> Prometheus metric family type definitions are duplicated

> Project: Apache NiFi MiNiFi C++
> Issue Type: Bug
> Reporter: Gábor Gyimesi
> Assignee: Gábor Gyimesi

>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> 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.
