You develop data engineering solutions for a company.
A project requires the deployment of resources to Microsoft Azure for batch data processing on Azure HDInsight. Batch processing will run daily and must:
✑ Scale to minimize costs
✑ Be monitored for cluster performance
You need to recommend a tool that will monitor clusters and provide information to suggest how to scale.
Solution: Monitor clusters by using Azure Log Analytics and HDInsight cluster management solutions.

A. Yes
B. No

Show Suggested Answer

Suggested Answer: A 🗳️
HDInsight provides cluster-specific management solutions that you can add for Azure Monitor logs. Management solutions add functionality to Azure Monitor logs, providing additional data and analysis tools. These solutions collect important performance metrics from your HDInsight clusters and provide the tools to search the metrics. These solutions also provide visualizations and dashboards for most cluster types supported in HDInsight. By using the metrics that you collect with the solution, you can create custom monitoring rules and alerts.

I agree. The article suggests that Ambari should be used to check the cluster load (and therefore when to scale)

Is the solution to identify (a) Tool that will monitor clusters and provide information to suggest how to scale. ( Or) (b) Just solution to Monitor cluster load using the Ambari Web UI. if it is only for Monitoring it should be option b which is Ambari. The question is confusing me. Can anyone give clarification when to opt Ambari and When to go with "Azure Log Analytics" and "HDInsight cluster management solutions" ??
