This plugin was originally written 2007-03-24 by Wolfgang Wagner (http://www.waggy.at/nagios/capture_plugin.htm)
Copyright 2007 by Wolfgang Wagner. All rights reserved.
The plugin does not require any additional utilities, it simply wraps the original command, logs the output to a file and then returns the results and RC back to Nagios for handling.
Configuration:
Consider this command:
define command{
command_name check_ssl_cert
command_line /usr/lib/nagios/plugins/check_http -H '$HOSTADDRESS$' -I '$HOSTADDRESS$' -C10
}
In order to use the plugin, simple add /path/to/capture_output.pl in the beginning of the command, like so:
define command{
command_name check_ssl_cert
command_line /usr/lib/nagios/plugins/capture_output.pl /usr/lib/nagios/plugins/check_http -H '$HOSTADDRESS$' -I '$HOSTADDRESS$' -C10
}
Revised by Jess Portnoy on 2015-09-28, Changes:
- Exit with 3 [UNKNOWN] if cannot open() or close() file
- chmod file to 600 since it might contain sensitive info
- some cleanup

I spent few hour trying to figure it out why plugin that works just fine from the command line, does not work under centreon. And this script told me that sudo wants tty...
