Something is broken ...
lets say heat is not starting up ..
what do we do ?
calm down!
check logs ( /var/log/heat-api.log, /var/log/heat-api-cfn.log, /var/log/heat-engine.log)
Do you see any errors there ?? ( most of the times this should be sufficient)
but what if there is not error in the logs.. since the service is not even starting ?
try restarting the service(systemctl comes to rescue)
Just getting a failed status but no details ?try debugging
here are few links which will help
