When you mouse over a heat chart icon at the moment, you get text such as:

"severity": Rule Name

When in a group focus with the group collapsed, it would be nice to see the number of servers affected by the current severity level shown in the mouse over text as well. 

How to repeat:

Suggested fix:
Add text that shows the number of servers affected by the current severity shown in the mouse over text.

See heatChartFragment.jsp for how the tooltip is built and it accesses HeatChartObject.java to get the severity and rule name.   Looks like we'll need to tweak heatChartFragment.jsp to add a (# servers with alarm) to the tooltip if the number is greater than zero and pass in that number to HeatChartObject.java.

Take a look at heatChartObject.jsp and HeatChartObject.java for the places to add this information.

  EM-2847: compute how many servers have an alarm at the same level as the worst in the group, per-Rule.  Add such a count to the tooltip on the heat chart dot.

I should note that I did try the heatchart with small-font-size numbers centered inside the dots; consensus was that it was pretty much unreadable, and made the dots cluttered.

I thought about getting rid of the dots, and just setting the background color of the heat chart cell to the dot's color; this would let us use normal-size numbers (and double/triple digits) instead of a smaller font that could be inside the dot's circle.  Ultimately I decided against this for a few reasons.  First, there's at least one dot that is (just a bit) more than a single color (the "unknown" dot, with an 'X' through it).  Second, getting rid of using an icon/image would prevent us from using some other shape (such as a check, exclamation point or stop sign) to serve as a differentiator for color-blind users.   We don't have time to do that for 2.2, but it'd be weird to change things now, then maybe change them again later.

So, here, only the tooltips are changed. :(

I've added a note to the 2.2.0 changelog, and updated the corresponding area of the docs.
