Template variables
Instead of hard-coding values for fields like resource group or resource name in your queries, you can use variables in their place to create more interactive, dynamic, and reusable dashboards.
Check out the Templating documentation for an introduction to the templating feature and the different types of template variables.
The Azure Monitor data source provides the following queries you can specify in the Query field in the Variable edit view
Any Log Analytics KQL query that returns a single list of values can also be used in the Query field. For example:
Example of a time series query using variables:
Perf
| where ObjectName == "$object" and CounterName == "$metric"
| where TimeGenerated >= $__timeFrom() and TimeGenerated <= $__timeTo()
| where $__contains(Computer, $computer)
| summarize avg(CounterValue) by bin(TimeGenerated, $__interval), Computer
| order by TimeGenerated asc
