Quick monitoring question

ghughes5669 · 06-03-2014, 12:25 PM

Greetings, all!

I'm looking for a host-based network heartbeat tool. This would live on a host (virtual or physical) and ping an address outside my network (Google's DNS servers, probably). If the ping doesn't respond within a set parameter, the tool send an email out to alert that the host has probably lost contact with the outside internet.

Is there such a monitor out there?

Thanks!

You do realize what you just asked for, don't you? Did you read the question you posted??

How, exactly, is something going to send an email, when the Internet is down or can't be connected to???? If you mean send an INTERNAL email on your own private network, then a monitor isn't what you need..just a simple bash script to ping Google every now and then, and send an email if it doesn't get a response. There are many examples of this:

A full-blown monitoring tool like Nagios or Zabbix can also be configured for this (and many OTHER tasks), but may be overkill.

Yes. You can also install a 3g/4g card, or a POTS connection to your router/FW to do out of band communication like this, when your wired DC connection goes down. You will then utilize the programs Tb0ne pointed out.
