netwatch !!!

i want to implement netwatch script on my MT but i read whole forum and i cannot find where to put script where will be right place..
do i must put it in up/down script in /tool->netwatch or i must put it in /system->scripts and afterthat call that scripts from /tool->netwatch ?

something confuse me, in source script it says that can ping host in specific interval and etc and if i put it in /tool->netwatch, netwatch also ping specific host (i think one ping only on specific interval, which is very bad for realistic monitoring) and i dont know which of two of them (ping) is used for monitoring first. because logically, first action will be monitoring host itself by netwatch and then action will be taken with UP/DOWN script in /tool->netwatch not /system->scripts?

is that right or ?

You can either put the script directly into the up down events, or you can call a system script from there.
Netwatch does the pinging, there’s no need to ping from the script fired on the event.

ok,great fewi but is that ping from netwatch himeself i read it somewhere that is only one ping or im wrong?
in the scripts source ping is much more complex and reliable (in the situation of packet loss)

so your advice is to put in netwatch directly in UP/DOWN and that would be enough?

in that case, use Scheduler to run your script
