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.

> 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;
