d8ea041c56 docs: introduce versioned docs and migrate to fuma (#11166)
## Todos for release

- [x] Configure Env in docs project on vercel
- [x] Configure Root Path in the docs project on vercel
- [ ] Remove old CSP https://github.com/zitadel/website/pull/1592

## What we did

This pull request migrates the project documentation from the old
`docs/` directory to the new `apps/docs/` directory, introduces a new
documentation system built with Next.js and Fumadocs, and updates all
relevant references, configuration files, and documentation to reflect
this change. It also adds new configuration and ignore files for the new
documentation app, updates CI and linting to exclude the new docs from
certain checks, and revises the contributing guidelines accordingly.

**Documentation System Migration and New Docs App**

* Migrated all documentation from `docs/` to `apps/docs/`, and updated
all references in `README.md`, `CONTRIBUTING.md`, and other files to
point to the new location.

and a comprehensive `README.md` with development and contribution
instructions.

**Configuration and Tooling Updates**

* Updated `.github/workflows/codeql.yml`, `.golangci.yaml`, and
`.github/dependabot.yml` to properly handle the new docs app: excluded
`apps/docs` from certain checks, added npm dependency updates for the
docs app, and excluded generated content.

* Updated `.devcontainer/devcontainer.json` to use the latest Go 1.25.3
version for consistency.

**Licensing and Miscellaneous**

* Added `apps/docs/` to the list of licensed directories in
`LICENSING.md`.

These changes ensure the documentation is now maintained in a modern,
scalable system and all project tooling is updated to support the new
structure.

title: Metrics
description: Overview of ZITADEL metrics, exposure endpoint, and compatibility with monitoring systems.
---
# Metrics
ZITADEL exposes operational and performance metrics to support monitoring, alerting, and capacity planning.
Metrics are **enabled by default** in standard deployments and are exposed via an HTTP endpoint that can be consumed by Prometheus and other monitoring systems that understand the Prometheus exposition format or use an OpenTelemetry pipeline.
## Metrics endpoint
ZITADEL exposes metrics at the following endpoint:
`/debug/metrics`
This endpoint returns a snapshot of the current metrics in **Prometheus-compatible exposition format**.
If you changed ports, paths, or network exposure as part of your deployment (for example via Helm values, reverse proxies, or ingress), adjust the endpoint accordingly.
## Instrumentation model
Internally, ZITADEL instruments metrics using **OpenTelemetry (OTel)**.
The exposed metrics include:
- **Process and runtime metrics**
(for example Go runtime, memory usage, goroutines)
- **HTTP and gRPC server metrics**
(request counts, latencies, error rates)
- **ZITADEL-specific metrics**
(server behavior and internal components available in your version)
The exact set of metrics and labels may evolve between ZITADEL releases.
## Collection and compatibility
The `/debug/metrics` endpoint can be consumed in multiple ways:
- **Prometheus** can scrape the endpoint directly.
- **OpenTelemetry Collector** can scrape the endpoint using a Prometheus receiver and forward metrics to other backends.
- **Managed monitoring platforms** (for example Grafana Cloud, Amazon Managed Service for Prometheus, Datadog, New Relic) can ingest the same endpoint via Prometheus-compatible agents or collectors.
ZITADEL does **not** require a specific metrics backend. Any system capable of scraping or ingesting Prometheus-format metrics can be used.
## Configuration
Metrics are enabled by default in standard ZITADEL deployments.
If metrics were explicitly disabled in your configuration, re-enable them before proceeding. The default configuration is defined in the project's `defaults.yaml` file:
- https://github.com/zitadel/zitadel/blob/main/cmd/defaults.yaml
Refer to the configuration documentation for details on enabling or adjusting metrics behavior.
## Next steps
Choose how you want to collect and store metrics:
- **Prometheus** — scrape metrics directly from ZITADEL
- **OpenTelemetry Collector** — aggregate and forward metrics to another backend
- **Managed observability platforms** — use their Prometheus-compatible agents
The following sections describe concrete setups, starting with **Prometheus**.
