|
|||
|
||||
The following functionality is implemented differently in MetricsQL compared to PromQL. This improves user experience:
|
||||
|
||||
* MetricsQL takes into account the previous point before the window in square brackets for range functions such as [rate](#rate) and [increase](#increase).
|
||||
This allows returning the exact results users expect for `increase(metric[$__interval])` queries instead of incomplete results Prometheus returns for such queries.
|
||||
* MetricsQL doesn't extrapolate range function results. This addresses [this issue from Prometheus](https://github.com/prometheus/prometheus/issues/3746).
|
||||
* MetricsQL takes into account the last [raw sample](https://docs.victoriametrics.com/keyconcepts/#raw-samples) before the lookbehind window
|
||||
in square brackets for [increase](#increase) and [rate](#rate) functions. This allows returning the exact results users expect for `increase(metric[$__interval])` queries
|
||||
instead of incomplete results Prometheus returns for such queries. Prometheus misses the increase between the last sample before the lookbehind window
|
||||
and the first sample inside the lookbehind window.
|
||||
* MetricsQL doesn't extrapolate [rate](#rate) and [increase](#increase) function results, so it always returns the expected results. For example, it returns
|
||||
integer results from `increase()` over slow-changing integer counter. Prometheus in this case returns unexpected fractional results,
|
||||
which may significantly differ from the expected results. This addresses [this issue from Prometheus](https://github.com/prometheus/prometheus/issues/3746).
|
||||
See technical details about VictoriaMetrics and Prometheus calculations for [rate](#rate)
|
||||
and [increase](#increase) [in this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1215#issuecomment-850305711).
|
||||
* MetricsQL returns the expected non-empty responses for [rate](#rate) with `step` values smaller than scrape interval.
|
||||
* MetricsQL returns the expected non-empty responses for [rate](#rate) function when Grafana or [vmui](https://docs.victoriametrics.com/#vmui)
|
||||
passes `step` values smaller than the interval between [raw samples](https://docs.victoriametrics.com/keyconcepts/#raw-samples)
|
||||
to [/api/v1/query_range](https://docs.victoriametrics.com/keyconcepts/#range-query).

See also [this blog post](https://www.percona.com/blog/2020/02/28/better-prometheus-rate-function-with-victoriametrics/).

See also [label_graphite_group](#label_graphite_group) function, which can be used for extracting the given groups from Graphite metric name.
|
||||
* Lookbehind window in square brackets may be omitted. VictoriaMetrics automatically selects the lookbehind window
|
||||
depending on the current step used for building the graph (e.g. `step` query arg passed to [/api/v1/query_range](https://docs.victoriametrics.com/keyConcepts.html#range-query)).
|

* Lookbehind window in square brackets for [rollup functions](#rollup-functions) may be omitted. VictoriaMetrics automatically selects the lookbehind window
|

depending on the `step` query arg passed to [/api/v1/query_range](https://docs.victoriametrics.com/keyConcepts.html#range-query)
|
||||
and the real interval between [raw samples](https://docs.victoriametrics.com/keyconcepts/#raw-samples) (aka `scrape_interval`).
|
||||
For instance, the following query is valid in VictoriaMetrics: `rate(node_network_receive_bytes_total)`.
|
||||
It is equivalent to `rate(node_network_receive_bytes_total[$__interval])` when used in Grafana.
|
||||
It is roughly equivalent to `rate(node_network_receive_bytes_total[$__interval])` when used in Grafana.
|
||||
The difference is documented in [rate() docs](#rate).
|
||||
* Numeric values can contain `_` delimiters for better readability. For example, `1_234_567_890` can be used in queries instead of `1234567890`.
|
||||
* [Series selectors](https://docs.victoriametrics.com/keyConcepts.html#filtering) accept multiple `or` filters. For example, `{env="prod",job="a" or env="dev",job="b"}`
|
||||
selects series with `{env="prod",job="a"}` or `{env="dev",job="b"}` labels.

