Network port requirements

Lists the network port numbers and their respective protocols used by Cloudera Observability On-Premises and dependent services.

Protocols are defined as follows:
  • UI Port (ui.port ), which serves the Cloudera Observability On-Premises user interface (UI) and communicates using HTTPS when TLS/SSL is enabled, otherwise it communicates using HTTP.
  • API Port (api.port), which listens for REST calls to API-based servers. It communicates using HTTPS when TLS/SSL is enabled, otherwise it communications using HTTP.
  • Metrics Port (webservice.port), which exposes an interface to the metrics that the Cloudera Observability On-Premises roles collect.
  • GRPC Port (grpc.port), which listens for gRPC requests against the backend servers. This protocol is used for inter-role communication.
