Monitoring

There are three API endpoints you can call to check the status of your instance: /healthz, healthz/readiness, and /metrics.

healthz and healthz/readiness

The /healthz endpoint returns a standard HTTP status code. 200 indicates the instance is reachable. It doesn't indicate DB status. It's available for both self-hosted and Cloud users.

Access the endpoint:

<your-instance-url>/healthz

The /healthz/readiness endpoint is similar to the /healthz endpoint, but it returns a HTTP status code of 200 if the DB is connected and migrated and therefore the instance is ready to accept traffic.

Access the endpoint:

<your-instance-url>/healthz/readiness

metrics

The /metrics endpoint provides more detailed information about the current status of the instance.

Access the endpoint:

<your-instance-url>/metrics

Enable metrics and healthz for self-hosted n8n

The /metrics and /healthz endpoints are disabled by default. To enable them, configure your n8n instance:

# metrics
N8N_METRICS=true
# healthz
QUEUE_HEALTH_CHECK_ACTIVE=true

Refer to Configuration methods for more information on how to configure your instance using environment variables.
