Node exporter does not provide per container metrics, it looks at the whole node. This is sometimes difficult from inside a container, thus the warning.
For metrics about containers, check out cAdvisor: https://github.com/google/cadvisor In Prometheus it is common to have metrics broken out by labels. For example, the CPU metrics in node exporter are all per CPU core, and we expect you to aggregate them into whichever form you need. Can you share your query and what the output is, especially what labels it has? /MR On Fri, Nov 26, 2021, 18:50 Anne Schumann <[email protected]> wrote: > Hi there, > > I am new with Prometheus and I am facing issues with duplicate entries > visualised with grafana.
