Introspect server status

The /info resource gives you information about the status of a ksqlDB Server, which can be useful for health checks and troubleshooting. You can use the curl command to query the /info endpoint:

1
curl --http1.1 -sX GET "http://localhost:8088/info" | jq '.'

Your output should resemble:

  "KsqlServerInfo": {
    "version": "0.29.0",
    "kafkaClusterId": "j3tOi6E_RtO_TMH3gBmK7A",
    "ksqlServiceId": "default_"
  }
}

You can also check the health of your ksqlDB server by using the /healthcheck resource:

1
curl --http1.1 -sX GET "http://localhost:8088/healthcheck" | jq '.'

Your output should resemble:
