Puppet Class: prometheus::nic_saturation_exporter

Defined in:
modules/prometheus/manifests/nic_saturation_exporter.pp

Overview

class prometheus::nic_saturation_exporter

Deploys an exporter that polls network interface transmit/receive byte counters every second, and increments counters whenever utilization was too high in a one-second window. Catches micro-bursts of saturation that escape detection by normal monitoring (which has a 30-second window).

Parameters:

  • ensure (Wmflib::Ensure) (defaults to: 'present')
  • listen_address (Optional[Stdlib::Host]) (defaults to: undef)
