NAME

Net::NSCA::Client::ServerConfig - Specify configuration data for the remote NSCA server

CONTENTS

VERSION

This documentation refers to version 0.009002

SYNOPSIS



  use Net::NSCA::Client::ServerConfig;

  # Specify the non-default server configuration
  my $config = Net::NSCA::Client::ServerConfig->new(
      max_hostname_length     => 100,
      max_description_length  => 128,
      max_pluginoutput_length => 3072, # 3 KiB!
  );

  # Create a new connection with the configuration
  my $connection = Net::NSCA::Client::Connection->new(
      remote_host   => nagios.example.net,
      server_config => $config,
  );

  # Create a new client with the configuration
  my $nsca = Net::NSCA::Client->new(
      remote_host   => nagios.example.net,
      server_config => $config,
  );

  # Data packets will adhere to the server configuration
  $nsca->send_report(
      hostname => web1.example.net,
      service  => MYSQL,
      message  => $plugin_output,
      status   => $Net::NSCA::Client::STATUS_OK,
  );



DESCRIPTION

When NSCA is compiled, there are constants that define the size of the packets that will be generated and accepted. If NSCA was compiled with custom values for these constants, then this module will allow the client to generate corresponding packets.

CONSTRUCTOR

This is fully object-oriented, and as such before any method can be used, the constructor needs to be called to create an object to work with.

    new

This will construct a new object.
new(%attributes) %attributes is a HASH where the keys are attributes (specified in the ATTRIBUTES section).
new($attributes) $attributes is a HASHREF where the keys are attributes (specified in the ATTRIBUTES section).

ATTRIBUTES



  # Get an attribute
  my $value = $object->attribute_name;



    initialization_vector_length

This specifies the byte length of the initialization vector in the initial packet as specified in the TRANSMITTED_IV_SIZE constant in common.h.

    max_description_length

This specifies the maximum description length in bytes as specified in the MAX_DESCRIPTION_LENGTH constant in common.h.

    max_hostname_length

This specifies the maximum host name length in bytes as specified in the MAX_HOSTNAME_LENGTH constant in common.h.

    max_service_message_length

This specifies the maximum service message (plugin output) length in bytes as specified in the MAX_PLUGINOUTPUT_LENGTH constant in common.h.

METHODS

    is_compatible_with

This takes another Net::NSCA::Client::ServerConfig instance and returns a Boolean specifying if the two server configurations are compatible with each other. This method is also accessible through an overloaded == and !=.

    pack_data_packet

This takes a HASHREF that specify the members of the C structure and the values to pack in each member. This will return a string that is the raw packed byte data.

    pack_initial_packet

This takes a HASHREF that specify the members of the C structure and the values to pack in each member. This will return a string that is the raw packed byte data.

    repack_data_packet

This takes the raw packet as the first argument and a HASHREF (as specified in pack_data_packet) as the second argument. The first argument (the raw packet) may be a scalar reference and the packet will be modified in place. The new raw packet or the same scalar reference will be returned, based on if the first argument was a scalar reference or not.



  # Repack by copying packet around
  my $no_crc32 = $packer->repack_data_packet($raw_packet, {crc32_value => 0});

  # Repack in place
  $packer->repack_data_packet(\$raw_packet, {crc32_value => 0});



    repack_initial_packet

This takes the raw packet as the first argument and a HASHREF (as specified in pack_initial_packet) as the second argument. The first argument (the raw packet) may be a scalar reference and the packet will be modified in place. The new raw packet or the same scalar reference will be returned, based on if the first argument was a scalar reference or not. See repack_data_packet for usage examples.

    unpack_data_packet

This takes the raw packet and returns a HASHREF of the C structure names and values. The raw packet may be given as a string or as a scalar reference.

    unpack_initial_packet

This takes the raw packet and returns a HASHREF of the C structure names and values. The raw packet may be given as a string or as a scalar reference.
