[jira] [Updated] (HDDS-7394) OM RPC FairCallQueue decay decision metrics list caller username in the metric
[ https://issues.apache.org/jira/browse/HDDS-7394?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Christos Bisias updated HDDS-7394:
----------------------------------
Summary: OM RPC FairCallQueue decay decision metrics list caller username in the metric (was: OM RPC FairCallQueue decay decision metrics list caller username in the metric instead of a label)
> OM RPC FairCallQueue decay decision metrics list caller username in the metric
> ------------------------------------------------------------------------------
>
> Key: HDDS-7394
> URL: https://issues.apache.org/jira/browse/HDDS-7394
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Christos Bisias
> Assignee: Christos Bisias
> Priority: Major
>
> On the Prometheus endpoint for the OM, in the DecayRpcScheduler summary for users, the username is exposed in the metric name, instead of in a label.
> In the below example, the username(hadoop) is between caller and metric type(volume or priority):
> {code:java}
> # TYPE org_apache_hadoop_ipc_decay_rpc_scheduler_call_volume counter
> org_apache_hadoop_ipc_decay_rpc_scheduler_call_volume{context="ipc.9862",hostname="1ad339cc5aba"} 21
> # TYPE org_apache_hadoop_ipc_decay_rpc_scheduler_caller_hadoop_volume counter
> org_apache_hadoop_ipc_decay_rpc_scheduler_caller_hadoop_volume{context="ipc.9862",hostname="1ad339cc5aba"} 21
> # TYPE org_apache_hadoop_ipc_decay_rpc_scheduler_decayed_call_volume counter
> org_apache_hadoop_ipc_decay_rpc_scheduler_decayed_call_volume{context="ipc.9862",hostname="1ad339cc5aba"} 21 {code}
> It makes almost impossible to monitor these values as every time a new user shows up we need to register a new metrics name.
> The OM jmx endpoint registers the metrics name as expected.
