Discovery device history

The Devices related list in the Discovery Status form provides a summary list of all the devices scanned.

During a Discovery, the list tracks current and completed activity and displays an incremental scan counter. When Discovery is finished for a device, the final disposition is displayed in the Completed activity column. Successful Discoveries that result in updated or created CIs are highlighted in green. When device history or duplicate IP record is created, the classification_probe is also populated. To view the log entries for errors (such as connection failure) on a specific device, click the Details link in the Issues column.

Click the IP address of a device in this list for details about that device. The log results for that device are displayed in the list at the bottom of the form.

The following fields are available in this form:

Field	Input value
Source	The IP address of the device discovered.
Completed activity	Indicates the outcome of Discovery for this device or the last completed activity for a Discovery in progress, such as Identified CI. Successful outcomes are indicated in green.
Current activity	The current scanning activity for this device for a Discovery in progress, such as Updating CI.
CMDB CI	The name of this device as it appears in the CMDB.
Started	The number of device-specific probes run. This number does not include the universal probes, Shazzam and Ping, that run initially.
Completed	The number of sensor records created from the device-specific probes that were run.
Scan status	Shows the final scan count of a completed Discovery or an incremental scan counter for a Discovery in progress. For example, Scan 17 of 19.
Issues	Displays the number of issues encountered during Discovery of this device. Select the Discovery Log Related List to view these issues.
Fields that can be added by configuring the form:
DNS Names	Displays DNS names for each discovered device.

During different phases of Discovery, you may see different values in the Completed Activity field on a discovery_device_history record.

Value	When you might see this value	Meaning
Common examples
Alive, not active, not classified	After Shazzam	Device is responding, but it does not have any open (active) ports that we can run classification against.
Active	After Shazzam	Device has open (active) ports that we potentially can run classification against.
Classified	After Classification Probe	We were able to classify the device type and will be proceeding to the Identification stage.
Active, couldn’t classify	After Classification Probe	We were unable to classify the device type. Sometimes, this value will also include a reason for why we were unable to classify. For example, Active, couldn't classify: No WMI connection.
Created CI	After Identification Probe/Pattern or after Discovery - Device Complete Business Rule runs (for new CI)	New CI has been created based on identification results.
Identified CI	After Identification Probe/Pattern	Existing CI has been found based on identification results.
Identified, ignored extra IP	After Identification Probe/Pattern	Device has already been discovered via a different IP in same Discovery status.
Updated CI	After certain Exploration Probes/Patterns or after Discovery - Device Complete Business Rule runs (for existing CI)	CI has been updated with additional information.
Less common examples
Unclassified	After Shazzam (only for credential-less Discovery and the Discover value on the Discovery Schedule is set to IP Addresses)	For the credential-less Discovery of the target IP, we were unable to match to an existing CI on the instance.
Classified	After Shazzam (only for credential-less Discovery and the Discover value on the Discovery Schedule is set to IP Addresses)	For the credential-less Discovery of the target IP, we were able to match to an existing CI on the instance.
Active, Windows Cluster VIP	After Windows - Classify	Device is a Windows Cluster VIP and will be updated as such.
Classified, but not disabled	After Classification Probe	We made a match to a Classifier type, but the classifier itself is disabled.
Classified, couldn't identify	After Identification Probe/Pattern	Couldn’t create or match to existing CI record.
Identified, not updating CI	After Identification Probe/Pattern	We were able to properly identify a CI record, but we are choosing not to update the CI.

Any device that includes the following classes or one of its child classes will be displayed in the Discovery device history table.

• Computer [cmdb_ci_computer]
• Network Gear [cmdb_ci_netgear]
• PDU [cmdb_ci_pdu]
• Printer [cmdb_ci_printer]
• UPS [cmdb_ci_ups]

If there were issues, or if Discovery failed to complete, click the Details link to view the log records for the issue. The failure of any probe is considered an issue, even if the device was eventually classified properly and updated in the CMDB.

Address scan data

When Discovery scans for IP addresses only (without credentials or identifiers), no updates are made to the CMDB. All IP addresses discovered appear on this list, including multiple IPs on the same device. The results of IP address scans include slightly different information than the results of a CI scan. Since there is no CMDB activity associated with the IP address scan, the Completed activity column displays only the classification status.

Possible statuses are:

• Classified
• Unclassified
• Alive, not classified

For Classified devices, Discovery might identify the type of device in the Current activity column. For example, Network Gear might be classified as Cisco Network Gear, and a Computer might be classified as a Windows Computer.
