Microsoft Monitoring Agent Setup Error

New Contributor

I am getting an error while trying to install the agent on two servers... I have one working just fine.


Invalid Azure Log Analytics Configuration

Unknown error was encountered during setup.  Please check log file: (%temp%\MonitoringAgent.log).


Any suggestions?

Here is the log file I inserted 1234567890 into spots tied to my account...

Ill answer my own here.... after messing with it for a day.... If you do not check the Connect the agent to Azure Log Analytics (OMS) on the initial install then go to the control panel after and set it up everything works out.

Carlos, if you haven't already figured this out, double check your internet connection. The agent requires internet connection to connect to the Azure portal, so you need to configure the Proxy settings.
For me with the same error, I had to install it without trying to make the connection to Log Analytics workspace. After the installation, then going to the control panel for its setting, I then was able to successfully add / connect to the Log Analytics workspace.
worked like a charm
