Discovery Quality Scores

Discovery Quality Scores

The Discovery Quality Scores page provides users with an the ability to view the success of their discovery jobs on a granular level. Via the quality scores page, users can see each device that was discovered, the target IP it was discovered from (which is also a link to that job’s page), the job name, time stamps, and status of port check and auth. The Discovery Quality Scores page can be found from the main menu, Reporting -> Discovery Scores.
Discovery Quality Scores page

By default, discovered devices are sorted newest to oldest, most recently discovered listed first. Each device is shown on its own line, which offers information about how it was discovered including the target discovery IP (which also links back to each job’s ‘Quality Score Detail’ page) of the job that discovered it, the job name (links to the job’s config page), the job’s timestamps, and a red/green ‘at-a-glance’ view the discovery status. Green indicates discovery success, while red indicates there might have been an issue with that particular stat.

Clicking on any of the items in the “Discovery Targets” column will bring you to a “View Discovery Score” details page for that particular item:

Legacy Quality Scores

Discovery Quality Scores ‘v2’, discussed above, supersedes the original implementation of discovery quality scores. As of v15.14.00+, development will focus on the v2 implementation of discovery quality scores discussed above. Users who rely on the v1 quality score implementation can currently find the old discovery scores page in the reporting menu, called ‘Legacy Auto-discovery Scores’:
