Free Monitoring Software

I have 3 servers in my office that i would like to be able to monitor via ping.  All i want to do is monitor and alert if they go down.  I don't need anything else.

Since these devices are inside my network pingdom is not a viable solution.

Any suggestions?

PRTG is what you are looking for.  Easy, reliable, and I have used it for several clients.  Also it will be free for you becuase you only have three devices.

If you want to get fancy go for Spiceworks.  ANother great free tool that is much more in-depth.

Firstly, Zenoss and Nagios are truly great but they all do require some configuring.

To monitor 3 systems with ping you might just want to script something. Bear in mind though that a server that may respond to ping doesnt actually mean the service is available, it just means it's up and responding to icmp. if this is all you want then a script that just sends a single ping to each server every x minutes and emails someone if there is not a successfull connection might do the job for you. If you want to make sure services etc are running then you'll need to look a bit deeper.

Are you going to monitor them from a separate system, it might be best to!
The options I originally linked are more geared towards SNMP monitoring when you was ICMP monitoring. Here are suggestions for free ICMP tools with email notifications.
