How OpsCenter collects data from NetBackup
OpsCenter is used to monitor, manage, and report on NetBackup master and media servers, clients, and policies. To perform the monitoring, management, and reporting functions, OpsCenter collects data from the NetBackup master servers. The NetBackup data collection and management logic that OpsCenter uses is built into NetBackup master servers. This logic is included in the NetBackup Service Layer (NBSL).
Note:
OpsCenter only uses the NBSL on master servers for data collection. Though NBSL is also included on media servers, OpsCenter does not use it. You must add only master servers to the OpsCenter console. You must not add any media servers to the OpsCenter console.
NBSL provides a single point of access to key NetBackup data, objects, and change events. The NetBackup UI also uses NBSL. NBSL runs as a service or daemon and has local configuration information, but no local database.
OpsCenter uses NBSL for all NetBackup monitoring, managing, and control functions. If NBSL service stops running on a managed NetBackup server, OpsCenter gets affected.
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.
See Data collection status of a master server.
The OpsCenter Server software collects data from NBSL in the following ways:
Initial data load
Listening for change notifications
Whenever OpsCenter server software starts, when data collection for a master server is enabled or when a master server is added to OpsCenter, the OpsCenter server starts collecting all the available data from NetBackup master server into the OpsCenter database using NBSL. The initial data load happens serially for each data type. As soon as the initial data load is complete, OpsCenter server software listens to the notifications from NBSL for any change in NetBackup data, and updates the OpsCenter database.
Note:
Consider a scenario when you add a master server or when OpsCenter Server software starts after a long time, or when the data collection for a master server is enabled after a long time. In this case, it may take some time for the OpsCenter server to collect all data (such as media, jobs, images, drives etc.) from the NetBackup master server and insert it into the OpsCenter database.
Consider a scenario where a master server is already added on the OpsCenter console, and you uninstall and then reinstall NetBackup on the master server. In this case, you should disable the data collection () before you uninstall NetBackup. Once NetBackup installation completes, you must enable the master server. Enabling the master server marks the existing master server as retired and also create a new master server with the freshly installed NetBackup.
See Adding a master server or an appliance master server in the OpsCenter console.
Note:
After you install a NetBackup Master Server, you should enter the OpsCenter Server name in the NetBackup Host Properties.
Veritas Private Branch Exchange (PBX) is used for communication and requires a port to be opened on the OpsCenter server and the NetBackup master server for input and output. The default PBX port that is used is 1556. You cannot configure the PBX port in OpsCenter.
