I recently had an issue with a host that was already months ago added to Dynatrace, but needed to be readded. I didn’t show up in the OneAgent deployment status screen.
Normally, I would be successful by restarting the OneAgent service on Dynatrace on the host I wanted to add.
However, this time it wasn’t working. As a result, I did reinstall the OneAgent client. Unfortunately, that also didn’t resolve the issue.
Finally, I found the problem. In “Settings > Monitoring > Monitoring overview > Host,” monitoring was deactivated, which prevented it from showing up in the OneAgent deployment status.
Once I enabled it, it did show up without any issues on the Deployment status, OneAgent deployment page. You can see in the print screen host 0, but I couldn’t show you a print screen of the actual case. This was the first time it occurred to me. Hope this helps also you. 👍
