Graph Monitor¶

GraphMonitor is a simple HTTP-based cache service that stores and retrieves GraphQL endpoint URLs and schemas. It acts as a registry for GraphQL information, allowing services to look up endpoints without direct knowledge of them.

Endpoints¶

Method	Path	Purpose	Auth
GET	`/health`	Health check	None
GET	`/{name}`	Retrieve stored graph URL	X-Api-Key
POST	`/{name}`	Store a graph URL	X-Api-Key
GET	`/schema`	Retrieve stored GraphQL schema	X-Api-Key
POST	`/schema`	Store GraphQL schema	X-Api-Key

Usage¶

Store a Graph URL¶

curl -X POST http://localhost:5145/my-api \
  -H "X-Api-Key: your-key" \
  -H "Content-Type: text/plain" \
  -d "http://api.example.com/graphql"

Retrieve a Graph URL¶

curl http://localhost:5145/my-api \
  -H "X-Api-Key: your-key"

Health Check¶

curl http://localhost:5145/health

Running¶

Local Development¶

cd dotnet/GraphMonitor
$env:REDIS_URL="localhost:6379"
$env:MONITOR_API_KEY="dev-key"
dotnet run

Default port: 5145

Docker¶

docker build -f dotnet/GraphMonitor.Dockerfile -t graph-monitor .
docker run -e REDIS_URL=redis:6379 -e MONITOR_API_KEY=secret -p 5145:5145 graph-monitor

Configuration¶

Required environment variables:

REDIS_URL=localhost:6379
MONITOR_API_KEY=your-secret-key
