[jboss-jira] [JBoss JIRA] (WFLY-13680) Generated metrics have duplicate labels

Jeff Mesnil commented on WFLY-13680:
------------------------------------
Which version of WildFly are you using?
In the latest build, the HELP line for the base_gc_total metric is printed only once as
expected:
{code}
# HELP base_gc_total Displays the total number of collections that have occurred. This
attribute lists -1 if the collection count is undefined for this collector.
# TYPE base_gc_total counter
base_gc_total{name="PS MarkSweep1"} 1.0
base_gc_total{name="PS Scavenge1"} 14.0
{code}
Generated metrics have duplicate labels

Key: WFLY-13680
URL: https://issues.redhat.com/browse/WFLY-13680
Project: WildFly
Issue Type: Bug
Components: MP Metrics
Reporter: Ivona Skorjanc
Assignee: Jeff Mesnil
Priority: Major
Attachments: kc_metric.txt
We are using Keycloak which generates metrics using the jBoss CLI:
[https://github.com/keycloak/keycloak-containers/blob/master/server/tools/...]
We want to use Telegraf (with the Prometheus input plugin) to read the generated
metrics. However, we get the following error:
{{Error in plugin: error reading metrics for [http://localhost:9990/metrics]: reading
text format failed: text format parsing error in line 34: second HELP line for metric name
"base_gc_total"}}
The base_gc_total metric appears twice for some reason. See the full metrics output in
the attachment.
