Antwort: Re: check_snmp_int - No usable data on file

[Radu.Popa at technomatic.de]

Hello Jim and thanks for your answer!

I have double checked the files in /tmp created by the script and they are 
all owned by nagios group and nagios user, so fully writeable.

The actual check interval of the port is 20 seconds ( I check every 2 
units and the time unit is 10 seconds in the nagios.cfg). The correct 
value for the plugin time is in this case 20s?

I will give it a try with making the normal check interval and retry 
interval at the same value.

Cheers!

I believe that with check_interval of 2 minutes, you need -d 120.

With the plugin working in this way, you need to set your
retry_interval to be the same as your check_interval, otherwise the -d
value won't be correct for the interval when the check starts
retrying!

Note that in Nagios 3, the syntax "normal_check_interval" and
"retry_check_interval" is deprecated.  The equivalent directives are
now simply "check_interval" and "retry_interval".  See:
http://nagios.sourceforge.net/docs/nagioscore/3/en/objectdefinitions.html#service


If you are still having problems with the "No usable data on file"
error, make sure the files created by the plugin are writeable by the
user 'nagios'  (if I recall they are under /tmp or maybe /var/tmp - I
don't have my nagios system to hand to check for sure).  If you have
been testing the plugin from the command line while logged in as
another user, it's quite likely the files will have the wrong
ownership/permissions in which case you can simply delete them to let
nagios recreate them next time it runs the plugin.
