Barkfile example

monitor "Check load avg", :type=>"metric alert" do
  query "avg(last_5m):avg:ddstat.load_avg.1m{host:i-XXXXXXXX} > 1"
  message "@winebarrel@example.net"
  tags ["load", "host", "example"]
  options do
    locked false
    new_host_delay 300
    notify_no_data true
    no_data_timeframe 2
    notify_audit true
    silenced({})
  end
end

Use template

template "cpu template" do
  query "avg(last_5m):avg:#{context.target}.load_avg.1m{host:i-XXXXXXXX} > 1"
  message context.message
  options do
    locked false
    new_host_delay 300
    notify_no_data true
    no_data_timeframe 2
    notify_audit true
    silenced({})
  end
end

monitor "Check load avg", :type=>"metric alert" do
  context.message = "@winebarrel@example.net"
  include_template "cpu template", :target=>"ddstat"
end

template "basic monitor" do
  monitor "#{context.target} cpu" do
    query "avg(last_5m):avg:#{context.target}.load_avg.1m{host:i-XXXXXXXX} > 1"
    ...
  end

  # any other monitor
  monitor ...
end

"myhost".tap do |host|
  include_template "basic monitor", :target=>host
  include_template "mysql monitor", :target=>host
  ...
end
