Question:
About behavior of Agent
1) What happens to information acquired by Agent while EnterpriseManager is stopped? Is it discarded or retransmitted when Enterprise Manager starts?
2) If EnterpriserManager is started, will the Agent resend the data to EnterpriseManager without doing anything?
3) Is EnterpriserManager stopped, does the system incorporating Agent have any impact? (Response is delayed, resources are soaring, etc.)
4) Is there anything to pay attention to?
Environment:
APM 10.x Agent
Answer:
1) The metric information created by the Agent is discarded in a state where there is no destination (the state is not in the state where the EM can receive metrics).
2) We do not retransmit EM metrics being stopped. As soon as EM is started, the Agent connects to the EM and resumes sending the metric information.
3) Yes, there is no such thing as affecting the system such as slow response, resource soaring etc.
4) Nothing in particular.
