[Serusers] Monitoring

[Cesc]

Hi,

some asked me if i could share the script ... yes, i can ... but it is
in no way a nice script. It is done by me (mostly) ... but is done FOR
me, so you may need to change a few things to make it work ... sorry
:)

PS - there is more info on the README inside the attached tgz file
