|
80 =head1 SYNOPSIS |
|
81 |
|
82 submit-via nsca --nsca-host {host} [options] -- {check} [check-options] |
|

|
84 =head1 DESCRIPTION |
|
85 |
|
86 This simple script submits the result of nagios check plugins to an NSCA |
|
87 receiver. The script does not send the result itself, it's merely a |
|
88 wrapper around C<send_nsca>. |
|

|
100 |
