Adding SNMP traps to rubygod?

[rubymono]

Greetings,

I am interested in having rubygod send SNMP traps on events, has anyone else implemented this or have any suggestions on how best to implement? Thanks for any thoughts

There are of course several ways to do this. Here are some meanderings.

1) Use God's syslog output and rsyslog's omsnmp module. Done with a little bit of config of rsyslog

2) Write some code

 a) gem install snmp

 b) Read http://snmplib.rubyforge.org/svn/trunk/lib/snmp/manager.rb

 c) Create something like this in the config file (note: not tested, just out of my head)

# Define the custom Syslogger event contact handler

require 'snmp'

module God

  module Contacts

    class SNMPTrap < Contact

      class << self

        attr_accessor :level, :message

      end

      def valid?

        valid = true

        valid &= complain("Attribute 'level' must be specified", self) unless arg(:level)

        valid

      end

      attr_accessor :level, :message

      def notify(message, time, priority, category, host)

        SNMPTrapObjectThingy.doSomething(arg(:level), arg(:message) || message)

      rescue Object => e

        applog(nil, :info, "SNMPTrap failed")

        applog(nil, :debug, e.backtrace.join("\n"))

      end

    end

  end

end

God.contact(:SNMPTrap) do |c|

  c.name = 'Log_Flapping'

  c.message = "Thing is restarting too quickly"

  c.level = :warn

end

God.watch do |w|

  w.lifecycle do |on|

    on.condition(:flapping) do |c|

      c.notify = 'Log_Flapping'

    end

  end

end
