Metrics for resource performance in Azure - Mini Project: Build & Apply

Metrics for resource performance

📖 Scenario: You are managing cloud resources in Microsoft Azure. To keep your resources healthy and efficient, you want to collect performance metrics like CPU usage and memory usage.This project will guide you to create a simple Azure Monitor metrics query to check resource performance.

🎯 Goal: Build an Azure Monitor metrics query that retrieves CPU and memory usage metrics for a specific virtual machine resource.

📋 What You'll Learn

Create a variable with the resource ID of the virtual machine

Define a time range for the metrics query

Write a metrics query to get CPU and memory usage

Configure the query to return average values

💡 Why This Matters

🌍 Real World

Monitoring cloud resources is essential to ensure they run efficiently and to detect problems early. Azure Monitor metrics help track resource health and performance.

💼 Career

Cloud engineers and administrators use metrics queries to analyze resource usage and optimize costs and performance.

1

Set the resource ID variable

Create a variable called resource_id and set it to the exact string "/subscriptions/12345678-1234-1234-1234-123456789abc/resourceGroups/MyResourceGroup/providers/Microsoft.Compute/virtualMachines/MyVM".

Azure

# Your code here

Need a hint?

The resource ID is a long string that uniquely identifies your VM in Azure.

2

Define the time range for metrics

Create a variable called time_range and set it to the string "PT1H" which means the last 1 hour.

Azure

resource_id = "/subscriptions/12345678-1234-1234-1234-123456789abc/resourceGroups/MyResourceGroup/providers/Microsoft.Compute/virtualMachines/MyVM"
# Your code here

Need a hint?

Use ISO 8601 duration format for the time range.

3

Write the metrics query

Create a variable called metrics_query and set it to the string "metrics?timespan=PT1H&metricnames=Percentage CPU,Available Memory Bytes&aggregation=Average" to query average CPU and memory usage for the last hour.

Azure

resource_id = "/subscriptions/12345678-1234-1234-1234-123456789abc/resourceGroups/MyResourceGroup/providers/Microsoft.Compute/virtualMachines/MyVM"
time_range = "PT1H"
# Your code here

Need a hint?

The query string includes timespan, metric names, and aggregation type.

4

Complete the Azure Monitor metrics request URL

Create a variable called request_url that combines resource_id and metrics_query with a slash between them.

Azure

resource_id = "/subscriptions/12345678-1234-1234-1234-123456789abc/resourceGroups/MyResourceGroup/providers/Microsoft.Compute/virtualMachines/MyVM"
time_range = "PT1H"
metrics_query = "metrics?timespan=PT1H&metricnames=Percentage CPU,Available Memory Bytes&aggregation=Average"
# Your code here

Need a hint?

Use string concatenation with a slash to build the full request URL.
