Where/What File to change disk usage percentage for notification email

1

Had something run away from me on my FreePBX distro and got several emails notifying me of the problem and low disk usage at about 70% and several more up to close to 100% over the course of a few hours.

I Googled and STFed and coldn’t find the info. I would like to know where/what file can be modified to decrease this threshold to like 50% before an email is sent. I would love more time to get to the system before it fills and crashed and being able to set these thresholds could be very beneficial.

Thanks in advance!

crontab -l -u asterisk suggests it is:-

/var/lib/asterisk/bin/storage.php

Personally I have long relied on “logwatch” which is highly cutomizable, in your case you might want to check

logwatch --service zz-disk_space

after editing

/usr/share/logwatch/default.conf/services/zz-disk_space.conf

either ad-hoc or run it as a cron job outside the daily logwatch cron job

However bear in mind that 69G in three hours is a problem not many experience. :slight_smile:

Dicko, you are a true guru! How do you learn all this?

Thanks for the info. I will poke around and play around! And oh yes! That was a fast fill up. So far today, rock steady!

PS. In looking at storage.php, it appears to be compiled or obfuscated.

Here’s a cron job from Scotty

DILITHIUM=$(df -h /|tail -1|sed 's/^.* \([0-9]*\)%.*/\1/');if [ $DILITHIUM -ge 50 ];then echo -n| mail -s "Captain, we got a problem, dilithium crystals are less than $(( 100 - $DILITHIUM))%" [email protected];fi
