VictoriaMetrics implements MetricsQL - query language inspired by [PromQL](https://prometheus.io/docs/prometheus/latest/querying/basics/).
It is backwards compatible with PromQL, so Grafana dashboards backed by Prometheus datasource should work the same after switching from Prometheus to VictoriaMetrics.
[Standalone MetricsQL package](https://godoc.org/github.com/VictoriaMetrics/VictoriaMetrics/lib/metricsql) can be used for parsing MetricsQL in external apps.
[Standalone MetricsQL package](https://godoc.org/github.com/VictoriaMetrics/metricsql) can be used for parsing MetricsQL in external apps.
The following functionality is implemented differently in MetricsQL comparing to PromQL in order to improve user experience:
* MetricsQL takes into account the previous point before the window in square brackets for range functions such as `rate` and `increase`.

// Package metricsql implements MetricsQL parser.
//
// This parser can parse PromQL. Additionally it can parse all the MetricsQL extensions.
// See https://github.com/VictoriaMetrics/VictoriaMetrics/wiki/MetricsQL for details about MetricsQL extensions.
//
// Usage:
//
// expr, err := metricsql.Parse(`sum(rate(foo{bar="baz"}[5m])) by (job)`)
// if err != nil {
// // parse error
// }
// // Now expr contains parsed MetricsQL as `*Expr` structs.

# metricsql
Package metricsql implements [MetricsQL](https://github.com/VictoriaMetrics/VictoriaMetrics/wiki/MetricsQL)
and [PromQL](https://medium.com/@valyala/promql-tutorial-for-beginners-9ab455142085) parser in Go.
### Usage
```go
expr, err := metricsql.Parse(`sum(rate(foo{bar="baz"}[5m])) by (job)`)
if err != nil {
// parse error
}
// Now expr contains parsed MetricsQL as `*Expr` structs.
// See Parse examples for more details.
```
See [docs](https://godoc.org/github.com/VictoriaMetrics/metricsql) for more details.
