Why is restarting production services a poor first diagnostic step?
Select an answer to reveal the explanation.
Short Explanation
A restart can wipe the transient state that just showed you what went wrong. You lose the evidence, and the real cause comes back later.
Full Explanation
Restarting production services is a poor first diagnostic step because it resets in-memory state, connections, and buffers, which are frequently the very things that would have explained the failure. The symptom disappears, the cause persists, and the next occurrence starts from zero. The claim that restarting services is not permitted while Instana agents are installed is incorrect because restarts are permitted and are sometimes the right remediation, just not the right first diagnostic. The claim that restarting services permanently deletes all historical telemetry for those services is incorrect because telemetry already sent to the backend is retained independently of the service. The claim that restarting services requires the backend to be reinstalled afterwards is incorrect because a service restart has no such consequence. For the exam, gather evidence before taking actions that alter state.
