I have configured Application insights from API Management, Inside App Insights i have configured Alert rules, whenever there is a error, Alert will be triggered & a webhook will be invoked with the alert details.

In Query i have added customdimensions["Request-Body"] and customdimensions["Response-Body"], which is not getting listed in split-dimension dropdown,

the fileds which are listed in dropdown only comes in webhook, but i need customdimensions["Request-Body"] and customdimensions["Response-Body"] as well, how to get it

    Hi there,

    The customdimension column is dynamic, so your query "extends" the schema, not adds

    If you want to leverage dimensions in alerting, convert it to string first
