The default installation of prometheus comes with these three dashboards

• Prometheus-Operator UI
• AlertManager UI
• Grafana UI

Before Accessing the UI make sure you have all the prometheus necessary pods are up and running

Prometheus ports

These are the standard ports which will be helpful while dealing with Prometheus server and it’s associated service.

• 9090 - Prometheus server
• 9091 - Pushgateway
• 9092 - UNALLOCATED (to avoid collision with Kafka)
• 9093 - Alertmanager
• 9094 - Alertmanager clustering
