---------------------------------------------
Summary: Logging improvement during the Upgrade when there is
invalid Alert definition
Key: AMBARI-22891
URL: https://issues.apache.org/jira/browse/AMBARI-22891
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.6.1
Reporter: amarnath reddy pappu
If there is invalid definition/json in alert definition then Upgrade would fail
with below exception. there is no way to determine which alert is causing the
issue here.
its not clear how this alert definition gets corrupted but we have seen this
with 3 to 4 customers already - printing the alert definition name would he
helpful in support point of view to determine the root cause.. other wise it is
very difficult to find it out - had a give a dev patch to customers to find it
out.

*no* further _formatting_ is done here{noformat}
