Puppet Class: prometheus::node_pinger

Defined in:

Overview

Simple latency statistics pinging a different nodes

Parameters:

  • nodes_to_ping_regular_mtu (Hash[Stdlib::Fqdn, Stdlib::IP::Address::Nosubnet]) (defaults to: {})
  • nodes_to_ping_jumbo_mtu (Hash[Stdlib::Fqdn, Stdlib::IP::Address::Nosubnet]) (defaults to: {})
  • ensure (Wmflib::Ensure) (defaults to: 'present')
  • outfile (Stdlib::Unixpath) (defaults to: '/var/lib/prometheus/node.d/node_pinger.prom')
