Another, maybe much more basic way to monitor the workqueue are the follwing two options :
Option a)
System Administration
System health
Modify threshold for maximum messages in workqueue to a good number (100) we have 500
Add an email under Alerts and active Message Delivery as "Critical", edit the alerts settings to match your needs.
Option b)
Write a message filter on the CLI like :
CLIBasicMonitoringv1: if workqueue-count > 100 {
notify ("admin@domain.com", "Workqueue Monitoring Alert");
}
Unless you pull the data from an external system via either syslog or the API you always have the possible limitation that your notification email might get stuck within the email queue. There si supposed to be dedicated task for this but we have seen this happenig in the past before we changed over to moniutor via Splunk.
