I had a problem proxying on Redhat.

I forgot that SELinux can be troublesome:

Simple disk space alert

09 Apr 2014

We had a need to get alerts in case we are close to running out of disk space on multiple servers but we didn’t want to over complicate it with heavy processes and monitoring. My solution:

#!/bin/bash
CURRENT=$(df /u01 | grep /u01 | awk '{ print $4}' | sed 's/%//g')
THRESHOLD=1000000
TO=\
user1@example.com \
user2@example.com

if [ "$CURRENT" -lt "$THRESHOLD" ] ; then
mail -s 'Disk Space Alert' $TO << EOF
/u01 partition is running low on disk space. $CURRENT bytes left.
EOF
