It would be nice to be able to fetch a list of metrics around a particular point in time.
- fetch the current value being held in a metric. I may only want to know the last value written to a metric: Eg "what is the current page view for my site"
- fetch the value of a metric at a specific time point. Similar to the above example, but instead of the current value its set to something else. Eg "what was the page view for my site exactly 24 hours ago"
- fetch the X number of data points around this specific time point. This would be similar to the above but geared more toward gauge data and not counter data. Eg give me the 5 values closest to time Y so that I can calculate a quick average at that time point.
