Node captions are automatically set when a node is added to Orion, then it is never automatically updated ever again - How Caption field for nodes is determined - SolarWinds Worldwide, LLC. Help and Support
In the real world, servers get renamed and teams don't always update Orion. Please add a feature request to expand options for caption handling...
1) Never automatically update node caption (current behavior)
2) Never automatically update node caption if caption was manually set
3) Always automatically update caption to match DNS or sysname with exclusion option for nodes where caption was manually set
