Table: Where to monitor the main MSDP processes

What

Where to monitor it

NetBackup Deduplication Engine

On Windows systems, in the NetBackup Administration Console Activity Monitor Services tab.

On UNIX, the NetBackup Deduplication Engine appears as spoold in the Administration Console Activity Monitor Daemons tab.

The NetBackup bpps command also shows the spoold process.
