VictoriaMetrics supports `__graphite__` pseudo-label for selecting time series with Graphite-compatible filters in [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html). For example, `{__graphite__="foo.*.bar"}` is equivalent to `{__name__=~"foo[.][^.]*[.]bar"}`, but it works faster and it is easier to use when migrating from Graphite to VictoriaMetrics. See [docs for Graphite paths and wildcards](https://graphite.readthedocs.io/en/latest/render_api.html#paths-and-wildcards). VictoriaMetrics also supports [label_graphite_group](https://docs.victoriametrics.com/MetricsQL.html#label_graphite_group) function for extracting the given groups from Graphite metric name.
The `__graphite__` pseudo-label supports e.g. alternate regexp filters such as `(value1|...|valueN)`. They are transparently converted to `{value1,...,valueN}` syntax [used in Graphite](https://graphite.readthedocs.io/en/latest/render_api.html#paths-and-wildcards). This allows using [multi-value template variables in Grafana](https://grafana.com/docs/grafana/latest/variables/formatting-multi-value-variables/) inside `__graphite__` pseudo-label. For example, Grafana expands `{__graphite__=~"foo.$bar.baz"}` into `{__graphite__=~"foo.(x|y).baz"}` if `$bar` template variable contains `x` and `y` values. In this case the query is automatically converted into `{__graphite__=~"foo.{x,y}.baz"}` before execution.
