Prepares data from Products.ZenEvents.EventManagerBase.getEventSummary
for rendering in the eventrainbow template macro.
Each cell of the old-style event rainbow needs a CSS class specified
in order to render its color, fill and border style. evtprep determines
the proper class and returns it, along with a string representation of
the number of live and acknowledged events.
>>> from Products.ZenEvents.EventManagerBase import evtprep
>>> evtprep(['zenevents_5_noack noack', 2, 2])
{'cssclass': 'zenevents_5_noack noack empty thin', 'data': '2/2'}
>>> evtprep(['zenevents_5_noack noack', 1, 2])
{'cssclass': 'zenevents_5_noack noack', 'data': '1/2'}
- Parameters:
evts (tuple) - A tuple of the form (Severity string, Number Acknowledged int,
Number Live int) - Returns:
- A dictionary of the form {'cssclass': Class string, 'data':
Event count representation string}
