An Instana installation is behaving unexpectedly and the cause is unclear. What is the appropriate first diagnostic step?
Select an answer to reveal the explanation.
Short Explanation
Start with the logs. Collect the relevant agent and backend logs for the affected components and time period, then read them to isolate where the failure occurs. They show what the software actually did, not just how it looks from outside.
Full Explanation
The correct approach is to collect the relevant agent and backend logs for the affected components and time period, then read them to isolate where the failure occurs. Agent and backend logs record the operations, errors, and connection attempts that explain the behavior, and scoping them to the affected components and time keeps the volume workable.
Capturing browser screenshots of the interface as the primary evidence is incorrect because a screenshot shows a symptom without the underlying detail; it supplements logs rather than replacing them.
Clearing the existing logs so a clean set can be gathered from a fresh attempt is incorrect because deleting logs destroys the record of the failure that has already occurred, including anything support would need.
Restarting the production services immediately to see whether the symptom clears is incorrect because a restart often clears the evidence along with the symptom and provides no explanation, while carrying production risk.
For the exam, put log collection ahead of restarts and screenshots.