* If the given [series selector](https://docs.victoriametrics.com/keyConcepts.html#filtering) returns multiple time series,

For example, `rate(http_requests_total)` is equivalent to `rate(http_requests_total[$__interval])` in Grafana.

It is also equivalent to `rate(http_requests_total[1i])`.

For example, `avg_over_time(temperature)` is automatically transformed to `avg_over_time(temperature[1i])`.

VictoriaMetrics performs the following implicit conversions for incoming queries before starting the calculations:
|
||||
|
||||
* If lookbehind window in square brackets is missing inside [rollup function](#rollup-functions),
|
||||
then `[1i]` is automatically added there. The `[1i]` means one `step` value, which is passed
|
||||
to [/api/v1/query_range](https://docs.victoriametrics.com/keyConcepts.html#range-query).
|
||||
It is also known as `$__interval` in Grafana. For example, `rate(http_requests_count)` is automatically transformed to `rate(http_requests_count[1i])`.
|
||||
* If lookbehind window in square brackets is missing inside [rollup function](#rollup-functions), then it is automatically set to the following value:
|
||||
- To `step` value passed to [/api/v1/query_range](https://docs.victoriametrics.com/keyConcepts.html#range-query) or [/api/v1/query](https://docs.victoriametrics.com/keyconcepts/#instant-query)
|
||||
for all the [rollup functions](#rollup-functions) except of [default_rollup](#default_rollup) and [rate](#rate). This value is known as `$__interval` in Grafana or `1i` in MetricsQL.
|
||||
For example, `avg_over_time(temperature)` is automatically transformed to `avg_over_time(temperature[1i])`.
|
||||
- To the `max(step, scrape_interval)`, where `scrape_interval` is the interval between [raw samples](https://docs.victoriametrics.com/keyconcepts/#raw-samples)
|
||||
for [default_rollup](#default_rollup) and [rate](#rate) functions. This allows avoiding unexpected gaps on the graph when `step` is smaller than `scrape_interval`.
|
||||
* All the [series selectors](https://docs.victoriametrics.com/keyConcepts.html#filtering),
|
||||
which aren't wrapped into [rollup functions](#rollup-functions), are automatically wrapped into [default_rollup](#default_rollup) function.
|
||||
Examples:
|
||||
* `foo` is transformed to `default_rollup(foo[1i])`
|
||||
* `foo + bar` is transformed to `default_rollup(foo[1i]) + default_rollup(bar[1i])`
|
||||
* `count(up)` is transformed to `count(default_rollup(up[1i]))`, because [count](#count) isn't a [rollup function](#rollup-functions) -
|
||||
* `foo` is transformed to `default_rollup(foo)`
|
||||
* `foo + bar` is transformed to `default_rollup(foo) + default_rollup(bar)`
|
||||
* `count(up)` is transformed to `count(default_rollup(up))`, because [count](#count) isn't a [rollup function](#rollup-functions) -
|
||||
it is [aggregate function](#aggregate-functions)
|
||||
* `abs(temperature)` is transformed to `abs(default_rollup(temperature[1i]))`, because [abs](#abs) isn't a [rollup function](#rollup-functions) -
|
||||
* `abs(temperature)` is transformed to `abs(default_rollup(temperature))`, because [abs](#abs) isn't a [rollup function](#rollup-functions) -
|
||||
it is [transform function](#transform-functions)
|
||||
* If `step` in square brackets is missing inside [subquery](#subqueries), then `1i` step is automatically added there.
|
||||
For example, `avg_over_time(rate(http_requests_total[5m])[1h])` is automatically converted to `avg_over_time(rate(http_requests_total[5m])[1h:1i])`.
|
||||
* If something other than [series selector](https://docs.victoriametrics.com/keyConcepts.html#filtering)
|
||||
is passed to [rollup function](#rollup-functions), then a [subquery](#subqueries) with `1i` lookbehind window and `1i` step is automatically formed.
|
||||
For example, `rate(sum(up))` is automatically converted to `rate((sum(default_rollup(up[1i])))[1i:1i])`.
|

