What does the command 'splunk cmd btprobe' achieve?

The command 'splunk cmd btprobe' is used primarily for managing the behavior of Splunk when monitoring files by resetting a checkpoint. This means that it can be used to adjust where Splunk resumes reading data from a file that is being monitored, essentially allowing it to process data from a specific point in that file. Checkpoints are critical in file monitoring because they help prevent the duplication of data ingestion during updates or if a file is rotated.

In scenarios where log files or data sources are edited or rewritten, the checkpoint ensures that Splunk does not reprocess data that has already been indexed. By resetting the checkpoint, users can address issues with file monitoring, such as ensuring accurate data ingestion after changes in the data source.

While other options mention starting services, creating backups, or clearing logs, these tasks are managed by different commands and functionalities within Splunk. Therefore, focusing on the specific capability of 'btprobe' in relation to file monitoring checkpoints clarifies its designated purpose in maintaining data integrity during collection and indexing processes.
