Brian Brazil c77c3a8c56 promql: Limit extrapolation of delta/rate/increase
The new implementation detects the start and end of a series by
looking at the average sample interval within the range. If the first
(last) sample in the range is more than 1.1*interval distant from the
beginning (end) of the range, it is considered the first (last) sample
of the series as a whole, and extrapolation is limited to half the
interval (rather than all the way to the beginning (end) of the
range). In addition, if the extrapolated starting point of a counter
(where it is zero) is within the range, it is used as the starting
point of the series.

Fixes #581

Brian Brazil bac1f28cad Similar to topk/bottomk, have sort/sort_desc put NaN at end.
This makes topk and bottomk consistent with the sorting functions,
as per #1271.

Fabian Reinartz 33aab4169c Anchor regexes in vector matching
This commit makes the regex behavior of vector matching consistent with
configuration and label_replace() by anchoring it.

Brian Brazil 5740a8fade promql: Remove deprecated 2nd argument to delta()
This change is breaking, use increase() instead.

I'm not cleaning up the function in this PR, as my solution to #581 will
rewrite and simplify increase/rate/delta.

Brian Brazil 29e8dc2c49 promql: Add 'bool' modifier to comparison functions
When doing comparison operations on vectors, filtering
sometimes gets in the way and you have to go to a fair bit of
effort to workaround it in order to always return a result.
The 'bool' modifier instead of filtering returns 0/1 depending
on the result of the compairson.

This is also a prerequisite to removing plain scalar/scalar comparisons,
as it maintains the current behaviour under a new syntax.

Brian Brazil d6a80c2b76 promql: Add support for predict_linear(my_timeseries[1h], 7200)
This will give a prediction for the value of my_timeseries in 2 hours,
based on the last hour of data.

Fabian Reinartz 94cd321be1 promql: error if all label matchers are empty. 2015-06-22 15:33:44 +02:00
Julius Volz 5e2d1c1464 Deprecate `keeping_extra`, rename it to `keep_common`.
`keep_common` is more in line with the function name
`drop_common_labels()` terminology-wise, and also more in line with
`group_left`/`group_right` (no `...ing` verb suffix).

We could also go the full way and call it `keep_common_labels`. That
would have the benefit of being even more consistent with the function
`drop_common_labels()` and would be more explanatory, but it also seems
quite long.
