Queue monitoring must be configured with threshold and action.
Monitors are automated “process watchers” that respond to performance changes, and can be useful in detecting outages and alerting administrators where attention is needed. Exchange has built-in monitors that enable the administrator to generate alerts if thresholds are reached, better enabling them to react in a timely fashion. The intent of this check is for system administrators to have awareness of performance changes on their network. Notification choices include email an alert to an email-enabled account, for example, an email Administrator, or invoke a script to take other action, for example, to add an Event to the Microsoft Application Event Log, where external monitors might detect it. Data elements configured to be monitored should be specific to the organization’s network. .
Open the Exchange Management Console
In the left pane, navigate to and select Microsoft Exchange On-Premises
<server.domain> --> Toolbox
In the Right pane double click on Performance Monitor
In the left pane, navigate to and select Performance Logs and Alerts --> Data Collector Sets --> User Defined
Right click on User Defined and configure the system to use User Defined data collection for monitoring the queues.
Note: If a third-party application is performing monitoring functions, the reviewer should verify the application is monitoring correctly and mark the vulnerability NA. Open the Exchange Management Shell and enter the following command: perfmon In the left pane, expand and navigate Data Collector Sets >> User Defined. If no sets are defined or queues are not being monitored, this is a finding.
