Summary: Metron Service Checks Use Wrong Hostname
Key: METRON-1348
URL: https://issues.apache.org/jira/browse/METRON-1348
Project: Metron
Issue Type: Bug
Reporter: Nick Allen
The Metron service check can often use the incorrect hostname when checking the
Alerts UI, Management UI, REST, and Elasticsearch services.
Ambari can run the service check on any node in the cluster, not just the node
the service is actually running on. The service check code currently uses the
hostname on which the service check is running. If the service is not actually
installed on that host, the service check will incorrectly fail.
The service check code should be updated to find the hostname where the service
is installed and use that hostname.
For example, here is a log of a service check that is looking on the wrong host
for the Metron REST service.
