Simon 4.3.1Simon 4.3.1
Monitor websites and servers for changes or failures

Customer comments:

I've used Simon for about 6 or 7 years with considerable success to monitor many boxes and processes. It can be set up very granularly, or just is it up. Very reasonably priced - 5 min setup and learning curve - flexible - great forum, and VERY responsive developer.
John Gonder, Cisco Academy Director, Las Positas College
Simon is working really really well. It alerts us via emails to our cell phones and we usually know if something hangs before a client does. Thanks.
Scott Karch, Technology Director, Facility Wizards
I have to say this software is absolutely amazing, I love how custom it can be. Thanks for the great support!
Pete Sanders, Network Analyst, Fuse Technology Group
On the surface, Simon is a simple Mac utility which runs all the time, checks web pages, sends out notifications when things are not as they should be. Behind the scenes, Simon is a top-notch server monitoring system with bells and whistles, and each of them have bells and whistles.
Katherine MacKenzie, PixoBebo (read review)
Simon is full of nice touches and is a very polished package. The flexibility in setting up a variety of tests and customising the different notifications is simply amazing. And it is so easy to configure. The developer is also very helpful and responsive. This is by far the best software I have purchased this year (& maybe will be all year).
Charlie Garrison, Managing Director, Make-Tracks Secure Hosting
I've been using Dejal Simon 2 for over a month to track client sites that I host under a reseller service and was so impressed with this solution that I recently purchased a corporate-level license. I've found it to be an invaluable tool that includes a wide feature set and an innovative interface. I've communicated with the developer, David, on several occassions and was very impressed with the level of support he provides and his openness to user feedback. Highly recommended!

...I had to write to let you know how happy I am with your product. I currently manage 139 individual domains. Simon has been a god send. The previous version of Simon worked well. However, I have noticed a big jump in effeciency with monitoring over 130 domains at one time. You guys have a great product.

You now have a watchdog that lets you have a life again as a system administrator.
Robert Pritchett, macCompanion
Simon constantly monitors the content of critical pages and shows me the changes that have been made. Quality control is very important to me: usability, reliability, design, that's what people pay me for! In Simon I also find those qualities -- and this feels good to me. ... Simon adds another reliable and highly customizable layer of control and feedback! I also appreciate the fast response when contacting Dejal. The developer knows what he's talking about!
