Connection Monitor XXX creation failed (Created with error)

Question

Hi

I have been trying to create a Connection Monitor on and off for a few months now for an ARC server. It always fails with Connection Monitor XXX creation failed and the deployment page show Created with error. It shows in the list of connection monitors but with a red * next to it and doesn't work. If I look in the activity monitor there is a failed "Create or update data collection rule" event and in the JSON for that it shows:

"statusMessage": "{"error":{"code":"InvalidPayload","message":"Data collection rule is invalid","details":[{"code":"InvalidOutputTable","target":"properties.dataFlows[0]","message":"Table for output stream 'Miicrosoft-NetworkMonitoring' is not available for destination 'NetworkWatcherLogAnalytics'."}]}}

I have tried different log analytic workspaces, disabling and enabling the network watcher for the region, reinstalling the VM extensions but I just can't seem to figure out what the issue is.

Regards

Hello @C5David ,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that you are trying to create a Connection Monitor for an ARC server but it always fails with Connection Monitor XXX creation failed and the deployment page shows Created with below error:

"statusMessage": "{"error":{"code":"InvalidPayload","message":"Data collection rule is invalid","details":[{"code":"InvalidOutputTable","target":"properties.dataFlows[0]","message":"Table for output stream 'Miicrosoft-NetworkMonitoring' is not available for destination 'NetworkWatcherLogAnalytics'."}]}}

To fix this issue, please enable NPM (Network Performance Monitor) solution on the Destination Log Analytics workspace following the below steps:

• Go to Network Watcher resource in Azure.
• Click on Network Performace Monitor blade under Monitoring.
• Click on Add NPM option (on the top)
• Select the subscription and workspace in which you want to enable the solution, and then select Create.

Refer: https://learn.microsoft.com/en-us/azure/network-watcher/connection-monitor-overview#enable-the-network-performance-monitor-solution-for-on-premises-machines

Once done, try creating the connection monitor. It should be successful.

Kindly let us know if the above helps or you need further assistance on this issue.
