Script Netwach send SMS

Hi,

I read mikrotik documentation and on Mikrotik wiki for netwach script and I don’t find script for monitoring ISP.

In mikrotik exists Netwach but I don’t set up the number of ping. It is just ONE ping and timeout settings.

I want to send 1 SMS if ISP is down and 1 SMS is ISP is up.

Can anybody know ?

Regards,
