Although this chapter deals mostly with monitoring and logging, knowing the Kusto Query Language (KQL) might come in handy when implementing solutions.
KQL is a query language used to query, analyze, and visualize large datasets stored in Azure Data Explorer, Azure Monitor, Microsoft Sentinel, and Application Insights. KQL is a powerful language that allows you to perform various operations on your data, including filtering, aggregating, joining, and visualizing it.
