The Issue
I had installed the “VMware vRealize Operations Management Pack for Horizon 1.2” into my vROPs instance, and tried to connect my Horizon instance, instantly hitting the helpful error message of:
Failed to Test adapter instance. Reason - Unknown Error. Please contact support team
Obviously, I’d probably done something wrong, but I didn’t want to just call support for help!
Finding the Cause
So off to find the logs.
- In the Administration Tab, scroll down on the left-hand navigation pane to Support
- Select Logs
- Expand the following folders > /{IP}-MASTER >COLLECTOR>adapters
- Select the correct folder for your adapter type
- Click the Log > Click the Blue Go button to load the log
The Fix
As we can see in this environment the issue was quite simple, an illegal character, turns out there was a space in my FQDN.
I correct this and success!
The main reason for this quick blog post, was to show how to find the logs for the adapters so you can troubleshoot things yourself first.
