I'm looking for a server uptime monitoring service that will check my servers every now and then and give me a notice when things look bad. It would be great if it could say grab my main page every half/quarter hour and give me a notice when the server seems to be going under -- usually it takes a while until I stumble upon and notice that it's not responding :-).
Does anyone have a service that they use and can recommend? It doesn't have to be free, but I don't want to spend a fortune either :-).

I use them both. They are pretty much right on the money, I get an email within minutes if the site I am testing (representing the server for me) is down and again when it's back up. One of them tests every 15 minutes , the other one tests every 30 minutes.
They each test from several spots aroudn the world. it may be that the server is up but the network is down, or parts of the network are down.
At least one of those I mentioned can send a text message to a cell phone. I'm not doing that but I could, because they send daily, weekly and monthly summary emails too and I don't want to get flooded with text messages (they cost me $0.20 each) . I check my email often enough.

You can just set it up yourself if you have access to another server and the technical expertise. Otherwise, your ISP may offer it (for instance, The Planet does). The advantage of getting it from the ISP is that you can usually contract for them to fix the problem according to your escalation procedure, which means you can take vacations and the like without worrying.
Although you can't really monitor a server from the same server, there are limited things you can do. You can make a shell script set up as a cron job to watch the server load, swap space, the number of open connections, the MySQL load as percentage of CPU, etc., and take action (such as issuing a restart command) when the values go beyond some parameters (but before the server becomes completely unusable).
