-------------------------------------
Summary: Typo mistake in "Metric Report page" of the documentation
Key: FLINK-25830
URL: https://issues.apache.org/jira/browse/FLINK-25830
Project: Flink
Issue Type: Improvement
Components: Documentation
Reporter: ChengKai Yang
Hi, I think I find a typo mistake in the documentation:
[This page:"Report
page"|https://nightlies.apache.org/flink/flink-docs-release-1.14/docs/deployment/metric_reporters/#reporter]
.
In the YAML part:
{code:java}
```yaml
metrics.reporters: my_jmx_reporter,my_other_reporter
metrics.reporter.my_jmx_reporter.factory.class:
org.apache.flink.metrics.jmx.JMXReporterFactory
metrics.reporter.my_jmx_reporter.port: 9020-9040
metrics.reporter.my_jmx_reporter.scope.variables.excludes:job_id;task_attempt_num
metrics.reporter.my_jmx_reporter.scope.variables.additional:
cluster_name:my_test_cluster,tag_name:tag_value
metrics.reporter.my_other_reporter.class:
org.apache.flink.metrics.graphite.GraphiteReporter
metrics.reporter.my_other_reporter.host: 192.168.1.1
metrics.reporter.my_other_reporter.port: 10000
```
{code}
This property:
metrics.reporter.my_jmx_reporter.scope.variables.excludes:job_id;task_attempt_num
If the user copies this property to the conf/flink-conf.yaml, the user will get
a warning in the log like this:
{code:java}
// code placeholder
2022-01-26 22:45:31,642 WARN
org.apache.flink.configuration.GlobalConfiguration [] - Error while
trying to split key and value in configuration file
/opt/module/flink-1.14.2/conf/flink-conf.yaml:277:
"metrics.reporter.my_jmx_reporter.scope.variables.excludes:job_id;task_attempt_num"
{code}
So there should have a space between
"metrics.reporter.my_jmx_reporter.scope.variables.excludes:" and
"job_id;task_attempt_num".
