You can use the following approach when tuning management packs:
■ Start by tuning the highest severity alerts first, and then work through towards the
lowest.
■ Remember that rules generate alerts that do not auto-close when the issue that caused
the alert is resolved. Alerts generated by monitors close, then the issue is fixed.
■ Evaluate how actionable an alert is. Actionable alerts are those where you are informed
what event occurred to trigger the alert, and where there are clear steps to resolve the
cause of the alert. Consider disabling alerts for rules where no action is required.
■ Evaluate the validity of the alert. Some alerts will inform you that they were triggered
by a particular event, such as a service failing. If you investigate and find that the
service that supposedly triggered the alert hasn't failed, assess whether you should
disable the alert.
■ Evaluate whether multiple alerts are informing you about the same issue. You can sup-
press those alerts that are providing you with duplicate notification about the same
issue.
Microsoft provides the following recommendations for management pack tuning:
■ Only import a single management pack at a time. This gives you a chance to concen-
trate on tuning one management pack. Tuning more than one management pack
concurrently consumes substantially more time.
■ Review alerts reported for servers monitored by the newly imported management
pack. Use the Alerts and Most Common Alerts reports to determine which alerts are
being created the most often, and use this as a starting point for tuning.
■ Disable monitors or rules when you determine that you don't need to be notified
about a particular issue.
■ Alter the threshold of the monitor generating the alert if you want the underlying issue
to be monitored, but not at the sensitivity at which the current monitor is configured.
■ Save overrides to an unsealed management pack that uses the name Management-
Pack_Overrides. For example, call the management pack that stores the overrides for
the Microsoft Exchange Server 2013 management pack, Microsoft Exchange Server
2013_Overrides. This simplifies the process of keeping track of overrides.
