Aliaksandr Valialkin	b2f9b9d634	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 20:59:21 +02:00

Aliaksandr Valialkin	5ace0701d3	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 16:58:30 -07:00
Aliaksandr Valialkin	cc54fa2a56	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 23:47:15 -07:00

Aliaksandr Valialkin	a7fdc3fcc7	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.

Roman Khavronenko	79eb33556e	metricsql: support optional 2nd argument for rollup functions (#3841 ) * metricsql: support optional 2nd argument for rollup functions Support optional 2nd argument `min`, `max` or `avg` for rollup functions: * rollup * rollup_delta * rollup_deriv * rollup_increase * rollup_rate * rollup_scrape_interval If second argument is passed, then rollup function will return only the selected aggregation type. This change can be useful for situations where only one type of rollup calculation is needed. For example, `rollup_rate(requests_total[5m], "max")`.
