Heat cfn-push-stats failed with '403 SignatureDoesNotMatch'

Solution Verified - Updated -

Issue

  • We’re trying to deploy a HA instance with Heat that will reprovision a guest on a shutdown, by using this template as a reference.
  • Our template works perfectly with Fedora20-x86_64-cfntools, but when we’re using a Rhel65 image with heat-cfntools rpm installed the instance is keep being restarted. ( The WatchCloud alarm state is always on “ALARM”.)
  • I tried to debug the cfn-tools scripts and found out that there is a problem with cfn-push-stats.
