Shannon Carey updated FLINK-5425:
---------------------------------
Description:
In metrics at the jobmanager level and below, the "<host>" scope variable is
being replaced by the IP rather than the hostname. The taskmanager metrics,
meanwhile, use the host name.
You can see the job manager behavior at
https://github.com/apache/flink/blob/a1934255421b97eefd579183e9c7199c43ad1a2c/flink-runtime/src/main/java/org/apache/flink/runtime/jobmaster/JobManagerRunner.java#L147
compared to TaskManagerLocation#getHostname().
The problem with this is mainly that due to the presence of "." (period)
characters in the IP address and thereby the metric name, the metric names show
up strangely in Graphite/Grafana, where "." is the metric group separator.
If it's not possible to make jobmanager metrics use the hostname, I suggest
replacing "." with "-" in the <host> section.
