Chak Kwok Yin,
If you’re asking if the alert will display the current queue depth as part of the alert message, then the answer would be “No”; the alert message displays the criteria that was met to trigger the alert – i.e. “OB queue depth >= 50 for 600 seconds”. However, to address the second part of your question, you can define a single alert with the same criteria, selecting multiple connections for the ‘Source’, and simply select “any” as your ‘Source Count’; then if any one of the connections meets the criteria, the alert would trigger and the alert message would indicate the connection that triggered the alert.
Hope this helps.
