@Revanth Thavidishetty , Welcome to the Microsoft Q&A platform.

You can monitor your HDInsight cluster by sending metrics and logs to a Log Analytics workspace.

With Azure Monitor, you can

View and explore cluster-specific dashboards

Query and analyze OSS logs and metrics

View VM-level performance counters, such as Memory and CPU counters

Get notified about important events by setting Azure Monitor alerts

Monitor multiple clusters from the same Log Analytics workspace

Example: Once the logs are in Azure Monitor, you can create a new alerts based on the conditions required.

Hope this helps. Do let us know if you any further queries.

@PRADEEPCHEEKATLA-MSFT Thanks for the information. I am using the below query to get the yarn memory usage. metrics_resourcemanager_queue_root_CL | summarize AggregatedValue = avg(AvailableMB_d ) by bin(TimeGenerated, 10m) | where AggregatedValue > 90000

do you have any suggestion on the above query

@Revanth Thavidishetty , What are the suggestion required on the above query?

You can also use the logs view in your Log Analytics workspace to query the metrics and tables directly.

HDInsight clusters emit several workload-specific tables of logs, such as log_resourcemanager_CL, log_spark_CL, log_kafkaserver_CL, log_jupyter_CL, log_regionserver_CL, and log_hmaster_CL.

On the metrics side, clusters emit several metrics tables, including metrics_sparkapps_CL, metrics_resourcemanager_queue_root_CL, metrics_kafka_CL, and metrics_hmaster_CL. For more information, please see our documentation, Query Azure Monitor logs to monitor HDInsight clusters. and "Azure HDInsight monitoring".

Hope this helps.
