Flink Metrics Naming

[Mason Chen]

Can anyone give insight as to why Flink allows 2 metrics with the same “name”?

For example,

getRuntimeContext.addGroup(“group”, “group1”).counter(“myMetricName”);

And

getRuntimeContext.addGroup(“other_group”, 
“other_group1”).counter(“myMetricName”);

Are totally valid.


It seems that it has lead to some not-so-great implementations—the prometheus 
reporter and attaching the labels to the metric name, making the name quite 
verbose.
