Pulsar Detector

The Pulsar detector monitors the health of Pulsar clusters. When you need to monitor the distribution latency from message sending to message consumption in one cluster or across clusters, you can use the Pulsar detector. The Pulsar detector enables you to easily integrate with existing monitoring tools like Prometheus, and check the critical metrics in Grafana.

Enable Detector

To enable the Audit Log on StreamNative Private Cloud, you need to configure them on the PulsarCoordinator CR:

spec:
  detector:
    serviceEndpoint:
      pulsarServiceURL: 'pulsar://brokers-broker-headless:6650'
      webServiceURL: 'http://brokers-broker-headless:8080'

Metrics

Pulsar detector supports the following metrics. You can check the complete list of metrics in Grafana.

Name	Type	Description
pulsar_detector_e2e_latency_ms	Summary	The distribution latency from message sending to message consumption.
pulsar_detector_publish_latency_ms	Summary	The distribution latency of message sending.
pulsar_detector_geo_latency_ms	Summary	The distribution latency from message sending to message consumption across clusters.
pulsar_sla_messaging_up	Gauge	Whether the message publishing service is running.
pulsar_sla_webservice_up	Gauge	Whether the webservice is running. The value `1` means the webservice is running. The value `0` means the webservice is not running.
