PHP Server Monitoring

So with the company I need a better way to monitor all of the servers/domain names that we run. I need something that can run automatically in cron but display graphs of performance. You see there is a full spectrum between online and offline. Often you can see signs of a server about to go down by graphing its performance. Also since this is on the server I can go a step further to do some process monitoring. I would love to get a display with load of the server throughout the day. Then email me when load is approaching critical. I can’t really find anything out there right now so I’m probably going to hand code something.
