About using NBSL to collect data from NetBackup primary servers
The OpsCenter Server uses the NetBackup Service Layer (NBSL) to collect most of the data types from a NetBackup primary server.
To collect the data types like capacity and traditional license from NetBackup, OpsCenter uses the bpjava protocol.
OpsCenter requires NBSL for all NetBackup monitoring, managing, and control functions. OpsCenter is affected if NBSL stops running on a managed NetBackup server.
If NBSL stops, OpsCenter may not capture any changes that were made to the NetBackup configuration. When NBSL restarts, OpsCenter correctly recaptures the latest state.
