[JMX exporter] At most one of hostPort and jmxUrl must be provided

[Anurag Vaidya]

Hello everyone,

I am trying to use the JMX exporter to measure Kafka metrics. I have run the command "mvn package" and successfully build the package. I created the config.yaml file:

---

startDelaySeconds: 0

hostPort: 127.0.0.1:8080

username: 

password: 

jmxUrl: service:jmx:rmi:///jndi/rmi://127.0.0.1:8080/jmxrmi

ssl: false

lowercaseOutputName: false

lowercaseOutputLabelNames: false

whitelistObjectNames: ["org.apache.cassandra.metrics:*"]

blacklistObjectNames: ["org.apache.cassandra.metrics:type=ColumnFamily,*"]

rules:

  - pattern: 'org.apache.cassandra.metrics<type=(\w+), name=(\w+)><>Value: (\d+)'

    name: cassandra_$1_$2

    value: $3

    valueFactor: 0.001

    labels: {}

    help: "Cassandra metric $1 $2"

    type: GAUGE

    attrNameSnakeCase: false

However, when I try to see the metrics, I get the following error: At most one of hostPort and jmxUrl must be provided. I tried to remove the jmxUrl, but got the same error. Any advice?

That config is for explaining the configuration and should never be used directly. Use the kafka config at https://github.com/prometheus/jmx_exporter/tree/master/example_configs
