Aliaksandr Valialkin	7e6ec0bbe9	app/vmselect/promql: return back the behaviour for `deriv()` function when the lookbehind window doesnt contain enough points It is expected that the `deriv(m[d])` returns non-empty value if the lookbehind window `d` contains less than 2 samples in the same way as `rate()` does. This is a follow-up after `3e084be06b` .	2021-10-07 12:55:58 +03:00
Roman Khavronenko	0a8804d6aa	app/vmselect: make `predict_linear` and `deriv` compatible with Prometheus (#1681 ) Previously, `predict_linear` returned slightly different results comparing to Prometheus. The change makes linear regression algorithm compatible with Prometheus. `deriv` was excluded from the list of functions which can adjust the time window for the same reasons.	2021-10-07 12:55:56 +03:00

Roman Khavronenko	95ddfda894	app/vmselect: fix binary comparison func (#1667 ) The fix makes the binary comparison func to check for NaNs before executing the actual comparison.

Roman Khavronenko	6061464d80	app/vmselect: `quantile` func compatiblity with Prometheus (#1646 ) * app/vmselect: `quantile` func compatiblity with Prometheus The `quantile` func was previously calculated by https://github.com/valyala/histogram package. The result of such calculation was always the closest real value to requested quantile. While in Prometheus implementation interpolation is used. Such difference may result into discrepancy in output between Prometheus and VictoriaMetrics. This commit adds a Prometheus-like `quantile` function. It also used by other functions which depend on it, such as `quantiles`, `quantile_over_time`, `median` etc. https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1625 Signed-off-by: hagen1778 <roman@victoriametrics.com> * app/vmselect: `quantile` review fixes * quantile functions were split into multiple to provide different API for already sorted data; * float64sPool is used for reducing allocations.

Roman Khavronenko	d5ba8248cc	vmalert: expose new metrics for tracking number of produced samples during last evaluation (#1518 ) * vmalert: expose new metrics for tracking number of produced samples during last evaluation Two new metrics were added to track the number of samples produced during the last evaluation: * vmalert_recording_rules_last_evaluation_samples * vmalert_alerting_rules_last_evaluation_samples The gauge type is used to remain consistent with Prometheus metric `prometheus_rule_group_last_evaluation_samples` which is on the group level. However, the counter type was considered as well. Two metrics instead of one are used to make it easier to separate recording and alerting rules. It is likely, number of samples produced by recording rules is more important so people will refer to it more frequently. The expected usage of the new metric is the following: ``` - alert: RecordingRuleReturnsEmptyResults expr: sum(vmalert_recording_rules_last_evaluation_samples) by(recording) < 1 annotations: summary: Recording rule {{$labels.recording}} returns empty results.

But now user can specify whether to just log these errors (remoteRead.ignoreRestoreErrors=true) or to stop the process (remoteRead.ignoreRestoreErrors=false).

This is mostly needed to produce consistent time series with timestamps unaffected by vmalert start time. Now, timestamp becomes predictable. Additionally, adjustment is similar to what Grafana does for plotting range graphs. Hence, recording rule series and recording rule expression plotted in grafana suppose to become similar in most of cases.	2021-04-30 09:56:46 +03:00

To avoid such situations, vmalert now will use returned timestamp instead of `lastExecTime`.	2021-04-27 00:16:45 +03:00

This especially useful for `changelog` docs. Table of contents for `vmctl` is dropped, since we already have it autogenerated on .github.io. No link changes expected.

Roman Khavronenko	304512b668	vmalert-989: return non-empty result in template func `query` stub to pass validation (#1002 ) On templates validation stage vmalert does not acutally send queries, so for complex chained expression validation may fail.
