Where does a forwarder save data when an indexer cannot be reached?

  1. Local memory

  2. Output Queue

  3. Wait Queue

  4. Error Queue

The correct answer is: Wait Queue

The forwarder saves data in the Wait Queue when it cannot reach the indexer. This mechanism allows the forwarder to temporarily store events that it is unable to send due to network issues or when the indexer is offline. The purpose of the Wait Queue is to ensure that no data is lost during these downtimes; it acts as a buffer until connectivity is restored or the indexer becomes available again. Once the connection is re-established, the forwarder will then attempt to send the events that were held in the Wait Queue to the indexer for indexing. This behavior is crucial for maintaining data integrity and ensuring that all events are processed in the correct order once normal operations resume. Understanding this process is vital for effectively managing data flow in a Splunk environment.
