if you want a bit more heart beat information like load, free memory, temperature, service availablity, connection status etc etc you may consider using the free zabbix. I am using it and I am quite happy - tho it requires some linux experience to set it up
it supports a ton of sensors plus own triggers, error notification by mail and also shows nice graphs for people which prefer a graph over numbers :)

Following on mfeldheim's response -- there are a number of good tools out there to facilitate logging/displaying/graphing load averages etc. They generally vary by the complexity and versatility -- ideally, chose one that isn't too much of a pain to get going, and which provides decent flexibility once configured. Some options:
Munin [munin.projects.linpro.no] -- very versatile. Scout [scoutapp.com] -- very simple to get started with and configure. Nagios [nagios.org] -- somewhat intimidating in its breadth, but very flexible.
All these use an open-source plugin model to monitor a variety of stats. My guess is that once you've got load averages logging working, there are other metrics you're going to want to see alongside it, like disk I/O CPU utilization.
