# BasicStats Aggregator Plugin

The BasicStats aggregator plugin give us count,max,min,mean,s2(variance), stdev for a set of values,
emitting the aggregate every `period` seconds.

### Configuration:

```toml
# Keep the aggregate basicstats of each metric passing through.
[[aggregators.basicstats]]
  ## General Aggregator Arguments:
  ## The period on which to flush & clear the aggregator.
  period = "30s"
  ## If true, the original metric will be dropped by the
  ## aggregator and will not get sent to the output plugins.
  drop_original = false
```

### Measurements & Fields:
