Application Metrics

EventNative supports Prometheus as a metrics destination. It uses the official Go client library. Metrics are available under /prometheus?token=$admin_token endpoint with admin token authorization. In addition, this library collects system metrics. It's suitable to use the official Grafana dashboard template for monitoring them. 
Configuration
By default metrics collection is disabled. For enabling it put the following keys in EventNative YAML configuration:
server:
  admin_token: your_admin_token
  metrics:
    prometheus.enabled: true
    
destinations:
...
