-----------------------------------
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.
