Odd Problem with check_yum on one server...

[Sean Alderman]

I apologize... I should have pasted that, but I thought the fact that I
could execute the check_yum script as the nrpe user on the host with the
problem would have implied that it functions as expected.  Yum is located
where we would expect it to be on a standard CentOS machine.

[root at test ~]# rpm -qa|grep yum
> yum-3.2.29-40.el6.centos.noarch
> yum-utils-1.1.30-14.el6.noarch
> yum-metadata-parser-1.1.2-16.el6.x86_64
> yum-plugin-fastestmirror-1.1.30-14.el6.noarch
> yum-plugin-security-1.1.30-14.el6.noarch
> [root at test ~]# which yum
> /usr/bin/yum
>

Thanks,
