Supported Telegraf aggregator plugins
The BasicStats (
basicstats) aggregator plugin gives count, max, min, mean, s2(variance), and stdev for a set of values, emitting the aggregate every period seconds.
The Histogram (
histogram) aggregator plugin creates histograms containing the counts of field values within a range.
Values added to a bucket are also added to the larger buckets in the distribution. This creates a cumulative histogram.
Like other Telegraf aggregators, the metric is emitted every period seconds. Bucket counts however are not reset between periods and will be non-strictly increasing while Telegraf is running.
The MinMax (
minmax) aggregator plugin aggregates min and max values of each field it sees, emitting the aggegrate every period seconds.
