OpenTelemetry gateway is enabled on a cluster

If the gateway is enabled on your cluster, you must add the proxy_url in Otelcol Gateway Metrics Exporter and Otelcol Gateway RTM Logs Exporter in Cloudera Manager.

Adding proxy_url in Otelcol RTM Logs Exporter and Otelcol Metrics Exporter

  1. Log in to Cloudera Manager > Hosts > Hosts Configuration
  2. Search for otelcol_gateway_external_logs_exporter and add the proxy_url configuration. For example, 
    exporter_timeout:
  timeout: '45s'
retry_on_failure:
  enabled: false
proxy_url: http://proxy-host:port
auth:
  authenticator: $CDPAUTH_LOGS_EXTENSION_NAME
  3. Search for otelcol_gateway_external_metrics_exporter and add the proxy_url configuration. For example, 
    prometheusremotewrite/gateway-<rr_connector_count>:
    endpoint: $HOST_PARAM(otelcol_remote_write_url)
    timeout: 30s
    retry_on_failure:
      enabled: true
      initial_interval: 10s
      max_interval: 40s
      max_elapsed_time: 300s
    target_info:
      enabled: false
    auth:
      authenticator: cdpauth/gateway
    proxy_url: http://proxy-host:port
