Say I have multiple namespaces on a kube cluster and each namespace has a RMQ container, and these RMQ containers are spread throughout a few nodes, is there a way to deploy one metricbeat pod (preferably as a daemonset) per node to monitor these RMQ containers? What's the best practice regarding using Metricbeat for monitoring, do you need one metricbeat per container? Thanks.
Metricbeat is installed as a daemonset to ensure that it can get all the node stats across all namespaces. So, you just need one instance of Metricbeat on every node in your k8s cluster
