How to watch disk usage and send mail in pfSense.

Hi,
I wrote a blog post about how to watch disk usage of pfsense and when disk usage become greater than 90%, I send mail to user that the user will be aware that the pfsense disk usage at critical point and user needs to work on it to make disk works again before system get crashed.

What are you doing that would cause disk usage to grow so much?

@jknott Well, you can find the +500MB (define size) files on your pfsense file system by using find command like this.
pfsense# find / -type f -size +500MActually "find" command would be fine to find big files on your pfsense. That's all I would do to find big files on my system.
Also the following command will show you human readable size of txt file
du -sh filename.txt -
I did and nothing showed up. With something like a firewall, there shouldn't be such an increase in disk usage, as you might get with a regular computer. Maybe you should try finding out where those large files are coming from.
