Azure Monitor is enabled the moment that you create a new Azure subscription, and [Activity log](./essentials/platform-logs-overview.md) and platform [metrics](essentials/data-platform-metrics.md) are automatically collected. Create [diagnostic settings](essentials/diagnostic-settings.md) to collect more detailed information about the operation of your Azure resources, and add [monitoring solutions](insights/solutions.md) and [insights](./monitor-reference.md) to provide additional analysis on collected data for particular services.

You can connect your existing System Center Operations Manager management group to Azure Monitor to collect data from agents into Azure Monitor Logs. This allows you to use log queries and solution to analyze data collected from agents. You can also configure existing System Center Operations Manager agents to send data directly to Azure Monitor.

Azure Monitor collects data from a variety of sources including logs and metrics from Azure platform and resources, custom applications, and agents running on virtual machines. Other services such as Microsoft Defender for Cloud and Network Watcher collect data into a Log Analytics workspace so it can be analyzed with Azure Monitor data. You can also send custom data to Azure Monitor using the REST API for logs or metrics. See [Sources of monitoring data for Azure Monitor](agents/data-sources.md).

All log data collected by Azure Monitor is stored in a Log Analytics workspace. A workspace is essentially a container where log data is collected from a variety of sources.

Both on-premises machines and machines connected to other clouds are supported for servers today, once you have the Azure Arc agent installed. For purposes of running AMA and DCR, the ARC requirement comes at **no additional cost or resource consumption**, since the ARC agent is only used as an installation mechanism and you need not enable the paid management features if you don’t wish to use them.
