Managing Interfaces › How to Poll Critical Interfaces Faster than Noncritical Interfaces › View Monitored Devices to Verify Results

View Monitored Devices to Verify Results

After you set up your monitoring profiles, review the monitored devices and the Filter report to verify that only your critical devices are polled at the higher rate. This information helps you to see information in context, such as which monitoring profiles are being used to poll device components. Verifying the results can help you identify any necessary adjustments to help you achieve the polling results that you want.

Note: Monitored devices are manageable devices and pingable (accessible but not manageable). Inaccessible devices are not monitored devices. Components of monitored devices can be viewed from the Polled Metric Families tab.

Follow these steps:

1. Run an on-demand discovery.

   Note: If your discovery profile runs automatically, you can wait for the next scheduled discovery. For more information about managing discovery, see the Data Aggregator Administrator Guide.

2. Click Monitored Devices from the Monitored Inventory menu for a Data Aggregator data source.
3. Select one of these options from the drop-down list to locate one of your aggregation switch devices in the corresponding tree view:
   • Device by Collection—Your devices appear under the All Switches device collection.
   • Device by Monitoring Profile—Your critical interfaces appear under Devices under the Uplink Interfaces monitoring profile.

   Note: Alternatively, select the Search tab to search by host name, device name, or IP address. You can enter a partial name or IP address to return a list of devices that contain that partial match. Wildcards and regular expressions are not supported.

   The Polled Metric Families tab shows the consolidated monitoring profiles that are associated with the switch device. Devices have only one consolidated monitoring profile. Each consolidated monitoring profile lists every metric family to poll on the device and whether the device supports the metric family.

4. Select the Interface metric family.

   The Components table for the Interfaces metric family shows one of the following polling statuses for the discovered Interface components:

   Active

   Indicates that the component is being polled.

   Inactive

   Indicates that polling has stopped on the component because the metric family is no longer monitored for the device.

   Retired

   Indicates that the component no longer exists on the physical device. Polling is stopped on the component. You can view historical data for reporting purposes. 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.

   Filtered (interface components only)

   Indicates that the component does not pass the filter criteria and polling on the component is stopped.

   Note: Filtered interfaces are not displayed in CA Performance Center dashboards and data views.

5. (Optional) Select the Interface metric family and click Update Metric Family.

   Data Aggregator reconfigures components for any configuration updates. For example, if you add a disk drive on a server, you can use the Update Metric Family button to rediscover the configuration update. The configuration update creates a disk component.

6. Click the Filter Report tab and follow these steps:
   1. Look at the filters on each of the other Interface monitoring profiles to see if they are monitoring the same device collection that you want to filter.
   2. Remove any relationships between other Interface monitoring profiles and device collections that will block your filter criteria. For example, if your new Interface monitoring profile is associated with the All Routers device collection, remove the relationship between other Interface monitoring profiles and the All Routers device collection.
   3. Run another discovery and review the updated Filter report to verify that the new filter criteria is active. If the Filter report shows that an unwanted monitoring profile was included, repeat the previous steps until you are monitoring only the interfaces that you want.

   The Filter Report tab shows which interface filter criteria have been used during component monitoring. The tab also shows a report of all of the interfaces that are identified on the device and whether they matched the specified filter criteria.

   Note: If you change the rules on a custom monitoring profile, the Interface Filter Criteria pane does not reflect those changes. If you disassociate the monitoring profile from a group, the Interface Filter Criteria pane does not reflect those changes. Rediscover the device to filter the interfaces that are based on the changes you made to the filter criteria and monitoring profile.
