IMS metrics provided by views
The following metrics are available in the
MainView for IMS Online
views. For information about using this table, see How-to-use-the-metric-tables.
Before you create alarms based on these metrics, review the best practices for alarms in Manage-application-exceptions.
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.
