Scripting Nagios Custom checks is not that hard. Its a case of getting hold of group of commands, piping them and extracting the Status of a Service and then passing them as Variables with If THEN ELSE STATEMENTS, that in-turn informs Nagios the status of the Service being monitored.
I have scripted some Nagios Scripts which can be downloaded from BASH SCRIPTS section of the website. FELL Free to Play around with them and let me know / pass any comments on them.
Soo what are you waiting for GO Ahead and start downloading the One CLICK BASH Scripts now.
