(I reckon this has probably already been requested, at least in other forms)
Feature Request - a new type of Template Variable:
- Either a Date/Time specification;
- Or a Date/Time Period specification.
If we have #1, the simplest, I can add 2 DateTime selectors to the templates row, say “$beginning1” and “$end1”, and then I should be able to make a graphic or whatever that uses those 2 time filters.
Then, I can build, for example:
# Row 1 - CPU chart, WHERE time >= $beginning1 and time <= $end1
# Row 2 - CPU chart, WHERE time >= $beginning2 and time <= $end2
Thus being able to compare time periods. Example, compare today vs yesterday, a very important requirement for analysis of trending over time or of comparison of specific periods (ex: this Black Friday, vs last Black Friday).
Of course, current Grafana’s structure won’t cope with that, since the graphics’ X-Axis are per Dashboard’s time specification instead of per time specification of its own.
