Chapter 5: Using the Kusto Query Language (KQL)

The Kusto Query Language (KQL) is a plain-text, read-only language that is used to query data stored in Azure Log Analytics workspaces. Much like SQL, it utilizes a hierarchy of entities that starts with databases, then tables, and finally columns. In this chapter, we will only concern ourselves with the table and column levels.

In this chapter, you will learn about a few of the many KQL commands that you can use to query your logs.

In this chapter, we will cover the following topics:

  • How to test your KQL queries
  • How to query a table
  • How to limit how many rows are returned
  • How to limit how many columns are returned
  • How to perform a query across multiple tables
  • How to graphically view the results
