StreamNative Private Cloud telemetry supports Pulsar cluster usage data collection and the data will be stored using the Avro schema. The telemetry has modes: local and remote:
  • Local mode will store the Private Cloud cluster usage data in the local Pulsar’s topic and supports exporting usage data into CSV format.
  • Remote mode is a more automated solution since the Private Cloud cluster will send the telemetry data into StreamNative Cloud without user engagement.

​
Telemetry data

The usage data for the Pulsar cluster includes the CPU and memory usage for the PulsarBroker, BookkeeperCluster, PulsarProxy, ZookeeperCluster, Sink, Source, and Function components.

​
Telemetry local mode

Private Cloud users can access to the Pulsar cluster usage data through the cli tool snctl which support to display the cluster usage data in terminal or export the usage data in CSV format.

​
Prerequisites

  • Install the latest snctl v0.19.1 or above. Install snctl
  • Upgrade to the sn-operator helm chart v0.1.6 or above.
  • Enable the PulsarCoordinator object for your Pulsar cluster.

​
View the usage data

  • Get the Private Cloud Proxy external service endpoint:
kubectl get services -o jsonpath='{.items[?(@.spec.type=="LoadBalancer")].status.loadBalancer.ingress[0].ip}' -n pulsar

4.153.37.80
  • View the usage data through the usage-data get local commands:
snctl usage-data get local -u pulsar://4.153.37.80:6650

​
Export the usage data

  • Export the usage data through the extra -o, --csv-file-path flag with CSV format:
snctl usage-data get local -u pulsar://4.153.37.80:6650 -o usage-data.csv

​
Telemetry remote mode

StreamNative Operator has an inside agent sn-agent which works for usage data collection and telemetry sending. Under the remote mode, sn-agent will collect the usage data for Private Cloud clusters and send these usage data to the StreamNative Cloud, StreamNative will process these received usage data. Remote telemetry

​
Prerequisites

Remote mode has two prerequisites to enable:
  • Open the outbound network access: sn-agent will require the Internet connection to access to the SN Cloud public endpoint access:
    AddressDescriptions
    https://apps.sncloud.snio.cloudBroker data for TLS
    pulsar+ssl://apps.sncloud.snio.cloud:6651HTTPS request
  • License token with telemetry: remote mode needs specific license to enable, StreamNative will provide a new license to users and users can follow the Update license how to update the license.
