Read the first 6 Cribl Monitoring & Troubleshooting flashcards as text

  1. Which Cribl feature enables you to replay events stored in a Persistent Queue after a destination outage is resolved?

    Answer: The 'Replay' action on the Persistent Queue in the destination settings

    Cribl's Persistent Queue includes a Replay action that allows operators to resend queued events to the destination once connectivity is restored.

  2. How does the Cribl Pipeline Profiler help with performance troubleshooting?

    Answer: It shows the processing time and event count for each function in the pipeline

    The Pipeline Profiler breaks down per-function processing time and event counts, helping identify bottlenecks within the pipeline.

  3. When troubleshooting a Cribl Source that is not receiving events, which diagnostic step should be performed first?

    Answer: Verify network connectivity and firewall rules between the source host and the Cribl input port

    Network connectivity and firewall verification is the first step because no data can reach Cribl if the port is blocked or the source cannot reach the input address.

  4. What does a high 'Parse Failure' rate on a Cribl Source typically indicate?

    Answer: The Event Breaker rules do not match the incoming data format

    High parse failure rates indicate that the configured Event Breaker pattern does not match the format of incoming events, causing parsing errors.

  5. Which command-line tool included with Cribl can be used to test connectivity from a Worker node to a downstream destination?

    Answer: cribl test-connection or standard network tools like curl/nc from the Worker host

    Standard network tools such as curl or netcat (nc) run from the Worker host are used to verify TCP/HTTP connectivity to downstream destinations.

  6. In Cribl, what does the 'Throttle' function do when added to a pipeline during troubleshooting?

    Answer: It limits the event throughput rate to reduce load on downstream systems

    The Throttle function caps the rate of events passing through the pipeline, useful for temporarily reducing load on struggling downstream destinations.