For example, `rate(sum(up))` is automatically converted to `rate((sum(default_rollup(up)))[1i:1i])`.

|

|
||||
The following functionality is implemented differently in MetricsQL compared to PromQL. This improves user experience:
|
||||
|
||||
* MetricsQL takes into account the previous point before the window in square brackets for range functions such as [rate](#rate) and [increase](#increase).
|
||||
This allows returning the exact results users expect for `increase(metric[$__interval])` queries instead of incomplete results Prometheus returns for such queries.
|
||||
* MetricsQL doesn't extrapolate range function results. This addresses [this issue from Prometheus](https://github.com/prometheus/prometheus/issues/3746).
|
||||
* MetricsQL takes into account the last [raw sample](https://docs.victoriametrics.com/keyconcepts/#raw-samples) before the lookbehind window
|
||||
in square brackets for [increase](#increase) and [rate](#rate) functions. This allows returning the exact results users expect for `increase(metric[$__interval])` queries
|
||||
instead of incomplete results Prometheus returns for such queries. Prometheus misses the increase between the last sample before the lookbehind window
|
||||
and the first sample inside the lookbehind window.
|
||||
* MetricsQL doesn't extrapolate [rate](#rate) and [increase](#increase) function results, so it always returns the expected results. For example, it returns
|
||||
integer results from `increase()` over slow-changing integer counter. Prometheus in this case returns unexpected fractional results,
|
||||
which may significantly differ from the expected results. This addresses [this issue from Prometheus](https://github.com/prometheus/prometheus/issues/3746).
|
||||
See technical details about VictoriaMetrics and Prometheus calculations for [rate](#rate)
|
||||
and [increase](#increase) [in this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1215#issuecomment-850305711).
|
||||
* MetricsQL returns the expected non-empty responses for [rate](#rate) with `step` values smaller than scrape interval.
|
||||
* MetricsQL returns the expected non-empty responses for [rate](#rate) function when Grafana or [vmui](https://docs.victoriametrics.com/#vmui)

|

See also [label_graphite_group](#label_graphite_group) function, which can be used for extracting the given groups from Graphite metric name.
|
||||
* Lookbehind window in square brackets may be omitted. VictoriaMetrics automatically selects the lookbehind window
|
||||
depending on the current step used for building the graph (e.g. `step` query arg passed to [/api/v1/query_range](https://docs.victoriametrics.com/keyConcepts.html#range-query)).
|

* Lookbehind window in square brackets for [rollup functions](#rollup-functions) may be omitted. VictoriaMetrics automatically selects the lookbehind window
|

depending on the `step` query arg passed to [/api/v1/query_range](https://docs.victoriametrics.com/keyConcepts.html#range-query)
|
||||
and the real interval between [raw samples](https://docs.victoriametrics.com/keyconcepts/#raw-samples) (aka `scrape_interval`).
|
||||
For instance, the following query is valid in VictoriaMetrics: `rate(node_network_receive_bytes_total)`.
|
||||
It is equivalent to `rate(node_network_receive_bytes_total[$__interval])` when used in Grafana.
|
||||
It is roughly equivalent to `rate(node_network_receive_bytes_total[$__interval])` when used in Grafana.
|
||||
The difference is documented in [rate() docs](#rate).
|
||||
* Numeric values can contain `_` delimiters for better readability. For example, `1_234_567_890` can be used in queries instead of `1234567890`.
|
||||
* [Series selectors](https://docs.victoriametrics.com/keyConcepts.html#filtering) accept multiple `or` filters. For example, `{env="prod",job="a" or env="dev",job="b"}`
|
||||
selects series with either `{env="prod",job="a"}` or `{env="dev",job="b"}` labels.

