BasicStats Aggregator Plugin

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

Configuration:

# 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","diff","rate","min","max","mean","non_negative_diff","non_negative_rate","stdev","s2","sum","interval"]

• stats
  • If not specified, then count, min, max, mean, stdev, and s2 are aggregated and pushed as fields. sum, diff and non_negative_diff 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_sum
  • field1_s2 (variance)
  • field1_stdev (standard deviation)
  • field1_interval (interval in nanoseconds)
