> There are 2 annoying issues that was brought up by [~srimanth.gunturi] while
> working on FALCON-164. The use case is to get the status for a given entity
> for the past 1 or 2 or 3 or 7 days.
> 1. Instance status with out an end date fetches for a very small window
> Instance status take end date as optional but assumes one second from the
> start date which is too small a window.
> {code}
> private Date getEndDate(Date start, String endStr) throws FalconException
> {
> Date end;
> if (StringUtils.isEmpty(endStr)) {
> end = new Date(start.getTime() + 1000); // next sec
> } else {
> end = EntityUtil.parseDateUTC(endStr);
> }
> return end;
> }
> {code}
> May be assuming the current time might be appropriate instead.
> 2. The start date has to be on or after the start of the entity.
> If the user has created the entity 2 days back but specified the start date
> for looking at the instances in the past 7 days, it should fetch what is
> valid rather than complain that the start date is before the entity's start.
> This is quite unwieldy to work with in a dashboard use case. I'm not sure
> what the performance impact is for this API to be changed.
> Thoughts?
