# Agentless & System Metrics This [Agentless Approach](https://docs.datasentinel.io/manual/features/other-features/agentless-monitoring) simplifies the setup and reduces the overhead on your systems. However, a common misconception is that agentless monitoring limits the ability to gather detailed system metrics. To address this and enhance your monitoring capabilities, Datasentinel supports the integration of the `system_stats` extension. {% content-ref url="../../getting-started/postgresql-clusters/extensions/system\_stats" %} [system\_stats](https://docs.datasentinel.io/manual/getting-started/postgresql-clusters/extensions/system_stats) {% endcontent-ref %} When installed on your PostgreSQL server, this extension empowers Datasentinel to collect a wide range of system metrics. This includes crucial information like CPU usage, memory consumption, disk I/O, and more, providing a deeper insight into the server's performance. {% hint style="info" %} Once the metrics are collected, they are displayed in an identical format across both collection methods: agent-based or agentless. {% endhint %}
