I do this automatically with a cron script.
This is an example

#!/bin/sh
w>/root/bin/df_info.txt
date>> /root/bin/df_info.txt
echo 'This is from My Brothers Machine!' >>/root/bin/df_info.txt
df -H>> /root/bin/df_info.txt
cat /root/bin/df_info.txt | mail -s 'Info from My Brothers Machine' 
you at somewhere.com

I am doing this as root but a regular user can do the same

'w' returns system uptime and load averages which get copied 
to  /root/bin/df_info.txt

'date' returns the date and is appended to  /root/bin/df_info.txt
notice the >> which appends


I then echo some text which gets appended

I then run 'df' which tells me what my harddrives are doing, that gets 
appended


cat the file and pipe it to the mail command


I run the script from cron

#Run some command every hour
*/60 * * * * /run/some/command

hope this helps
