subroutine analyze_device {
  # do an inventory of the monitored device
  # collect information about all it's components
  # do a lot of things which require e.g. writing to temp files
  foreach (@components) {
    if (a certain problem found) {
      add_message(UNKNOWN, 'e.g. component xy could not be checked')
      # not good if the plugin is aborted here with nagios_exit 
    } elsif (another problem found) {
      add_message(CRITICAL, 'component xy failed')
    } else {
      add_message(OK, 'component xy fine')
  # cleanup temp files, maybe close database connections

my ($code, $message) = $plugin->check_messages(join_all => ', ');
$plugin->nagios_exit($code, $message);

My question was: why can i add messages with (OK, WARNING, CRITICAL) and
save them for the final output with nagios_exit, but not messages with an
UNKNOWN level?
For simple plugins, it might be ok to abort the execution with nagios_die in
case of an UNKNOWN situation. But if the plugin is a really big one, i would
like to treat UNKNOWN like any other error.
