What it does
Azure Monitor is Microsoft's platform for collecting and analyzing telemetry from Azure and on-premises services. It covers metrics, logs, traces, alerts, and Application Insights for application observability. Teams can use it to watch resource health, investigate a service issue, and notify or trigger a response; it does not repair the application automatically unless an operator connects an automation action.
Start by deciding what signal will reveal the problem: a resource metric, a log query, or application telemetry from Application Insights. Azure Monitor's documentation describes collecting and analyzing all three, then creating alert rules for metric, log, and other supported conditions. For a web service, a useful first check is to instrument the application with the documented Application Insights OpenTelemetry workflow and create one alert on an actionable failure or latency signal.
Alerts can notify a team or call an automated solution, but an alert is only the detection step. Use the associated metrics, logs, and traces to find where the request or resource failed, then make the fix in the service or its infrastructure. Start with a narrow alert and representative traffic; broad collection and noisy thresholds can increase both ingestion cost and alert fatigue.
Azure Monitor uses consumption-based, pay-as-you-go billing. Microsoft notes that charges vary by feature and usage, with log ingestion often a major component; exact total cost depends on the workspace, volume, and retention selected. The platform also covers Azure and on-premises resources, so a team should map its data sources and retention needs before enabling collection everywhere.
Strengths
- The documentation covers metrics, logs, traces, alerts, and application observability in one platform.
- Application Insights provides a documented OpenTelemetry path for application telemetry.
- Alerts can notify responders or call automated solutions when a condition is met.
Watch out for
- The service spans multiple telemetry features with different usage charges, so cost requires attention to ingestion and retention.
- An alert detects a condition; diagnosing and correcting the application remains a separate task.
- Teams need to configure data collection and alert rules that fit their actual environment rather than relying on defaults alone.
Best for
- Teams operating applications and resources in Azure or on-premises environments.
- Operators who want resource metrics and application telemetry connected to alert workflows.
- Organizations able to manage data ingestion, retention, and consumption-based costs.
