Aliaksandr Valialkin	fa19daf3bd	docs/MetricsQL.md: improve text formatting for better readability	2024-02-22 14:00:47 +02:00
Aliaksandr Valialkin	f7c3dee1c3	app/vmselect/promql: add `count_values_over_time()` MetricsQL function See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5847	2024-02-22 13:39:29 +02:00
Aliaksandr Valialkin	149d83e596	docs/MetricsQL.md: properly document how MetricsQL selects the lookbehind window - rate(m) isn't equivalent to rate(m[1i]) when step is smaller than the interval between samples. - default_rollup(m) isn't equivalent to default_rollup(m[1i]) when step is smaller than the interval between samples. These changes have been made in v1.85.3 as a part of https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3483 . See the corresponding commit - `9fa3f1dc57` .

Aliaksandr Valialkin	bdb743c88d	app/vmselect/promql: add drop_empty_series() function for dropping empty series before performing additional calculations This can be useful in the following queries: drop_empty_series(temperature <= 30) default 40 This query drops temperature series with all the values bigger than 30 on the selected time range, while replacing gaps in the remaining series with 40. The query without drop_empty_series: (temperature <= 30) default 40 would leave all the temperature series with all the values bigger than 30 on the selected time range, and replace all their values with 40. This is not what could be epxected in some cases like here - https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5071	2023-10-16 20:44:56 +02:00

Aliaksandr Valialkin	1c0e065216	app/vmselect/promql: add support for `_` delimiters in numeric values For example, 1_234_567_890 is equivalent to 1234567890, while 1.234_567_890 is equivalent to 1.234567890	2023-08-30 14:33:41 +02:00

Aliaksandr Valialkin	8815080030	app/vmselect/promql: add the ability to copy all the labels from `one` side of group_left()/group_right() operation This is performed by specifying `` inside group_left()/group_right(). Also allow specifying prefix for the copied labels via `group_left(...) prefix "..."` and `group_right(...) prefix "..."` syntax. For example, the following query adds all the namespace-related labels to pod info, and prefixes all the copied label names with "ns_" prefix: kube_pod_info on(namespace) group_left(*) prefix "ns_" kube_namespace_labels This resolves the following StackOverflow questions: - https://stackoverflow.com/questions/76661818/how-to-add-namespace-labels-to-pod-labels-in-prometheus - https://stackoverflow.com/questions/76653997/how-can-i-make-a-new-copy-of-kube-namespace-labels-metric-with-a-different-name	2023-07-17 19:07:39 -07:00
Aliaksandr Valialkin	be31bdc88c	app/vmselect/promql: recommend to use `(a op b) keep_metric_names` instead of `a op b keep_metric_names` The `a op b keep_metric_names` is ambigouos to `a op (b keep_metric_names)` when `b` is a transform or rollup function. For example, `a + rate(b) keep_metric_names`. So it is better to use more clear syntax: `(a op b) keep_metric_names` Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3710	2023-07-16 23:46:34 -07:00

Aliaksandr Valialkin	4cb024d8a3	all: add support for `or` filters in series selectors This commit adds ability to select series matching distinct filters via a single series selector. For example, the following selector selects series with either {env="prod",job="a"} or {env="dev",job="b"} labels: {env="prod",job="a" or env="dev",job="b"} The `or` filter is supported in all the VictoriaMetrics tools now.

This change can be useful for situations where only one type of rollup calculation is needed. For example, `rollup_rate(requests_total[5m], "max")`.
