Subject
[Nagios-users] custom script






Dear all,

I created a custom check_log script, but I have a minor problem.

Attached is the script.

 From the machine that the script resides, all is ok.

NRPE config:
command[check_log_test]=/usr/local/nagios/check_logs rel1.repost.Aug2604

Output from machine running NRPE:

# /usr/local/nagios/check_logs rel1.repost.Aug2604
*** Repost of all pending candidates started at 10:00:01 PM *** : *** 
Repost finished at 10:27:49 PM ***
#

Good.

Output from machine running Nagios:

# /usr/lib/nagios/plugins/check_nrpe -H xxx.xxx.xxx.xxx -p 5666 -c 
check_log_test
File does not exist.

Not good.

The standard checks work all good, so I know there is nothing wrong with 
nagios / NRPE.

I had a look at the stock check_log, but could not find any help there.
Any help appreciated.
