When querying metrics using Azure Monitor Query, specifics filters have to be used instead of getting data from all dimensions #20329
Description
Whenever querying metrics with Azure Monitor Query, the metric query must contain filters with specific dimensions to get accurate information.
When using the Portal there is no need of doing filtering 1 by 1, since the user can either apply a filter or use the split feature or both to see the multiple results from different dimensions.
Supporting splitting by <dimension_name> would make things easier since for example, in my team's current project the dimension is called process_id and there are more than 25 different process ids that I should know the name beforehand to query them 1 by 1 with multiple filters.
Adding the split feature would make things easier:
- the user wouldn't need to know the dimension names beforehand
- one query would replace one query per dimension name