The following functionality is implemented differently in MetricsQL compared to PromQL. This improves user experience:
|
||||
|
||||
* MetricsQL takes into account the previous point before the window in square brackets for range functions such as [rate](#rate) and [increase](#increase).
|
||||
This allows returning the exact results users expect for `increase(metric[$__interval])` queries instead of incomplete results Prometheus returns for such queries.
|
||||
* MetricsQL doesn't extrapolate range function results. This addresses [this issue from Prometheus](https://github.com/prometheus/prometheus/issues/3746).
|
||||
* MetricsQL takes into account the last [raw sample](https://docs.victoriametrics.com/keyconcepts/#raw-samples) before the lookbehind window
|
||||
in square brackets for [increase](#increase) and [rate](#rate) functions. This allows returning the exact results users expect for `increase(metric[$__interval])` queries
|
||||
instead of incomplete results Prometheus returns for such queries. Prometheus misses the increase between the last sample before the lookbehind window
|
||||
and the first sample inside the lookbehind window.
|
||||
* MetricsQL doesn't extrapolate [rate](#rate) and [increase](#increase) function results, so it always returns the expected results. For example, it returns
|
||||
integer results from `increase()` over slow-changing integer counter. Prometheus in this case returns unexpected fractional results,
|
||||
which may significantly differ from the expected results. This addresses [this issue from Prometheus](https://github.com/prometheus/prometheus/issues/3746).

|
||||
and [increase](#increase) [in this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1215#issuecomment-850305711).

* If lookbehind window in square brackets is missing, then MetricsQL automatically sets the lookbehind window
|
||||
to the interval between points on the graph (aka `step` query arg at [/api/v1/query_range](https://docs.victoriametrics.com/keyConcepts.html#range-query),
|
||||
`$__interval` value from Grafana or `1i` duration in MetricsQL).
|
||||
For example, `rate(http_requests_total)` is equivalent to `rate(http_requests_total[$__interval])` in Grafana.
|
||||
It is also equivalent to `rate(http_requests_total[1i])`.
|
||||
* If lookbehind window in square brackets is missing, then it is automatically set to the following value:
|
||||
- To `step` value passed to [/api/v1/query_range](https://docs.victoriametrics.com/keyConcepts.html#range-query) or [/api/v1/query](https://docs.victoriametrics.com/keyconcepts/#instant-query)
|
||||
for all the [rollup functions](#rollup-functions) except of [default_rollup](#default_rollup) and [rate](#rate). This value is known as `$__interval` in Grafana or `1i` in MetricsQL.
|
||||
For example, `avg_over_time(temperature)` is automatically transformed to `avg_over_time(temperature[1i])`.
|
||||
- To the `max(step, scrape_interval)`, where `scrape_interval` is the interval between [raw samples](https://docs.victoriametrics.com/keyconcepts/#raw-samples)
|
||||
for [default_rollup](#default_rollup) and [rate](#rate) functions. This allows avoiding unexpected gaps on the graph when `step` is smaller than `scrape_interval`.
|
||||
* Every [series selector](https://docs.victoriametrics.com/keyConcepts.html#filtering) in MetricsQL must be wrapped into a rollup function.
|
||||
Otherwise, it is automatically wrapped into [default_rollup](#default_rollup). For example, `foo{bar="baz"}`
|
||||
is automatically converted to `default_rollup(foo{bar="baz"}[1i])` before performing the calculations.
|
||||
is automatically converted to `default_rollup(foo{bar="baz"})` before performing the calculations.
|
||||
* If something other than [series selector](https://docs.victoriametrics.com/keyConcepts.html#filtering) is passed to rollup function,
|
||||
then the inner arg is automatically converted to a [subquery](#subqueries).
|
||||
* All the rollup functions accept optional `keep_metric_names` modifier. If it is set, then the function keeps metric names in results.

MetricsQL supports and extends PromQL subqueries. See [this article](https://valyala.medium.com/prometheus-subqueries-in-victoriametrics-9b1492b720b3) for details.

Any [rollup function](#rollup-functions) for something other than [series selector](https://docs.victoriametrics.com/keyConcepts.html#filtering) form a subquery.

Nested rollup functions can be implicit thanks to the [implicit query conversions](#implicit-query-conversions).

