This displays the name of the node, when the unmanage action begins, when it ends, the time the unmanage action was completed, and the name of the person in human readable form. You will need to acquire a list of Solarwinds users first. The code for that is at the bottom of the query
Solarwinds doesn't have extra tables in the database to allow human readable names to accounts so unmanage actions are shown as Active Directory accounts. In our organization these read like this DomainName\user2868732 These require effort to track down to a specific person. The query allows you to add all of the names in human readable form. It takes some effort to add them but once done the Case Statement can be ported to other scripts.
Can be added as either a custom query widget or as a report
