how to trace the blueprint , and how to find the reason that BP failed

[#1]

in some cases we get failed during blueprint installation on ( new ambari cluster )

the last line that we run in order to install the blueprint is:

      curl -H "X-Requested-By: ambari" -X POST -u "$USER"":""$PASSWORD" http://$host:8080/api/v1/clusters/HDP -d @hostmapping.json

in case of blueprint failed , we can just to look from the ambari cluster GUI and see the secrives that failed

but this isn't gives us the root cause why bluprint failed

please advice how to trace the bluprint installation and find out on which exactly blueprint failed ?

@Michael Bronson

We can take a look at the "/var/log/ambari-server/ambari-serverlog" file to see why it failed. ambari-server.log logs the cause of blueprint installation failure.
