Incorrect command line arguments supplied


i updated my nagios from 2.2 to 2.5 and my plugins to 1.4.3 and nrpe to 2.5.1 lastly but I checked everything out and all was fine with the 1.9 plugin but after I upgraded all my nrpe plugins I get this error Incorrect command line on the web portion of nagios this is linux OS, Fedora Core 4 is where nagios is installed, rest of the systems are all redhat/centos or fedora

From the server im monitoring from…
[[email protected] libexec]# ./check_nrpe -H -c check_load
OK - load average: 0.07, 0.18, 0.34|load1=0.070;10.000;15.000;0; load5=0.180;9.000;20.000;0; load15=0.340;8.000;18.000;0;

On that server

What seems to to be the problem?


and the services.cfg definition for the check that fails is what?


define service{
use generic-service
service_description System Load
is_volatile 0
check_period 24x7
max_check_attempts 4
normal_check_interval 4
retry_check_interval 2
contact_groups admins
notification_interval 120
notification_period workhours
notification_options w,u,c,r
check_command check_nrpe!check_load

Same as it was before? Does this new version require something different? This works on 1.9 NRPE and 1.4.3 plugins


googledd around havent found any answers… probably be switching back to 1.9 as it works just not 2.5.1 :frowning:


I don’t see anything wrong with it. All I can say is, try using an IP instead of


Works the same way… from the command line does it work fine, only nagios is having a problem executing it…who knows, not a programmer or anything :cry:

Reverted back to 1.9 just hope this version isn’t exploitable or anything :shock: as its the only one that works right


Is this set in nrpe.cfg?
It might help, but I doubt it.


yea its set to 0, tried it on 1 to but got

CHECK_NRPE: Error receiving data from daemon

when i swaped it back to 0 it still says the same thing I had to remove nrpe from the remote host and reinstall it again.

Ill have to start all over again im getting errors in the web portion saying i dont have permissions on nagios.cmd file when I did before i just changed apache versions is all because i wanted SSL support but that isn’t going to work so I think ill just save myself the headache and revert it all back the way it was before and close the book on it
