MM Metrics and Features Configuration
The MM component provides a console that enables you to monitor the status of deployed TIBCO BusinessEvents engines and perform management tasks.
You can configure thresholds and other settings for the various health metrics and alerts to suit your needs. You can also configure actions to take based on alerts or health level status values. These configuration tasks are done in the CDD file for MM, MM.cdd.
See the following sections for details:
- Configure alerts:
- Configure health metric rules:
- Configure actions to take upon triggering of an alert of change in health level:
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 Health Metric Rules Configuration.
