Error while running plugin

Hi Guys,

I'm currently having an issue with one of my plugins.

Nagios states the following:
(Return code of 127 is out of bounds - plugin may be missing)

On CLI the following error appears when i run "./check-cisco.pl -H xx.xx.xx.xx -C public -t fan"
: No such file or directory

Running "vi /usr/local/nagios/libexec/check-cisco.pl" opens the file.


[root@nagios libexec]# ls
centreon check_ifstatus check_rpc
check_apt check_imap check_sensors
check_breeze check_ircd check_simap
check_by_ssh check_jabber check_smtp
check_cisco.pl check_load check_snmp

Source script: https://exchange.nagios.org/directory/P ... st/details

Any ideas?

What are the permissions on the file?

Code: Select all

ls -l

Maybe you should try a _ instead of -

Code: Select all

"./check_cisco.pl -H xx.xx.xx.xx -C public -t fan"

"./check_cisco.pl -H xx.xx.xx.xx -C public -t fan"
Tried both, because i added them with - and _
Original is -

Still not working

And on the command line?

Both check-cisco.pl and check_cisco.pl are giving me the error ": No such file or directory" after pressing enter.
Seems like it's referring to a folder, which does not exist.

Maybe you could try running the script without any arguments?

Code: Select all

/usr/local/nagios/libexec/check-cisco.pl
or

Code: Select all

/usr/local/nagios/libexec/check_cisco.pl
Or if that fails try:

Code: Select all

strace /usr/local/nagios/libexec/check-cisco.pl
or

Code: Select all

strace /usr/local/nagios/libexec/check_cisco.pl
And post that output

Seems like it's missing some folders. Any idea how to fix this?

Can you run the following on your Nagios server and post the output?

Code: Select all

ls -l /usr/local/nagios/libexec/
which env
perl -V
All times are UTC-05:00
