Discovery events

Discovery events are created during the discovery process. They show the progress of agents, stitchers, and finders. These events are sent to and stored in Tivoli Netcool/OMNIbus and can be viewed using the Web GUI.

During the data collection and processing phases of discovery, stitchers including AgentStatus, FinderStatus, and CreateStchTimeEventwrite events to the disco.events table. The DiscoEventProcessing stitcher responds to an insert into the disco.events table and creates and sends the appropriate event to the probe for Tivoli Netcool/OMNIbus, nco_p_ncpmonitor, which then forwards the event to the ObjectServer.

You can configure your own discovery events by writing a stitcher to detect the event and write that event data to the disco.events table.

To enable the built-in discovery events, click the Discovery Events tab in the Discovery Configuration GUI and enable the events that you want:

EnableDiscoveryEvents

Enable or disable all discovery events.

EnableProcessEvents

EnableStitcherTimeEvents

Enable events that indicate possible configuration issues, including the following:

• An IP address discovery seed did not respond.
• An IP address discovery seed was not in scope.
• An IP address discovery seed was discovered but had no SNMP access.
• A device had SNMP access but on interface data.
• A device has no connectivity information.
