DESCRIPTION ^

POE::Component::Client::NSCA is a POE component that implements send_nsca functionality. This is the client program that is used to send service check information from a remote machine to an nsca daemon on the central machine that runs Nagios.

It is based in part on code shamelessly borrowed from Net::Nsca and optionally supports encryption using the Mcrypt module.

CONSTRUCTOR ^

send_nsca

Takes a number of parameters:

  'host', the hostname or IP address to connect to, mandatory;
  'event', the event handler in your session where the result should be sent, mandatory;
  'password', password that should be used to encrypt the packet, mandatory;
  'encryption', the encryption method to use, see below, mandatory;
  'message', a hashref containing details of the message to send, see below, mandatory;
  'session', optional if the poco is spawned from within another session;
  'port', the port to connect to, default is 5667;
  'context', anything you like that'll fit in a scalar, a ref for instance;
  'timeout', number of seconds to wait for socket timeouts, default is 10;

The 'session' parameter is only required if you wish the output event to go to a different session than the calling session, or if you have spawned the poco outside of a session.

The 'encryption' method is an integer value indicating the type of encryption to employ:

       0 = None        (Do NOT use this option)
       1 = Simple XOR  (No security, just obfuscation, but very fast)

       2 = DES
       3 = 3DES (Triple DES)
       4 = CAST-128
       5 = CAST-256
       6 = xTEA
       7 = 3WAY
       8 = BLOWFISH
       9 = TWOFISH
       10 = LOKI97
       11 = RC2
       12 = ARCFOUR

       14 = RIJNDAEL-128
       15 = RIJNDAEL-192
       16 = RIJNDAEL-256

       19 = WAKE
       20 = SERPENT

       22 = ENIGMA (Unix crypt)
       23 = GOST
       24 = SAFER64
       25 = SAFER128
       26 = SAFER+

Methods 2-26 require that the Mcrypt module is installed.

The 'message' hashref must contain the following keys:

  'host_name', the host that this check is for, mandatory;
  'return_code', the result code for the check, mandatory;
  'plugin_output', the output from the check, mandatory;
  'svc_description', the service description ( required if this is a service not a host check );

The poco does it's work and will return the output event with the result.

OUTPUT EVENT ^

This is generated by the poco. ARG0 will be a hash reference with the following keys:

  'host', the hostname given;
  'message', the message that was sent;
  'context', anything that you specified;
  'success', indicates that the check was successfully sent to the NSCA daemon;
  'error', only exists if something went wrong;
