Microsoft Certified: Azure Administrator AssociateDeploy and manage Azure compute resourcesEasy
An Azure Virtual Machine (VM) running a critical application is experiencing intermittent performance issues. You suspect that the VM's disk I/O operations are bottlenecking the application. You need to identify the current disk performance metrics, specifically the Read Operations Per Second (IOPS) and Write Operations Per Second (IOPS) for the OS disk and data disks. Which Azure monitoring tool should you use to gather this information?
- AAzure Advisor
- BAzure Monitor Metrics
- CAzure Activity Log
- DAzure Network Watcher
Show answer & explanationAnswer & explanation
Correct answer: B. Azure Monitor Metrics
Azure Monitor Metrics collects numerical data from Azure resources, including detailed performance metrics for VM disks such as Read/Write IOPS, throughput, and latency.
Why the other options are wrong
- A. Azure Advisor provides personalized recommendations for best practices, not real-time performance metrics.
- C. Azure Activity Log records control-plane events (e.g., VM start/stop), not operational performance data like disk IOPS.
- D. Azure Network Watcher helps with network diagnostics and monitoring, not disk performance metrics.
Azure Monitor Metrics
A feature of Azure Monitor that collects numerical data from Azure resources into a time-series database. It is used to track the performance and health of resources.
- Collects numerical data (e.g., CPU %, disk IOPS)
- Provides near real-time insights
- Supports charting, alerting, and auto-scaling based on metrics
- Data retained for 93 days by default
