## tip
* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): add support for `@` modifier, which is enabled by default in Prometheus starting from [Prometheus v2.33.0](https://github.com/prometheus/prometheus/pull/10121). See [these docs](https://prometheus.io/docs/prometheus/latest/querying/basics/#modifier) and [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1348). VictoriaMetrics extends `@` modifier with the following additional features:
* It can contain arbitrary expression. For example, `foo @ (end() - 1h)` would return `foo` value at `end - 1 hour` timestamp on the selected time range `[start ... end]`. Another example: `foo @ now() - 10m` would return `foo` value 10 minutes ago from the current time.
* It can be put everywhere in the query. For example, `sum(foo) @ start()` would calculate `sum(foo)` at `start` timestamp on the selected time range `[start ... end]`.
* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): add support for optional `keep_metric_names` modifier, which can be applied to all the [rollup functions](https://docs.victoriametrics.com/MetricsQL.html#rollup-functions) and [transform functions](https://docs.victoriametrics.com/MetricsQL.html#transform-functions). This modifier prevents from deleting metric names from function results. For example, `rate({__name__=~"foo|bar"}[5m]) keep_metric_names` leaves `foo` and `bar` metric names in `rate()` results. This feature provides an additional workaround for [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/949).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add support for Kubernetes service discovery in the current namespace in the same way as [Prometheus does](https://github.com/prometheus/prometheus/pull/9881). For example, the following config limits pod discovery to the namespace where vmagent runs:
```yaml
scrape_configs:
- job_name: 'kubernetes-pods'
kubernetes_sd_configs:
- role: pod
namespaces:
own_namespace: true
```
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add `__meta_kubernetes_node_provider_id` label for discovered Kubernetes nodes in the same way as [Prometheus does](https://github.com/prometheus/prometheus/pull/9603).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): log error message when remote storage returns 400 or 409 http errors. This should simplify detection and debugging of this case. See [this issue](vmagent_remotewrite_packets_dropped_total).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): expose `promscrape_stale_samples_created_total` metric for monitoring the total number of created stale samples when scraping Prometheus targets. See [these docs](https://docs.victoriametrics.com/vmagent.html#prometheus-staleness-markers) for the information on when stale samples (aka staleness markers) can be created.
* FEATURE: [vmrestore](https://docs.victoriametrics.com/vmrestore.html): store `restore-in-progress` file in `-dst` directory while `vmrestore` is running. This file is automatically deleted when `vmrestore` is successfully finished. This helps detecting incompletely restored data on VictoriaMetrics start. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1958).
* FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): print the last sample timestamp when the data migration is interrupted either by user or by error. This helps continuing the data migration from the interruption moment. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1236).
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): expose `vmalert_remotewrite_total` metric at `/metrics` page. This makes possible calculating SLOs for error rate during writing recording rules and alert state to `-remoteWrite.url` with the query `vmalert_remotewrite_errors_total / vmalert_remotewrite_total`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2040). Thanks to @afoninsky .
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add `stripPort` template function in the same way as [Prometheus does](https://github.com/prometheus/prometheus/pull/10002).
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add `parseDuration` template function in the same way as [Prometheus does](https://github.com/prometheus/prometheus/pull/8817).
* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): add `stale_samples_over_time(m[d])` function for calculating the number of [staleness marks](https://docs.victoriametrics.com/vmagent.html#prometheus-staleness-markers) for time series `m` over the duration `d`. This function may be useful for detecting flapping metrics at scrape targets, which periodically disappear and then appear again.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): make sure that `vmagent` replicas scrape the same targets at different time offsets when [replication is enabled in vmagent clustering mode](https://docs.victoriametrics.com/vmagent.html#scraping-big-number-of-targets). This guarantees that the [deduplication](https://docs.victoriametrics.com/#deduplication) consistently leaves samples from the same `vmagent` replica.
* BUGFIX: return the proper response stub from `/api/v1/query_exemplars` handler, which is needed for Grafana v8+. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1999).
* BUGFIX: [vmctl](https://docs.victoriametrics.com/vmctl.html): fix a few edge cases and improve migration speed for OpenTSDB importer. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2019).
* BUGFIX: fix possible data race when searching for time series matching `{key=~"value|"}` filter over time range covering multipe days. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2032). Thanks to @waldoweng for the provided fix.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): do not send staleness markers on graceful shutdown. This follows Prometheus behavior. See [this comment](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2013#issuecomment-1006994079).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly set `__address__` label in `dockerswarm_sd_config`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2038). Thanks to @ashtuchkin for the fix.

