Run On Demand Discoveries

Inventory discovery is the process through which devices are discovered in your network, which is based on information you add to discovery profiles. You can run an on-demand discovery.

Attempts to discover devices are made through SNMP and ICMP protocols. If a device does not respond to SNMP with the SNMPv1/SNMPv2c or SNMPv3 profiles you created but does respond to ICMP, a pingable device is created. (SNMP profiles are created using either the CA Performance Center user interface or the CA Performance Center REST web services.)

This task can be done as either the tenant administrator or as the administrator. To run a discovery as the administrator, configure Data Collector for the Default Tenant domain before running the discovery.

Note: For more information about creating SNMP profiles and synchronizing them with Data Aggregator, see the CA Performance Center Administrator Guide and the CA Performance Center REST Web Services Guide.

Follow these steps:

1. Navigate to the list of discovery profiles in CA Performance Center.
2. Select one or more discovery profiles that you want to run a discovery on and click Run.

   Note: You can only run a discovery on a discovery profile that has a state of 'READY'.

   A confirmation dialog opens.

3. Click Yes.

   The discovery starts, the State column for the selected discovery profiles indicates 'RUNNING', and the Last Run Time column is updated with the time when the discovery starts.

   Note: To trigger the Percentage Complete column to update while discovery is running, click Refresh.

   A confirmation dialog opens.

4. Click OK.

   Discovered devices are added to device collections, which initiates component monitoring and polling. You are returned to the Discovery Profile page.

   If discovery hangs for more than 10 minutes, it is aborted. A discovery is considered to be hanging when no new devices are discovered within 10 minutes and the state for the selected discovery profiles have not changed within 10 minutes. An audit event is generated on the Data Aggregator device.

   The State column for the selected discovery profiles indicates 'FAILURE' if no devices were discovered successfully, or 'PARTIAL_FAILURE' if at least one device was discovered successfully.

   The discovered devices and monitored components can take up to 5 minutes to synchronize with CA Performance Center. When the synchronization is complete, the discovered devices and monitored components appear in the Inventory tab in CA Performance Center.

5. (Optional) To synchronize discovered devices and monitored components immediately with CA Performance Center, perform the following steps:
   1. Select Admin, Data Source Settings, and click a Data Aggregator data source.
   2. Click Data Aggregator from the System Status menu.
   3. Select Data Aggregator and click the Resynch button.
