example ruby for silencing checks in Sensu

jenkins_silence.rb

#!/usr/bin/env ruby
require 'em-http-request'
require 'json'

servers = ["mysql01", "rabbitmq01", 
           "riak01", "api01", "web01", 
           "widgets01", "app01", "app02"]
pending = servers.length

EM.run {
  servers.each do |server|
    request_options = {
      :body => {'timestamp' => Time.now.to_i}.to_json,
      :head => {'content-type' => 'application/json'} }
    http = EM::HttpRequest.new("http://sensuserver:8080/stash/silence/#{server}").post request_options
    http.callback {
      puts "#{server}\n#{http.response_header.status} - #{http.response.length} bytes\n"
      puts http.response
      pending -= 1
      puts pending
      EM.stop if pending == 0
    }
  end  

We run this from Jenkins to silence all checks for hosts in the servers array on a regular schedule. Another script is used to unsilence the same servers later.

Note, this silences every check on the listed hosts. You can also silence individual checks within hosts.
