Nagios Support Forum

Hi,

We are currently migrating our hosts from 2012.R9 to the latest version of nagios.
We have a bunch of custom checks, and it appears most of them (all of them?) are failing.

example:
(No output on stdout) stderr: execvp(/usr/local/nagios/libexec/check_json, ...) failed. errno is 2: No such file or directory

Even though:

# ls -lah /usr/local/nagios/libexec/check_json
-rwxr-xr-x 1 apache nagios 2,4K Svi 6 2015 /usr/local/nagios/libexec/check_json

In the commands conf we have:

define command {
command_name check_json
command_line $USER1$/check_json -h $HOSTADDRESS$ -p $ARG1$ -u $ARG2$
}

And service is defined within the hosts properly.

When I execute it via command line, it works fine:

root@nagios:/usr/local/nagios/libexec
# ruby ./check_json -h 10.11.12.13 -p 8080 -u /check
Service is running

Not sure what's the issue here. Any help would be appreciated.

So, this happened.

This is a ruby script, and location was specified as "#!/usr/local/bin/ruby" , while this machine was running /usr/bin/ruby.
Error is kind of misleading imho, but at least we figured it out.

Thanks for letting us know what the fix was. Would you like us to close this thread?

Hi,

Sorry for the late reply.
Sure thing - it's resolved now.

Closing this up!
