Based on the following KQL query, I am trying to render two lines based on Type (either AADNonInteractiveUserSignInLogs or BehaviorAnalytics):1. The query below is giving this error: 'extend' operator: Failed to resolve scalar expression named 'traces'. The idea is to do a count of all log messages that start with 'message prefix' that appear between 'start message' and 'end message'. Here is the query: | where message == 'start message'. | project event = 'START', message, timestamp.The first thing to do is set the following properties to ensure that you're reading from the beginning of the stream in your queries: SET 'auto.offset.reset' = 'earliest'; Time to merge the individual streams into one big one. To do that, we'll use insert into.

Built-in Functions useful for Incident Response. Not unlike other large-data or database query languages, KQL allows you to: filter your data (with ‘where’ clauses); present your data (with either ‘project’ or ‘render’ clauses); and. aggregate your data (with ‘summarize’ clauses).

let is used for Ad-Hoc definitions, in a query's scope. Your code does not contain a query, only a let statement.

Therefore, the Azure Sentinel version avoids the state machine and is much simpler to build and maintain.

Like real tables, views organize data with rows and columns, and participate in tasks that involve wildcard table name resolution, such as union * and search * scenarios. However, unlike real tables, views don't maintain dedicated data storage.

Solution #2: Handle duplicate rows during query. Another option is to filter out the duplicate rows in the data during query.
