Monitoring and Observability

WunderGraph exposes several metrics that allow you to get a better understanding of your application's performance. The following metrics are available:

• Served HTTP requests (tagged per operation and status code)
• Size of incoming HTTP requests
• Size of outgoing HTTP responses
• Duration of received HTTP requests
• Outgoing HTTP requests sent to upstream APIs (tagged per host and status code)
• Duration of outgoing HTTP requests (tagged per host and status code)

By default, Prometheus is enabled and serves its metrics on http://<host>:8881/metrics. To disable it or to use a custom port, use the prometheus field when calling configureWunderGraphApplication():

// wundergraph.config.ts

configureWunderGraphApplication({
    ...
    options: {
        prometheus: {
            enabled: true, // Set to false to disable
            port: 8881, // Defaults to 8881
        }
    },
    ...
});
