Subject [jira] [Created] (AMBARI-2920) Rename alert titles and descriptions
Date Thu, 15 Aug 2013 21:59:52 GMT
Yusaku Sako created AMBARI-2920:
-----------------------------------

             Summary: Rename alert titles and descriptions
                 Key: AMBARI-2920
                 URL: https://issues.apache.org/jira/browse/AMBARI-2920
             Project: Ambari
          Issue Type: Improvement
          Components: client
    Affects Versions: 1.4.0
            Reporter: Yusaku Sako
            Assignee: Yusaku Sako
             Fix For: 1.4.0


Currently Nagios alerts are shown in Ambari UI like so:
* (green check) NameNode process down <- means NameNode process is up
* (red X) NameNode process down <- means NameNode process is down
* (green check) Percent DataNode down <- means % of DataNodes that are up is above the
threshold
* (red X) Percent DataNode down <- means % of DataNodes that are up is below the threshold
* (green check) Nagios status log staleness <- means Nagios status log is fresh
* (red X) Nagios status log staleness <- means Nagios status log is stale

When a user sees the word "down" with a positive indication (green check) for it, it's confusing.
 It's like saying "this is red" in green... is it green or red?

The proposal here is to rename these alerts, like so:
* (green check) NameNode process <- means NameNode process is up/healthy
* (red X) NameNode process <- means NameNode process is down/unhealthy
* (green check) Percent DataNodes live <- means % of DataNodes that are up/healthy is above
the threshold
* (red X) Percent DataNodes live <- means % of DataNodes that are up/healthy is below the
threshold
* (green check) Nagios status log freshness <- means Nagios status log is fresh
* (red X) Nagios status log freshness <- means Nagios status log is stale

Also there are inconsistencies in the way we show component names in alert titles and descriptions
(like "templeton server status" to mean "WebHCat Server status", etc).  These need to be fixed.
