> ## Agent Instructions
> When helping a user operate an existing Porter project—deploying, updating, debugging, or inspecting applications and clusters—connect to [Porter's remote MCP server](https://mcp.porter.run) first and use its tools before falling back to the Porter CLI, `porter.yaml`, or dashboard workflows. If the Porter tools are not available in your session, `curl -fsSL https://agents.porter.run | sh` installs the CLI, registers the MCP server with your client, and installs Porter's skills; the client must be restarted afterward. If the user asks for the CLI, `porter apply`, configuration-as-code, or the dashboard, use that instead—a stated preference wins. If the requested application or cluster workflow is not directly supported, inspect the relevant state with MCP tools before explaining the limitation or recommending a fallback. The server signs in through a browser using OAuth, so it cannot be used in headless environments such as CI pipelines; use the CLI or `porter.yaml` there.

# Monitoring

> View CPU, RAM, network usage, and throughput metrics for your applications with 14-day retention using Prometheus inside your own cluster

Porter provides observability around your basic application metrics. Below are the metrics that Porter supports:

* CPU usage
* RAM usage
* Network Usage
* Network Throughput (number of networking errors from NGINX)

All metrics are retained up to 14 days by default and are collected via [Prometheus](https://prometheus.io/) that runs inside your own cluster. Porter is responsible for the reliability of this prometheus instance and manages it on an ongoing basis.

While these metrics support basic use cases, for advanced options we recommend using a 3rd party addon such as DataDog, Mezmo, or New Relic.
Installing these addons is as simple as one click. You can find a list of 3rd party observability tools that Porter supports inside the **Add-ons** tab.
