Hi, @Eskobar
1st I would create a smart computer group with criteria "Drive Capacity MB" (you'll find it at the advanced criteria) less than *whatever you want in Megabyte*
Then you have 2 options:
- you can run an action right out oft this smart group (for example send an email)
- you can create a policy, that will show a messagebox on the computers in that group with a text. You have to scope that policy to the smart computer group
- either you will do this message box via an own script or you can configure the message at the policy itself at the "user interaction". I use an own script for this. (I did a script "message4u" with parameters for a headline and a text area, see my screenshots below)
This is what I use
#!/bin/sh
# Display free space
FreeSpace=$( /usr/sbin/diskutil info / | /usr/bin/grep -E 'Free Space|Available Space|Container Free Space' | /usr/bin/awk -F ":\s*" '{ print $2 }' | awk -F "(" '{ print $1 }' | xargs )
FreeBytes=$( /usr/sbin/diskutil info / | /usr/bin/grep -E 'Free Space|Available Space|Container Free Space' | /usr/bin/awk -F "(\\\(| Bytes\\\))" '{ print $2 }' )
DiskBytes=$( /usr/sbin/diskutil info / | /usr/bin/grep -E 'Total Space' | /usr/bin/awk -F "(\\\(| Bytes\\\))" '{ print $2 }' )
FreePercentage=$(echo "scale=2; $FreeBytes*100/$DiskBytes" | bc)
diskSpace="Disk Space: $FreeSpace free (${FreePercentage}% available)"
## Information ##
displayInfo="----------------------------------------------
Your Disk Space is Running Low
$diskSpace
Whatever you want here
----------------------------------------------"
## Disk Space Message ##
diskmsg="button returned of (display dialog \"$displayInfo\" with title \"Disk Space\" with icon file posix file \"/System/Library/CoreServices/Diagnostics Reporter.app/Contents/Resources/AppIcon.icns\" buttons {\"OK\"} default button {\"OK\"})"
clickedButton=$( /usr/bin/osascript -e "$diskmsg" )
## Run additional commands #####
exit 0
