Add custom label(s) to JVM metrics

[dmbrazhnikov]

Hi! Could you please explain is there any way to add custom label(s) to native JVM metrics (jvm_*)? Maybe override via listener configuration or something like that. It could be quite useful because I want my Jmeter to write it's metrics in the same VictoriaMetrics tenant as some other Java apps do, so it'll be good to separate metrics from different sources to avoid mish-mash.

As of right now, I don't believe you can. Those metrics are coming from the prometheus java library itself. We (this library) can instantiate the objects, but I'm not 100% sure from reading these docs that it's possible to override their metric names.
