# Basic Statistics Aggregator Plugin

This plugin computes basic statistics such as counts, differences, minima, maxima, mean values, non-negative differences etc. for a set of metrics and emits these statistical values every `period`.

**Introduced in:** Telegraf v1.5.0 **Tags:** statistics **OS support:** all

## Global configuration options

Plugins support additional global and plugin configuration settings for tasks such as modifying metrics, tags, and fields, creating aliases, and configuring plugin ordering. See [CONFIGURATION.md](/telegraf/v1/configuration/#plugins) for more details.

## Configuration

```toml
# Keep the aggregate basicstats of each metric passing through.
[[aggregators.basicstats]]
  ## 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

  ## Configures which basic stats to push as fields
  # stats = ["count","min","max","mean","variance","stdev"]
```

-   stats
    -   If not specified, then `count`, `min`, `max`, `mean`, `stdev`, and `s2` are aggregated and pushed as fields. Other fields are not aggregated by default to maintain backwards compatibility.
    -   If empty array, no stats are aggregated

## Measurements & Fields

-   measurement1
    -   field1\_count
    -   field1\_diff (difference)
    -   field1\_rate (rate per second)
    -   field1\_max
    -   field1\_min
    -   field1\_mean
    -   field1\_non\_negative\_diff (non-negative difference)
    -   field1\_non\_negative\_rate (non-negative rate per second)
    -   field1\_percent\_change
    -   field1\_sum
    -   field1\_s2 (variance)
    -   field1\_stdev (standard deviation)
    -   field1\_interval (interval in nanoseconds)
    -   field1\_last (last aggregated value)
    -   field1\_first (first aggregated value)

## Tags

No tags are applied by this aggregator.
