Why Prometheus is monitoring wrong OpenShift Node IPs ?

Solution Verified - Updated -

Issue

When using Prometheus to monitor OpenShift Nodes, when the nodes are configured to use openshift_cloudprovider_kind=openstack , it tries to monitor non-OpenShift IPs and reports connection problems.

Environment

  • OpenShift Container Platform 3.4
  • Prometheus as monitoring platform
  • Node with more than 1 IP, and some IPs not reachable from Prometheus
