Click 'Monitoring' in the navigation panel
Click the expand button against the 'Manage Mapping' and select 'Queues'

- Local - Monitor the queue which is available in the same machine
- Remote - Monitor queue from another machine in the same domain.
Message Age Units - This metric configuration allows you to choose the time parameter (Day/Hour/Minutes) for finding the duration of the message that exists in the queue
Threshold Monitoring Rules - Queue parameters such as Size, Journal Message count, Dead Letter Message Count, Active Message Count, Message Age can be monitored by configuring the threshold rules

Monitor the oldest message in the queue by setting up the Message Age Units and configuring the threshold parameter 'Message Age'.
Save the monitoring configuration by clicking the 'Save Configuration' button. The Queue will be added under the MSMQ tab in Alarms - Queues screen as shown below.
