A company has a Microsoft Azure HDInsight solution that uses different cluster types to process and analyze data. Operations are continuous. Reports indicate slowdowns during a specific time window…

While Azure Log Analytics collects HDInsight logs, formulating and running complex log search queries to diagnose specific performance issues in real-time may take longer than using Ambari's dedicated performance dashboards.

The Ambari REST API and its associated web UI provide comprehensive, real-time monitoring of HDInsight cluster services, metrics, and alerts, enabling rapid identification of performance bottlenecks and root causes of slowdowns.

Azure Monitor Metrics offers high-level insights for HDInsight but may lack the granular, application-specific details available through Ambari needed for deep troubleshooting of internal cluster slowdowns.

The HDInsight .NET SDK is for programmatic management of clusters, not primarily for interactive, real-time performance monitoring and issue diagnosis.

An Azure Log Analytics alert rule query is designed for proactive notifications when conditions are met, not for interactive, in-depth troubleshooting and tracking down the root cause of an ongoing performance issue.
