> 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.
