 Azure Monitor Agent (AMA) collects monitoring data from the guest operating system of Azure and hybrid virtual machines and delivers it to Azure Monitor for use by features, insights, and other services, such as [Microsoft Sentinel](../../sentintel/../sentinel/overview.md) and [Microsoft Defender for Cloud](../../defender-for-cloud/defender-for-cloud-introduction.md). Azure Monitor Agent replaces all of Azure Monitor's legacy monitoring agents. This article provides an overview of Azure Monitor Agent's capabilities and supported use cases.

+- **Cost savings** by [using data collection rules](data-collection-rule-azure-monitor-agent.md):
+  - Enables targeted and granular data collection for a machine or subset(s) of machines, as compared to the "all or nothing" approach of legacy agents.
+  - Allows filtering rules and data transformations to reduce the overall data volume being uploaded, thus lowering ingestion and storage costs significantly  
+- **Simpler management** including efficient troubleshooting:
+  - Supports data uploads multiple destinations (multiple Log Analytics workspaces, i.e. *multihoming* on Windows and Linux) including cross-region and cross-tenant data collection (using Azure LightHouse)
+  - Centralized, agent configuration "in the cloud" for enterprise scale throughout the data collection lifecycle, from onboarding to deployment to updates and changes over time. 
+  - Any change(s) in configuration is rolled out to all agents automatically, without requiring a client side deployment
+  - Greater transparency and control of more capabilities and services, such as Microsoft Sentinel, Defender for Cloud, and VM Insights.
+- **Security and Performance**
+  - Enhanced security through Managed Identity and Azure Active Directory (Azure AD) tokens (for clients)
+  - Higher event throughput that is 25% better than the legacy Log Analytics (MMA/OMS) agents.
+- **A single agent** that servers all data collection needs across servers and client devices running Windows 10 or 11. A single agent is the goal, although Azure Monitor Agent currently converges with the Log Analytics agents.
