Discarded Counter Monitor

Jalasoft.Xian.Server.DiscardedCounterMonitor (UnitMonitor)

Knowledge Base article:

Summary

If the Connector Module Server discards too many counters(over the defined threshold) per interval, The monitor will generate a warning alert. This alert is auto-resolved if the discarded counters are below the defined threshold

Causes

Possible causes may be:

-A Management Pack of a plug-in is missing in Operations Manager so the rule Guid cannot be obtained.

-Wrong configuration between Connector and Connector Module.

-The defined threshold for discarded counters is too low for the environment.

Resolutions

Verify:

-If the Management Pack of the plug-in is imported correctly in Operations Manager.

-That Connector and Connector Module are correctly configured.

-Override the threshold value of the "Discarded Counter Monitor" to a proper value.
