Netwatch

Hi

I need help to write a script that will send me an alert via Email if one of my hosts go down.
How can i do this via Netwatch. I have already entered the mail server details on the mikrotik.

Thanks in advance

simply add one line to netwatch to send an email.
Here is a script example how to send backup file, you can use it also for your needs.
