Nagios::Plugin::DieNicely - Die in a Nagios output compatible way


  use Nagios::Plugin::DieNicely;

  ... your plugin code goes here ...

  use Nagios::Plugin::DieNicely 'WARNING';

  ... now if you die, you will get a Nagios WARNING state ...


When your Nagios plugins, or the modules that they use raise an unhandled exception with die, croak or confess, the exception gets lost, and Nagios treats the output as an UNKNOWN state with no output from the plugin, as STDERR gets discarded by Nagios.

This module overrides perl's default behaviour of using exit code 255 and printing the error to STDERR (not Nagios friendly). Just using for exit code 2 (Nagios CRITICAL), and outputing the error to STDOUT with "CRITICAL - " prepended to the exception. Note that you can change the CRITICAL for WARNING, or even OK (not recommended)


Just use the module. If you want a Nagios error code other that CRITICAL, then use the module passing one of: WARNING, OK, UNKNOWN. CRITICAL can be passed too (just for completeness).

  use Nagios::Plugin::DieNicely 'WARNING';
  use Nagios::Plugin::DieNicely 'UNKNOWN';
  use Nagios::Plugin::DieNicely 'CRITICAL';
  use Nagios::Plugin::DieNicely 'OK';


 - Get the shortname of the module through Nagios::Plugin if it is beeing used
 - Issue perl warnings to STDOUT, and possbily issue WARNING or CRITICAL
