Telemetry including host in the metric name

[scalp42]

Hi folks,

I noticed that some of the metrics include the consul host:

consul.consul-i-8de39448.runtime.total_gc_pause_ns
consul.consul-i-8de39448.runtime.num_goroutines

vs

consul.consul.catalog.deregister
consul.consul.fsm.kvs.lock

Is there a way to not have Consul include the host in the metric (which makes it act as a different metric, later instead of former) ?

This way we dont have to rely on extracting the source host from the metricic using regexes.

Hi @scalp42 it doesn't look like that's exposed via any Consul configuration right now. Unless that gets added, you'd have to make a mod here and build Consul:

That's a bummer, the source should not be in the metric name (only a few of them have the metric name in it).

It's an artifact of how the telemetry library works. It would probably be trivial to port the fix for this from vault

hashicorp/vault#419

Having the hostname in the metric kill us and it ends up duplicating a shit ton of metrics (vs datadog where you would pay per host for example).

@slackpad any chance we can see @nbrownus ported to consul as well?
