Update Device Reconfiguration Automatically

Reconfiguration changes to a discovered device can affect the metric families that are associated with the device. The device reconfiguration can be set to update automatically in the monitoring profile the metric families are assigned to, which applies to any metric families that the monitoring profile includes. This option is set by default when you create a custom monitoring profile, but it can also be edited at any time. This procedure tells you how to set the Automatically Update Metric Families option in an existing custom monitoring profile if it has been previously deselected.

When the metric family is updated, Data Aggregator has an accurate representation of the device configuration. Reports that you generate reflect accurate information.

Follow these steps:

1. Navigate to the list of all monitoring profiles.
2. Select the monitoring profile that you want to update automatically and click Edit.
3. Select Enable Change Detection and then do the following steps:
   • Set the Change Detection Settings, Rate to a value that is greater than zero.

     Note: Consider how frequently the metric family is likely to change, and how many devices the monitoring profile is applied to. Avoid setting change detection rates that are more frequent than necessary.

   • Select Automatically Update Metric Families.
   • Click Save.

   When you make a configuration change to a device associated with this monitoring profile, the device configuration is updated automatically.

   When a device configuration is updated, Data Aggregator does the following steps:

   • Generates an event on the monitored device.
   • Identifies new components and creates them.
   • Identifies components that are no longer present and retires them.

     Note: By default, retired components are not synchronized with CA Performance Center. To enable this option, select the Synchronize retired items checkbox on the Edit Data Source dialog on the Manage Data Sources page in CA Performance Center.

   • Identifies existing components that have changed from a previous discovery. The Name column changes, if applicable.

     Note: Historical data is accessible and can be reported on.
