Using DTrace to view diagnostic logs

If you encounter problems when you store or retrieve archived data with the Enterprise Vault Amazon S3 storage migrator, you can run the DTrace utility to help you identify their cause. DTrace let you monitor multiple services simultaneously, write the trace to a file, filter for specific words, and trigger tracing based on filters.

The following table lists the migrator processes for which you can get diagnostic logs with DTrace.


We recommend that you set the monitoring level to Verbose in all cases.
