Inspecting nodes

pprof is an extension of gperftools, a high-performance multi-threaded malloc implementation

Prerequisites

  • Add OPENSHIFT_PROFILE=web to /etc/sysconfig/atomic-openshift-node, openshift-master or origin-master
  • Restart OpenShift

In the event of a hung pod

Before deleting the pod or killing any processes, ssh into the affected node and run:

curl -o output.txt http://localhost:6060/debug/pprof/goroutine?debug=2

With output.txt being the destination file.
