# Prometheus

> Query metrics from Prometheus for performance analysis and capacity planning.

Connect Prometheus to let Foggy query your metrics during investigations — CPU usage, memory consumption, request rates, latency percentiles, and more.

## What Foggy can do

| Tool        | Description                                             |
| ----------- | ------------------------------------------------------- |
| **Metrics** | Execute PromQL queries against your Prometheus instance |

## Setup

Go to **Connectors** → **Add Connector** → **Prometheus** and fill in the form.

| Field    | Required | Description                                                             |
| -------- | -------- | ----------------------------------------------------------------------- |
| **Name** | Yes      | A label for this connector (e.g. "Production Prometheus")               |
| **Host** | Yes      | Your Prometheus instance URL (e.g. `https://prometheus.my-company.com`) |

<Note>
  Prometheus typically doesn't require authentication for read access. If your instance is behind an auth proxy, configure access at the network level.
</Note>

<Info>
  Foggy uses **read-only access**. Your data is never modified.
