I/O UNKNOWN Unable to save current stats for later usage

When run Locally
======================
[root@viz-nagios-server-sc ~]# /usr/local/nagios/libexec/check_mio -d sda -w 200,2000,52428800,52428800 -c 400,4000,104857600,104857600

Owner's Reply:

This happens when you run the script as root for the first time and then try to run it as different user.
Just delete the temp file "/var/tmp/check_mio.sda" or chown it to the
user running NRPE.
