I am trying out collecting metrics and logs from pods in our staging Kubernetes cluster. I have followed the instructions here: [Run Metricbeat on Kubernetes | Metricbeat Reference [8.1] | Elastic](https://www.elastic.co/guide/en/beats/metricbeat/current/running-on-kubernetes.html)

The cluster has two nodes and 269 running pods. There is a metricbeat pod on each of the two nodes and each eats up about 250 MB of memory, which seems a bit too much to me. When running metricbeat on a server without containerization, the memory footprint is barely 50 MB.

Also, the default Kubernetes manifests provided by Elastic declare `resources.limits.memory: 200Mi` which made the pods OOMKilled until I raised that limit myself, so that suggests to me something is off.

Is such a high memory usage to be expected? If so, is there any ways to optimize? (E.g. only collect metrics from some pods - determined by labels, annotations etc).

Using version 7.16.3. Thanks!

I did not, still waiting for suggestions.
