#### Special match groups
When using regex, the match group `0` is the full match and can be used to attach labels to the metric.
Example:
```yaml
mappings:
- match: ".+"
match_type: regex
name: "$0"
labels:
statsd_metric_name: "$0"
```
If a metric `my.statsd_counter` is received, the metric name will **still** be mapped to `my_statsd_counter` (Prometheus compatible name).
But the metric will also have the label `statsd_metric_name` with the value `my.statsd_counter` (unchanged value).
Note: If you use the `match` like the example (i.e. `.+`), be aware that it will be a "catch-all" block. So it should come at the very end of the mapping list.
The same is not achievable with glob matching, for more details check [this issue](https://github.com/prometheus/statsd_exporter/issues/444).
