@Alexander Feldman It will be interesting to know what process you are trying to monitor. Normally the Alert definitions are tagged to a component name while you define. But might be there are options which I'm not aware of though. One of the example - https://github.com/monolive/ambari-custom-alerts ... View more

@chandramouli muthukumaran if you intend to use the /opt/Symantec/hadoop/hdfs/namenode for namenode and /opt/Symantec/hadoop/hdfs/data only then you can remove the other entries. Save and then you might need to restart the HDFS and corresponding services as indicated by ambari. Incase if you have multiple directories for Data then add those entries like this. /opt/Symantec/hadoop/hdfs/data1,/opt/Symantec/hadoop/hdfs/data2,/opt/Symantec/hadoop/hdfs/data3 Hope this helps. ...

Currently ambari alerts for kafka is just to monitor the kafka broker process on a particular port. Is there a way we can monitor and alert any other parameters like under replicated counts or active controller count etc... ? After upgrading to Ambari 2.2.2 we are able to create and add new widgets for these fields. But there is nothing in the alerts section. Has anyone been successful in setting up the custom alerting for these parameters? ... View more
