We have a number of gateway containers running on our linux server. Thought I could use the gateway dashboard to look at gateway health, but just getting 'Metric Not Found'. Is this normal or just an artifact of ignition running inside of a container?
Not normal, it should work just fine there.. Anything notable in the logs?
What about browser console/network logs?
At this point, we might also benefit from more details on your container configuration (is this on Docker Engine? perhaps a docker inspect <container name>, or Compose/K8s YAML as it applies), installed modules, etc. If sensitive, you can always submit a support ticket as well.
