----------------------------------------
Summary: Prometheus metric family type definitions are duplicated
Key: MINIFICPP-2488
URL: https://issues.apache.org/jira/browse/MINIFICPP-2488
Project: Apache NiFi MiNiFi C++
Issue Type: Bug
Reporter: Gábor Gyimesi
Assignee: Gábor Gyimesi
Currently all metric response nodes are mapped to a corresponding Prometheus
metric collection and every metric defines a separate metric family. Due to
this when metric names are duplicated and only different in labels, they define
separate Prometheus TYPE objects with the same name which causes duplicate type
definitions. This duplicate type definition causes errors in metric collectors
like Telegraf.
We should collect all minifi metrics in a single collection and group metrics
in families by metric name to avoid this issue.
