README

Dedup Processor Plugin

Filter metrics whose field values are exact repetitions of the previous values.

Configuration

# Filter metrics with repeating field values
[[processors.dedup]]
  ## Maximum time to suppress output
  dedup_interval = "600s"

Example

- cpu,cpu=cpu0 time_idle=42i,time_guest=1i
- cpu,cpu=cpu0 time_idle=42i,time_guest=2i
- cpu,cpu=cpu0 time_idle=42i,time_guest=2i
- cpu,cpu=cpu0 time_idle=44i,time_guest=2i
- cpu,cpu=cpu0 time_idle=44i,time_guest=2i
+ cpu,cpu=cpu0 time_idle=42i,time_guest=1i
+ cpu,cpu=cpu0 time_idle=42i,time_guest=2i
+ cpu,cpu=cpu0 time_idle=44i,time_guest=2i
