Querying ApplicationInsights

Devin,

If you're querying exclusively Application Insights, please use option 3 (querying from within Application Insights).

If you're querying a combination of Log Analytics and Application Insights, please use option #1 from within either the AI or LA portals. IntelliSense support is something high on our backlog, together with a better unification between the two services. Expect to see features around this in the coming months.

Option 2 should be considered outdated. I'd turn off the Application Insights connector to both avoid the schema confusion, as well as save yourself some costs from dual-ingesting the data. This feature was originally created as a stop-gap before we had cross-AI-and-LA queries available.
