  1. What does the Cribl 'Dead Letter Queue' (DLQ) capture?

    Answer: Events that failed processing and could not be delivered to any destination

    The Dead Letter Queue captures events that failed all processing or delivery attempts, allowing operators to inspect and remediate failed data.

  2. Which Cribl monitoring integration allows you to export internal metrics to an external observability platform like Prometheus?

    Answer: Configuring a Cribl Internal Source of type 'Cribl Internal Metrics' routed to a Prometheus-compatible destination

    Cribl's 'Cribl Internal Metrics' source collects internal telemetry that can be routed via a pipeline to a Prometheus remote write or compatible destination.

  3. What is the recommended action when a Cribl Worker node's CPU utilization consistently exceeds 90%?

    Answer: Add additional Worker nodes to the Worker Group to distribute load

    Consistently high CPU on a Worker node indicates the current nodes cannot handle the event volume, and scaling out with additional Workers distributes the processing load.

  4. In Cribl, how can you identify which pipeline function is responsible for the largest increase in event size?

    Answer: Using the Pipeline Profiler to compare input and output event sizes per function

    The Pipeline Profiler reports per-function metrics including event size changes, making it easy to identify which function inflates event size the most.

  5. What Cribl feature helps diagnose issues where events are being routed to the wrong destination?

    Answer: Previewing the Routes table with a sample event to trace which route matches

    Using the Routes preview with a sample event shows which route conditions match, helping diagnose incorrect routing decisions.

  6. Which log level should be temporarily enabled on a Cribl Worker node to capture detailed debug output for a hard-to-reproduce issue?

    Answer: DEBUG

    Setting the log level to DEBUG on a Worker node captures detailed execution traces, though it should be reverted after troubleshooting due to high log volume.
