[jira] [Updated] (FLINK-7122) When metric name contains special
characters then Graphite will not display them
[ https://issues.apache.org/jira/browse/FLINK-7122?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
wyp updated FLINK-7122:
-----------------------
Description:
When metric name contains special characters then Graphite will not display them, because Graphite(GraphiteUDP) only replace white space to {{-}}(See:[GraphiteUDP.java|https://github.com/dropwizard/metrics/blob/3.1-maintenance/metrics-graphite/src/main/java/com/codahale/metrics/graphite/GraphiteUDP.java#L109]). But Flink metric variable's associated value like this:
{code}
<job_id> -> 9e81f84c50820c304b8af2b16fa8140b
<task_id> -> cbc357ccb763df2852fee8c4fc7d55f2
<task_attempt_id> -> 690a6cebdd1bfa9edacfed50aa1d4807
<host> -> localhost
<operator_name> -> Sink: es
<task_name> -> Source: Custom Source -> TestFlat -> Map -> Sink: es
<task_attempt_num> -> 0
<job_name> -> MyFlinkJobs
<tm_id> -> 34d31d54c0031328a6ec8910e571a7f8
<subtask_index> -> 0
{code}
then {{metrics.scope.task}} 's full name will be
{{flinkjobs.localhost.taskmanager.34d31d54c0031328a6ec8910e571a7f8.MyFlinkJobs.Source: Custom Source -> TestFlat -> Map -> Sink: es.0}}, but this will not be display in Graphite, because Graphite didn't support {{:}},{{>}} etc. special characters.
