Question

Difficulty: MediumAzure Monitor and Log Analytics

An administrator needs to monitor the CPU utilization of an Azure virtual machine in real time and configure an automated alert to trigger if the utilization exceeds 90%90\%. The administrator asserts that Azure Service Health must be used to configure this CPU utilization alert. Is this assertion true or false?

Answer: Answer

Answer

The assertion is false because Azure Monitor Metrics, rather than Azure Service Health, is the service used to track individual resource metrics (like CPU utilization) and configure corresponding alert rules.
Azure Monitor is the service used to collect, analyze, and act on telemetry data (including CPU utilization metrics) from your Azure resources, whereas Azure Service Health monitors the health of Azure services and regions.

Step-by-Step Solution

1
Identify the monitoring requirement.
The requirement is to monitor a specific resource-level metric (virtual machine CPU utilization) in real time and trigger an alert.
To choose the correct tool, we must determine if it is a resource-level metric or an Azure-wide service health event.
2
Evaluate Azure Service Health.
Azure Service Health provides information about Azure service outages, planned maintenance, and other advisories impacting services globally or regionally.
This helps determine if Azure Service Health fits the requirement.
3
Evaluate Azure Monitor.
Azure Monitor collects and analyzes telemetry data, including resource metrics like CPU utilization, and supports metric alerts.
This identifies the correct service for resource-level alerts.