- Graphite-compatible filters can be passed via `{__graphite__="foo.*.bar"}` syntax. See [these docs](https://docs.victoriametrics.com/#selecting-graphite-metrics). VictoriaMetrics also can be used as Graphite datasource in Grafana. See [these docs](https://docs.victoriametrics.com/#graphite-api-usage) for details. 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://prometheus.io/docs/prometheus/latest/querying/api/#range-queries)). 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[$__interval])` when used in Grafana.
- [Aggregate functions](#aggregate-functions) accept arbitrary number of args. For example, `avg(q1, q2, q3)` would return the average values for every point across time series returned by `q1`, `q2` and `q3`.
- [@ modifier](https://prometheus.io/docs/prometheus/latest/querying/basics/#modifier) can be put anywhere in the query. For example, `sum(foo) @ end()` calculates `sum(foo)` at the `end` timestamp of the selected time range `[start ... end]`.
- Arbitrary subexpression can be used as [@ modifier](https://prometheus.io/docs/prometheus/latest/querying/basics/#modifier). For example, `foo @ (end() - 1h)` calculates `foo` at the `end - 1 hour` timestamp on the selected time range `[start ... end]`.
- [offset](https://prometheus.io/docs/prometheus/latest/querying/basics/#offset-modifier), lookbehind window in square brackets and `step` value for [subquery](#subqueries) may refer to the current step aka `$__interval` value from Grafana with `[Ni]` syntax. For instance, `rate(metric[10i] offset 5i)` would return per-second rate over a range covering 10 previous steps with the offset of 5 steps.
- [offset](https://prometheus.io/docs/prometheus/latest/querying/basics/#offset-modifier) may be put anywere in the query. For instance, `sum(foo) offset 24h`.
- [offset](https://prometheus.io/docs/prometheus/latest/querying/basics/#offset-modifier) may be negative. For example, `q offset -1h`.
- Lookbehind window in square brackets and [offset](https://prometheus.io/docs/prometheus/latest/querying/basics/#offset-modifier) may be fractional. For instance, `rate(node_network_receive_bytes_total[1.5m] offset 0.5d)`.
- The duration suffix is optional. The duration is in seconds if the suffix is missing. For example, `rate(m[300] offset 1800)` is equivalent to `rate(m[5m]) offset 30m`.
- The duration can be placed anywhere in the query. For example, `sum_over_time(m[1h]) / 1h` is equivalent to `sum_over_time(m[1h]) / 3600`.

- `ifnot` binary operator. `q1 ifnot q2` removes values from `q1` for existing values from `q2`.
- String literals may be concatenated. This is useful with `WITH` templates: `WITH (commonPrefix="long_metric_prefix_") {__name__=commonPrefix+"suffix1"} / {__name__=commonPrefix+"suffix2"}`.
- `WITH` templates. This feature simplifies writing and managing complex queries. Go to [WITH templates playground](https://play.victoriametrics.com/promql/expand-with-exprs) and try it.
- `keep_metric_names` modifier can be applied to all the [rollup functions](#rollup-functions) and [transform functions](#transform-functions). This modifier prevents from dropping metric names in function results. For example, `rate({__name__=~"foo|bar"}[5m]) keep_metric_names` leaves `foo` and `bar` metric names in the resulting time series.
## MetricsQL functions
@ -70,6 +72,7 @@ MetricsQL provides the following functions:
* 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://prometheus.io/docs/prometheus/latest/querying/api/#range-queries), `$__interval` value from Grafana or `1i` duration in MetricsQL). For example, `rate(http_requests_total)` is equivalent to `rate(http_requests_total[$__interval])` in Grafana. It is also equivalent to `rate(http_requests_total[1i])`.
* Every [series selector](https://prometheus.io/docs/prometheus/latest/querying/basics/#time-series-selectors) 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.
* If something other than [series selector](https://prometheus.io/docs/prometheus/latest/querying/basics/#time-series-selectors) 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. For example, `rate({__name__=~"foo|bar}[5m]) keep_metric_names` leaves `foo` and `bar` metric names in results.

### Transform functions
**Transform functions** calculate transformations over rollup results. For example, `abs(delta(temperature[24h]))` calculates the absolute value for every point of every time series returned from the rollup `delta(temperature[24h])`. Additional details:
* If transform function is applied directly to a [series selector](https://prometheus.io/docs/prometheus/latest/querying/basics/#time-series-selectors), then the [default_rollup()](#default_rollup) function is automatically applied before calculating the transformations. For example, `abs(temperature)` is implicitly transformed to `abs(default_rollup(temperature[1i]))`.
* All the transform functions accept optional `keep_metric_names` modifier. If it is set, then the function doesn't drop metric names from the resulting time series. For example, `ln({__name__=~"foo|bar"}) keep_metric_names` leaves `foo` and `bar` metric names in results.
