As an AF Administrator, I want to configure an Analysis Template for Event Frames with a True For parameter that would have it's value stored in an AF Attribute (configuration item). The use case is that elements built from the template will have Event Frames that will require a different True For value. I would like to have the analysis both base off a template and with the possibility of having different True For values. It would also be nice to have a True For parameter for the End Time. This is already a request:

When building templates specifically for monitoring a "problem" condition, not all the elements will behave the same way, Given each element's unique behavior, some may need a longer time before triggering the event and others will need less time trigger. Being able override the time specified in the template or better still, reference an attribute for the configuration would make this far more flexible.
The ability to set the True For in a Variable would allow for the customer to configure this based off there machines. Creating a event frame generation for downtime, we tried to implement a TimeGT function with a threshold variable that held the Start Trigger up until it had been at least the configured amount of time. With the Event Frame Generation being a event triggered analysis, this would not always correctly trigger a event frame. If the analysis goes to periodic, the start time of the event frame is the period instead of the trigger time of the start trigger. If the True For was configurable in an attribute, that would allow for better variability from different elements.
