Azure ARM template schema/documentation for setting up alerts on Database Pools

I can’t find the documentation for the name of events/metrics that can be defined through ARM template to set up alerts on a SQL Elastic Database Pool. For example, I am guessing "EdtuPercentage" is the logical name for that metric but would like to know where to look it up. I can’t find alerts created on the portal on the ARM Explorer either. I appreciate any help!

To find a list of all the applicable/available metrics that can be set on a particular resource, there is a powerShell Command. You can use this powershell command to get a list of all such metrics with their logical names.

Get-AzureRmMetricDefinition

For example, if you want to lookup for a list of metrics for alerts for your elastic pool, you can simple use this command,

Get-AzureRmMetricDefinition -ResourceId "ElasticPoolResourceId"

You can provide the resourceID of your elastic Pool as a paramter here. And it will give you a list of all the applicable metrics for setting up alerts.

Hope this helps!
