Below an example that you may customize to you own way... (let call it 
'mcfu.rc' )
--------8<-----------------------------------------------------------------
#!/bin/bash
### mcfu.rc : monit config file update
for i  in `cat /proc/mounts | cut -d ' ' -f 1 | grep -v none | tr "\n" " "`  ; 
do
        echo "### Checking $i"
        echo "check filesystem "`basename $i`" with path $i "
        echo "      if space usage > 80 % then alert "
        echo "" ;
done
--------8<------------------------------------------------------------------

In your generic monit file, something like  :

--------8<-----------------------------------------------------------------
check file mounts path /proc/mounts
     if changed sha1 checksum
        then exec "/usr/local/bin/mcfu.rc > /etc/monit/includes/checkspace.monit && 
/etc/init.d/monit restart"

include /etc/monit/includes/checkspace.monit
--------8<-----------------------------------------------------------------
