I config the otel-collector-config.yaml followed by https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/0bd3c27f442a011ab853986d87f2b8fec040a4a4/receiver/jmxreceiver/README.md#Configuration

receivers:
  jmx:
    jar_path: /usr/local/opentelemetry-jmx-metrics.jar
    endpoint: 192.168.x.x:1616
    target_system: jvm
    collection_interval: 10s
    username: admin
    password: xxx
    resource_attributes:
      host_name: jmx-activemq

Start up failed with error

Error: cannot start pipelines: failed to parse Endpoint "192.168.x.x:1616": parse "192.168.2.60:1616": first path segment in URL cannot contain colon
2024/03/05 03:16:33 collector server run finished with error: cannot start pipelines: failed to parse Endpoint "192.168.x.x:1616": parse "192.168.x.x:1616": first path segment in URL cannot contain colon

Fixed by add // at the front of host:port, that works.

receivers:
  jmx:
    jar_path: /usr/local/opentelemetry-jmx-metrics.jar
    endpoint: //192.168.x.x:1616
    target_system: jvm
    collection_interval: 10s
    username: admin
    password: activemq
    resource_attributes:
      host_name: jmx-activemq

Is that a code bug or a doc enhancement?

You should really be asking these questions from the collector folks in https://github.com/open-telemetry/opentelemetry-collector-contrib/. As far as I know they reject the metrics jar when the has doesn't match what they expect.

Can I apply a Slack account in OpenTelemetry? I have already have the account and join ASF, but not permitted in OpenTelemetry part.

OpenTelemetry channels are in CNCF slack, anybody can join.

I made a mistake to check the support jars https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/receiver/jmxreceiver/supported_jars.go.
I just check the main -> v0.96.0, not match my test with 0.95.0.
So 1.32.0 matched 0.95.0, that works.
