OpenShift 4: Traffic breakdown by Process ID, age and address on a CoreOS node
Issue
- We see a large number of connections are open when we review
netstatoutput on OpenShift Nodes, how can we determine which process or pod is managing those connections? - I see a lot of connections that I think are old and should be automatically closing but aren't - how can I see what they belong to?
- How to trace traffic by pod on nodes on OpenShift 4?
Environment
- Red Hat OpenShift Container Platform (RHOCP) 4.x
