As of now and as far as I know there is no option available from the DPA.
Try the following and let me know if it gives you alert on NMC the next time VBA services are taken down.
1. Log in to NMC and wait for the NMC Enterprise window to be displayed.
2. Right-click Enterprise from the left navigation tree and select New > Host.
3. Enter the VMware Backup Appliance hostname or IP and click Next. The Select Host Type dialog displays.
4. Select Avamar and click Next, and then click Finish.
This should now give you a summary of VBA status when you click on the name, just like how the NetWorker details show up when you click NetWorker server name on the LHS of navigation tree.
let me know, how that works,
If it's possible we want receive alerts in DPA so we can pass it on to Microsoft SCOM.
So using NMC is not the preffered option is our case.
AFAIK it isnt possible on the latest versions (both DPA and VBA).
Let me know if you hear anything from EMC On this.
