View Discovery Results

You can view a summary of the number of new pingable (ICMP) and manageable (SNMP) devices that were discovered during a specific discovery instance. You can also view specific details about these discovered devices, including the IP address, model, type, vendor name, location, and the protocols that were used.

A discovery result can also indicate that existing devices were found. The same or a different discovery profile discovered these existing devices previously. To view existing devices, use the Unchanged filter. Existing devices that show different IP addresses indicate that the devices were previously discovered and are being monitored with a different IP address.

This behavior is common and expected, as many devices can respond to multiple IP addresses. Data Aggregator maintains the full set of IP addresses for each device and contributes them all to CA Performance Center.

Follow these steps:

1. View a list of discovery profiles.
2. Select a discovery profile for which you want to view discovery results and click the History button.

   Note: The History button is disabled when you select a discovery profile for which a discovery has not been run.

3. Select a Discovery instance, if applicable.
4. (Optional) Filter the Discovered Devices table by doing one of the following options:
   • Filter by device type by selecting which device types you want displayed from the Device Type Filter list and clicking Apply.
   • Filter by the state of the discovered devices by selecting which states you want displayed from the State list and clicking Apply.
   • Filter by device type and state by selecting from the Device Type Filter list and the State list and clicking Apply.

   The discovery results appear in the Discovered Devices table. The SNMP Profile column shows the highest ranked SNMP profile the device responded to.

   Specifically, the State column indicates one of the following states:

   New

   Indicates a device that was discovered for the first time when this discovery profile was run.

   Changed

   Indicates that a device type has changed from a previous discovery. For example, a previously discovered pingable device is now discovered as a manageable device. Or a previously manageable device with the device type of “Switch” has now changed to the device type of “Router”, and so on. Devices with only attribute changes, such as hostname, system description, and so on, are not classified as Changed.

   Unchanged

   Indicates that existing devices have not changed. Existing devices with only attribute changes are classified as Unchanged also.

   Deleted

   Indicates that the device was deleted from Data Aggregator since a discovery was run.

   Note: If an individual discovered device fails to be recognized as pingable or manageable, its state indicates Unreachable. However, Data Aggregator does not report unreachable devices that are found in an IP range.
