Azure Monitor and Azure Data Explorer cross-service querying This experience enables you to query Azure Data Explorer in Azure Log Analytics/Application Insights tools (See more info here), and the ability to query Log Analytics/Application Insights from Azure Data Explorer tools to make cross resource queries. (See more info here.),
For example (querying Azure Data Explorer from Log Analytics):
Where the outer query is querying a table in the workspace, and then joining with another table in an Azure Data Explorer cluster (in this case, clustername=help, databasename=samples) by using a new "adx()" function, like how you can do the same to query another workspace from inside query text. Both experiences are in Public Preview.
