Edward Zhang commented on EAGLE-369:
------------------------------------
I would suggest to let user to edit template as they like, but Eagle provides
some predefined template. Because for those customized text information, we
have to custom template.
> Improve eagle alert email template to provide more useful information and
> user experience

> Key: EAGLE-369
> URL: https://issues.apache.org/jira/browse/EAGLE-369
> Project: Eagle
> Issue Type: Improvement
> Affects Versions: v0.3.1
> Reporter: Su Ralph
> Assignee: Su Ralph
> Fix For: v0.5.0
>
>
> From feedback:
> (1) Time Stamp needs to be human readable.
> (2) Consider capitalize wordings.
> (3) What does lowNum and highNum mean here? Do they mean number of live
> data nodes? How does this alert come out? Does that mean the current number
> of live data nodes go above the highNum or below the lowNum? The lowNum
> should display as “2,884” instead of “2884.0”.
> (4) The Description field should always be there. If description is not
> available, it should display as “Not provided by Policy Owner”.
> (5) Should we consider displaying the name of the policy owner? That way,
> people know whom to contact if they have question about the policy.
> (6) The information in the Actions Required field is too generic and it is
> not actionable. Can we do something about it?
> (7) The text alignment (now always align center) may consider to align
> left. Use want to make it look more professional.
> (8) Text font is not consistent across the message. Should align to one
> single font. Consider use Calibri as this is now the eBay official font
> type.
> (9) Lack of policy definition
> The definition is
> from every (e1 = hadoopJmxMetricEventStream[metric ==
> \"hadoop.namenode.fsnamesystemstate.numlivedatanodes\" ]) -> e2 =
> hadoopJmxMetricEventStream[metric == e1.metric and host == e1.host and
> (convert(e1.value, \"long\") - 2) >= convert(value, \"long\") ] within 5 min
> select e1.metric, e1.host, e1.value as highNum, e1.timestamp as start,
> e2.value as lowNum, e2.timestamp as end insert into tmp;
