The 127.0.0.1 is loopback (local-only network) => you cannot access it from 
other network hosts.

You have two options if you want to test it:
1.) reconfigure MySQL to listen on any network interface
2.) or install monit on that machine and test it via 127.0.0.1

But first - i think you should read some linux administration and network 
basics, as it's dangerous to try monitoring something when you don't understand 
how it works.
