Schedule 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 schedule a discovery to run daily or weekly.

Note: You can run a scheduled discovery at any time by selecting a discovery profile and clicking Run. However, you cannot initiate an on-demand discovery for a discovery profile while a scheduled discovery for the discovery profile is in progress.

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.)

To run a discovery as the administrator, configure Data Collector for the Default Tenant domain before scheduling 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. Do one of the following steps:
   • Select an existing discovery profile that you want to schedule a discovery for and click Edit.

     The Edit Discovery Profile page opens.

   • Click New to create a discovery profile that you want to schedule a discovery for.

     The Discovery Profiles dialog opens.

3. To create a schedule for when you want this discovery profile to run, do one of the following steps:
   • To create a daily schedule, select Run Daily from the Scheduling Interval drop-down box and then select the time when you want the Discovery to begin each day.
   • To create a weekly schedule, select Run Weekly from the Scheduling interval drop-down box, select each day when you want the discovery to run, and select a time when you want the discovery to begin.

   Note: Select None from the Scheduling drop-down box to remove a schedule.

4. Click Save.

   When the discovery is scheduled, the State column for the discovery profile indicates 'SCHEDULED' and the next scheduled run time is displayed.

   When the scheduled 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.

   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 begin synchronizing with CA Performance Center. When the synchronization is complete, the discovered devices and components appear in the Inventory tab in CA Performance Center.

5. (Optional) To synchronize discovered devices and 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.
