  1. How does Cribl Stream distribute incoming TCP connections across multiple worker processes?

    Answer: Round-robin across worker processes

    Cribl uses round-robin distribution to spread incoming TCP connections evenly across available worker processes.

  2. What certificate format does Cribl require when configuring TLS on a source or destination?

    Answer: PEM-encoded certificates

    Cribl requires PEM-encoded certificates (typically .pem or .crt files) when enabling TLS on sources or destinations.

  3. When a Cribl destination recovers after an outage, what happens to events stored in the Persistent Queue?

    Answer: Cribl automatically replays queued events from the Persistent Queue in order

    When the destination recovers, Cribl automatically replays events stored in the Persistent Queue, ensuring no data is lost during the outage.

  4. What is the effect of enabling load balancing across multiple endpoints in a Cribl destination?

    Answer: Events are distributed round-robin across the configured endpoints

    With load balancing enabled, Cribl distributes events in round-robin fashion across all configured endpoints in the destination.

  5. What is the purpose of setting an IP allowlist on a Cribl source?

    Answer: Restrict which source IP addresses or CIDR ranges can send data to the source

    An IP allowlist on a source limits connections to only the specified IP addresses or CIDR ranges, rejecting all other clients.

  6. When multiple authentication tokens are configured on a single Cribl HTTP source, what is the primary benefit?

    Answer: Different clients can authenticate independently while sending to the same source endpoint

    Multiple tokens allow different client applications or teams to authenticate with separate credentials while all sending data to the same HTTP source.

  7. Which configuration setting controls how long a Cribl TCP source waits before closing an idle connection with no data activity?

    Answer: Idle timeout

    The idle timeout setting determines how long an inactive TCP connection is held open before Cribl closes it to free resources.
