For managed environments (cloud and managed on-premise), Grafana, Prometheus, and several exporters aggregate system metrics, render dashboards, and send alerts. Application logs are collected in OpenObserve inside the same environment. If you run unmanaged on-premise, you are responsible for metrics, logging, and alerting. Paragon does not have access to those tools unless you grant it. Monitored systems include:
  • Load balancer
  • Redis
  • Postgres
  • Postgres worker queue
  • Redis worker queue
  • Workflow executions
  • Connect Proxy Requests
  • Microservices

​