For example, `delta(sum(m))` is implicitly converted to `delta(sum(default_rollup(m[1i]))[1i:1i])`, so it becomes a subquery,

For example, `delta(sum(m))` is implicitly converted to `delta(sum(default_rollup(m))[1i:1i])`, so it becomes a subquery,

VictoriaMetrics performs the following implicit conversions for incoming queries before starting the calculations:

|
||||
* If lookbehind window in square brackets is missing inside [rollup function](#rollup-functions),
|
||||
then `[1i]` is automatically added there. The `[1i]` means one `step` value, which is passed
|
||||
to [/api/v1/query_range](https://docs.victoriametrics.com/keyConcepts.html#range-query).
|
||||
It is also known as `$__interval` in Grafana. For example, `rate(http_requests_count)` is automatically transformed to `rate(http_requests_count[1i])`.
|
||||
* If lookbehind window in square brackets is missing inside [rollup function](#rollup-functions), then it is automatically set to the following value:
|
||||
- To `step` value passed to [/api/v1/query_range](https://docs.victoriametrics.com/keyConcepts.html#range-query) or [/api/v1/query](https://docs.victoriametrics.com/keyconcepts/#instant-query)
|
||||
for all the [rollup functions](#rollup-functions) except of [default_rollup](#default_rollup) and [rate](#rate). This value is known as `$__interval` in Grafana or `1i` in MetricsQL.
|
||||
For example, `avg_over_time(temperature)` is automatically transformed to `avg_over_time(temperature[1i])`.
|
||||
- To the `max(step, scrape_interval)`, where `scrape_interval` is the interval between [raw samples](https://docs.victoriametrics.com/keyconcepts/#raw-samples)
|
||||
for [default_rollup](#default_rollup) and [rate](#rate) functions. This allows avoiding unexpected gaps on the graph when `step` is smaller than `scrape_interval`.
|
||||
* All the [series selectors](https://docs.victoriametrics.com/keyConcepts.html#filtering),
|
||||
which aren't wrapped into [rollup functions](#rollup-functions), are automatically wrapped into [default_rollup](#default_rollup) function.
|
||||
Examples:
|
||||
* `foo` is transformed to `default_rollup(foo[1i])`
|
||||
* `foo + bar` is transformed to `default_rollup(foo[1i]) + default_rollup(bar[1i])`
|
||||
* `count(up)` is transformed to `count(default_rollup(up[1i]))`, because [count](#count) isn't a [rollup function](#rollup-functions) -
|
||||
* `foo` is transformed to `default_rollup(foo)`
|
||||
* `foo + bar` is transformed to `default_rollup(foo) + default_rollup(bar)`
|
||||
* `count(up)` is transformed to `count(default_rollup(up))`, because [count](#count) isn't a [rollup function](#rollup-functions) -
|
||||
it is [aggregate function](#aggregate-functions)
|
||||
* `abs(temperature)` is transformed to `abs(default_rollup(temperature[1i]))`, because [abs](#abs) isn't a [rollup function](#rollup-functions) -
|
||||
* `abs(temperature)` is transformed to `abs(default_rollup(temperature))`, because [abs](#abs) isn't a [rollup function](#rollup-functions) -
|
||||
it is [transform function](#transform-functions)
|
||||
* If `step` in square brackets is missing inside [subquery](#subqueries), then `1i` step is automatically added there.
|
||||
For example, `avg_over_time(rate(http_requests_total[5m])[1h])` is automatically converted to `avg_over_time(rate(http_requests_total[5m])[1h:1i])`.
|
||||
* If something other than [series selector](https://docs.victoriametrics.com/keyConcepts.html#filtering)
|
||||
is passed to [rollup function](#rollup-functions), then a [subquery](#subqueries) with `1i` lookbehind window and `1i` step is automatically formed.
|
||||
For example, `rate(sum(up))` is automatically converted to `rate((sum(default_rollup(up[1i])))[1i:1i])`.
|
||||
For example, `rate(sum(up))` is automatically converted to `rate((sum(default_rollup(up)))[1i:1i])`.
