IMS metrics

BMC AMI Ops Monitor for IMS Online views and background monitors provide important metrics for IMS. These are described in the following topics:
IMS metrics provided by views
The following metrics are available in the BMC AMI Ops Monitor for IMS Online views. For information about using this table, see Using the metric tables.
Before you create alarms based on these metrics, review the best practices for alarms in Managing application exceptions.
The following figure does not provide recommended view filters. However, you can specify filters to focus a view on a particular application, especially if the application resources, for example, transactions, databases, and programs, use a similar naming convention. If you specify filters, be sure to update the filters to reflect changes in the application, and reapply the filters after the installation of product maintenance or new product versions.

IMS metrics provided by monitors
The metrics in the following table are available from the BMC AMI Ops Monitor for IMS Online background monitors.
You can specify monitor options, such as WIF, to ensure that a condition persists for a certain number of intervals before issuing a warning. For more information about monitor options, see BMC AMI Ops for IMS Online.
Metric | Indicates | Monitor | Monitor message | Recommended monitor values |
|---|---|---|---|---|
