MM Metrics and Features Configuration : Understanding and Configuring Alerts

Understanding and Configuring Alerts
The MM server can monitor key performance indicators provided in the metric charts and tables, and generate notifications (alerts) when a specified condition is met.
See Working with Panels and Panes for some examples of charts and tables.
Understanding Alerts
Alert conditions are met by comparing a specified metric value with a reference value. The reference value can be a constant, or it can be another value in the same pane. As an example of a constant reference, you can configure an alert to trigger when the number of deadlocked threads exceeds a certain number. As an example of a reference that is another value in a pane, you could configure an alert to trigger when Used memory exceeds 95% of Max memory.
Each alert has an alert level (critical, warning, and normal), and a configurable message. Messages use the Java Message Format syntax. You can, as desired, set up three alerts of different severity for the same metric, using different threshold values.
Severity is defined in terms of the following three levels:
Alerts are viewable in the System Alerts pane of the Cluster Overview. See Cluster Overview for an example.
The presence of alerts can also be used to define the health level value for any monitored entity. See Configuring Health Metric Rules.
