    At least by documentation its required on the following notes:

     
    Note 1 - https://docs.microsoft.com/en-us/azure/azure-monitor/agents/gateway
    The computer that runs the Log Analytics gateway requires the Log Analytics Windows agent to identify the service endpoints that the gateway needs to communicate with. The agent also needs to direct the gateway to report to the same workspaces that the agents or Operations Manager management group behind the gateway are configured with. This configuration allows the gateway and the agent to communicate with their assigned workspace.
    Note 2 - https://docs.microsoft.com/en-us/services-hub/health/log-analytics-gateway

    It is required to install the Microsoft Monitoring Agent on the Log Analytics Gateway and configure it with the same log analytics workspace that you will configure on the data collection machine.

    Sometimes without all the pre-requirements stuff works when it shouldn't :lol:

Hi, thanks for the repsonse. All servers are on prem. The gateway box is Server 2019 so doesnt have the Management Agent installed, I just ran the script from azure that turns it on (I believe its already has the functionality. ) So it was working for a bit, then failed for some reason. I came to a loose end and installed the management agent and it works.... Bizarre.
