You should try to run the plugin as the user under which Nagios run (usually nagios).

In any case run it with the -verbose option to have more information:

$ /usr/lib64/nagios/plugins/check_updates -vvv --no-boot-check -t 200 -c 2

and post the output

Strange could you please tell me if you are really using version 1.3.4 as reported? In this case you should definitely update.

Otherwise can you please post the output of

    $ yum check-updates

    $ yum --security check-updates

Hello I have the same issue with check_updates in centos 5.6

[root@pc plugins]# /usr/lib64/nagios/plugins/check_updates -V
check_updates 1.6.3 [https://trac.id.ethz.ch/projects/nagios_plugins]

When I type in cmd:

[root@pc plugins]# /usr/lib64/nagios/plugins/check_updates --no-boot-check -t 200 -c 2
CHECK_UPDATES OK - no updates available | total_updates=0;0;2 security_updates=0;0;2

I get reply from script as shown above. I have declared new command in command.cfg:

define command{
        command_name    check_updates
        command_line    $USER1$/check_updates --no-boot-check -t 200 -c 2
        }

and i call check_update in localhost.cfg:

define service{
        use                             local-service         ; Name of service template to use
        host_name                       localhost
        service_description             System updates via yum
        check_command                   check_updates
        }

In nagios.debug i see that function check_update is beeing called properly:

Processing: '$USER1$/check_updates --no-boot-check -t 200 -c 2'
 Done.  Final output: '/usr/lib64/nagios/plugins/check_updates  --no-boot-check -t 200 -c 2'

I don`t know what else can be wrong, could You Help Me please ?
