How to get started on Metrics API #4903
-
|
I am having hard time on finding relevant documentation on metrics api. The image on home as well as wiki seems to infer that metrics is not part of GRPC. So, is it a rest api? How can I access metrics of containers from containerd? |

@yagnasrinath Metrics are part of the GRPC API of the task service: https://github.com/containerd/containerd/blob/master/api/services/tasks/v1/tasks.proto#L67 containerd also exposes these metrics to the prometheus endpoint (if one is configured) exposed by the containerd daemon. |

This is the first time for me to use gRPC. I'm also playing around with the Metrics service, but unfortunately without success. I want to share the command that I think is not far away to send a successful request: I'm getting the following error: I hope that somebody can answer what I am missing here. I also hope that the command can inspire some of you. |
