how to monitor Server A ping to Server B

[exfish]

Sometimes, I need monitor if server A can ping to server B, or check the server B tcp port status from server A.

Does anyone have a well method?

ping -q -c1 host.example.com >/dev/null && echo 1 || echo 0

This will output "1" if the ping succeeds, "0" otherwise.

However, it relies on one single ICMP echo request.
You could put it into a UserParameter on Server A:

UserParameter=user.pingto[*],ping -q -c1 $1 >/dev/null && echo 1 || echo 0

and create an Item with key: user.pingto[<IP.Addr.of ServerB>]
that will return service state Up(1) or Down(0)

Thank you so much, it's a good way.

For windows ...

I stumbled onto this thread because I wanted to do the same thing for Windows, BUT of course, it's a bit different.

For anyone else that needs it, here is how I did it for Windows hosts:

UserParameter=pingto[*],ping -n 1 $1 > NUL && echo 1 || echo 0
