 [Azure Monitor](/azure/azure-monitor/overview) collects and aggregates metrics and logs from every component of your system to monitor availability, performance, and resilience, and notify you of issues affecting your system. You can use the Azure portal, PowerShell, Azure CLI, REST API, or client libraries to set up and view monitoring data.

 - [Metrics explorer](/azure/azure-monitor/essentials/metrics-getting-started) allows you to view and analyze metrics for Azure resources.
 
 - [Log Analytics](logs/log-analytics-overview.md) allows you to query and analyze log data using the [Kusto query language (KQL)](/azure/data-explorer/kusto/query). For more information, see [Get started with log queries in Azure Monitor](/azure/azure-monitor/logs/get-started-queries).
 
 - The [activity log](/azure/azure-monitor/essentials/activity-log) has a user interface in the Azure portal for viewing and basic searches. To do more in-depth analysis, route the data to Azure Monitor logs and run more complex queries in Log Analytics.
