Nagios monitoring script

[sts]

The following is a small script which we wrote to add failing oxidized nodes to our monitoring system. Might be worth to include it.

#!/usr/bin/env ruby

require 'open-uri'
require 'json'

critical = false
critical_nodes = []

json = JSON.load(open("http://localhost:8888/nodes.json"))
json.each do |node|
    last = node['last']
    if node['last']['status'] != 'success'
        critical_nodes << node['name']
        critical = true
    end
end

if critical
    puts 'Unable to backup: ' + critical_nodes.join(' ')
    exit 2
else
    puts 'Backup of all nodes completed successfully.'
    exit 0
end

Hi all,
I've made some adjustments to this script, I hope this could help :

#!/usr/bin/env ruby

## contrib via https://github.com/ytti/oxidized/issues/67

require 'open-uri'
require 'json'

critical = false
pending = false
critical_nodes = []
pending_nodes = []

begin
 json = JSON.parse(open("http://localhost:8888/nodes.json").read)
rescue
  puts '[CRIT] Unable to connect'
  exit 2
end
json.each do |node|
  if not node['last'].nil?
    if node['last']['status'] != 'success'
      critical_nodes << node['name']
      critical = true
    end
  else
    pending_nodes << node['name']
    pending = true
  end
end

if critical
  puts '[CRIT] Unable to backup: ' + critical_nodes.join(',')
  exit 2
elsif pending
  puts '[WARN] Pending backup: ' + pending_nodes.join(',')
  exit 1
else
  puts '[OK] Backup of all nodes completed successfully.'
  exit 0
end
