What is KQL and where can I use these queries?

KQL (Kusto Query Language) is the query language used across Azure Monitor Logs, Log Analytics, Application Insights, Azure Data Explorer, and Microsoft Sentinel. Queries generated by this tool work in any of these services.

Do I need an Azure subscription to use this tool?

No. This tool generates KQL query strings in your browser. You copy the generated query and run it in your Azure environment. The tool itself does not connect to Azure.

Does this support custom log tables?

The pre-built templates target standard Azure Monitor tables like Heartbeat, Perf, AzureActivity, and AppRequests. You can modify the generated queries to reference custom log tables in your workspace.

About This Tool

The Azure Monitor Query Builder helps you construct KQL (Kusto Query Language) queries for Azure Monitor with pre-built templates and guided field selection. KQL is powerful but has a learning curve, and this tool bridges the gap by letting you pick common scenarios like VM performance, App Service errors, or network metrics and customize them into production-ready queries. The generated queries can be pasted directly into Azure Monitor Logs, Log Analytics workspaces, or Application Insights.

When to Use This Tool

•Build KQL queries to analyze Azure VM CPU, memory, and disk metrics during performance investigations.
•Generate Application Insights queries to track request failures, dependency latencies, and exception rates.
•Create queries for Azure Activity Log to audit resource modifications, RBAC changes, and deployment events.
•Build time-series aggregation queries for operational dashboards in Azure Monitor Workbooks.
