact on the application?
Release : 10.7.0
Completely stopping em cluster will have the below impact
1: All monitoring data will be lost until the em is up. As agent wont store any collected data ,
2: Any integration with APM EM with other tool will be impacted .
3: If any agent side intergration with other tool , like site monder SSO , Infrastucture agent etc ,that data too will be lost.
4: Agent logs will be keep on writing that there is connectivity issue , and if logs wont roll back properly then disk space will be used .
5: Ideally it should not effect application side, but in case you have test environment can check 1st there.
