I am using prometheus to gather metrics about releases. One good entry point for that is the /metrics endpoint exposed by Tiller. However, I am missing metrics for the RollbackRelease method, as it's not present in the output. I took a quick loot at the code from #2171 but I don't see why the metrics are not present.

@bacongobbler - I see that you did a first triage of this issue. Is there anything I can do to at least help confirm it? It might be that "I'm holding it wrong", one can never know :-)

[bacongobbler]

If you could provide your setup instructions that may be helpful :)

@bacongobbler - I did not set up my environment myself, but what I know is that:

• we have a k10s cluster
• we use helm for deployments
• we use prometheus for gathering metrics
• prometheus is successfully scraping metrics from tiller
• tiller does not have anny metrics for the RollbackRelease method

To access the metrics entry point I did the following

$ kubectl port-forward tiller-deploy-679c587747-cx4vg 44135
$curl -s http://localhost:44135/metrics | grep Rollback

If I try to access other metrics, e.g. for releases they appear just fine

$ curl -s http://localhost:44135/metrics | grep InstallRelease
grpc_server_handled_total{grpc_code="OK",grpc_method="InstallRelease",grpc_service="hapi.services.tiller.ReleaseService",grpc_type="unary"} 156
grpc_server_handled_total{grpc_code="Unknown",grpc_method="InstallRelease",grpc_service="hapi.services.tiller.ReleaseService",grpc_type="unary"} 61
grpc_server_msg_received_total{grpc_method="InstallRelease",grpc_service="hapi.services.tiller.ReleaseService",grpc_type="unary"} 217
grpc_server_msg_sent_total{grpc_method="InstallRelease",grpc_service="hapi.services.tiller.ReleaseService",grpc_type="unary"} 156
grpc_server_started_total{grpc_method="InstallRelease",grpc_service="hapi.services.tiller.ReleaseService",grpc_type="unary"} 217

@bacongobbler - does that at least point you in the right direction?

[bacongobbler]

Yes, thank you.
