Subject [jira] [Commented] (AMBARI-7284) Hadoop cluster alerts have not been updated for Hadoop 2.4 and 2.5
Date Fri, 12 Sep 2014 18:39:33 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-7284?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14131898#comment-14131898
] 

Matt Foley commented on AMBARI-7284:
------------------------------------

This is probably an issue with sys_logger.py.  See the previous-generation issue AMBARI-4435,
which provided this functionality for Ambari 1.5.0 and Hadoop-1.x.

>             Project: Ambari
>          Issue Type: Bug
>    Affects Versions: 1.6.0
>         Environment: Hadoop branch-2, release 2.4 or 2.5.
>            Reporter: Nicholas Yao

> Many /var/log/message alerts we keyed off of previously are no longer working or valid.
It appears that many hadoop 1.x terms such as jobtracker, tasktracker and templeton still
exist, when Ambari is being used with hadoop 2.x.
> I believe existing rules need to be modified for the following service name changes:
> resourcemanager_process_down
> resourcemanager_process_down_ok
> resourcemanager_rpc_latency
> resourcemanager_rpc_latency_ok
> resourcemanager_cpu_utilization
> resourcemanager_cpu_utilization_ok
> nodemanagers_down
> nodemanagers_down_ok
> nodemanager_process_down
> nodemanager_process_down_ok
> webhcat_down
> webhcat_down_ok
> It also appears that existing messages are getting improperly matched as we see the following
HADOOP_UNKNOWN_MSG in /var/log/messages:
> Jul 15 10:36:34 pitH1 nagios[35331]: Warning: Hadoop: HADOOP_UNKNOWN_MSG# Event Host=pitH1.td.teradata.com
Service Description=HDFS::Percent DataNodes with space available(WARNING), WARNING: total:6,
