I'm looking for reliable monitoring system for my webhosting business.

I've searched with google and found dozens of them....

Which one to choose?

Did anybody use www.serviceuptime.com?

Honestly, I wouldn't trust ANY third party service.

Go with either something in-house, or at the very least; reliable. Try www.paessler.com for their IPCheck software.

I do use serviceuptime and had no problems with them so far. didn't get any false alarms yet and sms alerts also rules. try it.

I dont use www.paessler.com but I have heard of it and have heard good reviews about it. Good luck in finding one that you like.

Thanks all!

So, I've finally chosen www.serviceuptime.com... Seems it is what I need. Their free accounts has almost no limitations... even SMS alerts is available!

www.siteuptime.com
www.alertra.com
www.websitepulse.com

Why don't you like awstats? It's provided by every host nowadays.

Hostracker is one of the best tools for that.

siteuptime.com is really a good tool.
