  A GraphQL observability app for <a href="https://nautobot.com/">Nautobot</a> — Prometheus metrics and structured query logging.
</p>

## Overview

A Nautobot app that provides comprehensive observability for the GraphQL API. It includes two [Graphene middlewares](https://docs.graphene-python.org/en/latest/execution/middleware/) that collect Prometheus metrics and emit structured query logs — without modifying Nautobot's core code.

### Features

**Prometheus Metrics** (`PrometheusMiddleware`):

- **Request metrics**: Count and measure the duration of all GraphQL queries and mutations.
- **Error tracking**: Count errors by operation and exception type.
- **Query depth & complexity**: Histogram metrics for query nesting depth and total field count.
- **Per-user tracking**: Count requests per authenticated user for auditing and capacity planning.
- **Per-field resolution**: Optionally measure individual field resolver durations for debugging.
- All metrics appear at Nautobot's default `/metrics/` endpoint — no extra endpoint needed.

**Query Logging** (`GraphQLQueryLoggingMiddleware`):

- **Structured log entries**: Operation type, name, user, duration, and status for every query.
- **Optional query body and variables**: Include the full query text and variables in log entries.
- **Standard Python logging**: Route logs to any backend (file, syslog, ELK, etc.) via Django's `LOGGING` configuration.

**General**:

- **Zero configuration**: Automatically patches Nautobot's `GraphQLDRFAPIView` to load the middlewares — no manual `GRAPHENE["MIDDLEWARE"]` setup needed.

### Quick Install

```shell
pip install nautobot-app-graphql-observability
```

```python
# nautobot_config.py
PLUGINS = ["nautobot_app_graphql_observability"]
```
