Large Alarm Trees

This BPA test is executed on one DMA per cluster. It will fetch active alarm trees and check if any are getting too large. If this is the case, it could have a serious impact on several DataMiner processes, so you will have to take the necessary corrective actions.

This BPA test is available from DataMiner 10.5.9/10.6.0 onwards. You can run it in System Center on the Agents > BPA tab.

  • x large alarm trees detected, followed by a list of alarm tree IDs with the corresponding exact size.

Not Executed

If the test fails to execute for unexpected reasons and cannot provide a conclusive report because of this, the following message can be shown:

  • BPA execution timed out after 10 minutes. In this case, it took too long to collect all the necessary information.
Note

If you get the exception BPA doesn't have valid signature, this means the BPA test is unsigned. To resolve this issue, contact Skyline to ask for the signed version of the BPA or upgrade DataMiner.
