# Agentless & System Metrics

This [Agentless Approach](/manual/features/other-features/agentless-monitoring.md) 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="/pages/ucW3vLylxbehbTpefoYg" %}
[system\_stats](/manual/getting-started/postgresql-clusters/extensions/system_stats.md)
{% 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 %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.datasentinel.io/manual/features/tips-and-hints/agentless-and-system-metrics.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
