Hi teams, I faced a issue about

status.hostIP

to use with metric reporters. • run as flink operator on eks • setup the k8s environment variables

- name: HOST_IP
    valueFrom:
      fieldRef:
        fieldPath: status.hostIP

• write it in

FlinkDeployment's spec.flinkConfiguration

flinkConfiguration     
    metrics.reporters: stsd
    metrics.reporter.stsd.factory.class: org.apache.flink.metrics.statsd.StatsDReporterFactory
    metrics.reporter.stsd.host: $HOST_IP
    metrics.reporter.stsd.port: '8125'
    metrics.reporter.stsd.interval: '60 SECONDS'

When actually executed, it is written as

metrics.reporter.stsd.host: $HOST_IP

under

flink-conf.yaml

and does not work properly. Do you give me advices for me?

Please advise what “Does not work properly” means? Do you see error messages? Are you missing data you expect to see? What version of Flink are you on?

@D. Draco O'Brien I apologize for the lack of information. The flink version I am using is 1.17, and the expected behavior is to inject the metrics.reporter.stsd.host information as an environment variable under flink-conf.yaml.

Like this;
metrics.reporter.stsd.host: ${HOST_IP}

However, this does not actually work, and the error log that occurs is as follows:

WARN  org.apache.flink.runtime.metrics.MetricRegistryImpl          [] - Error while reporting metrics
java.lang.IllegalArgumentException: unresolved address
