If you buy a business or enterprise licence with Simple-Help you get remote management and monitoring.

Still rough around the edges and you need to be comfortable writing scripts as there is no base library to use, but the functionality is there. The missing part is the reporting. I have only been using Simple-Help use before Christmas so I'm still learning but some of the scripts\alerts I have in place are:
1. If free disk space falls below 10% run my disk clean up script
2. At 6pm on a Wednesday run Windows Update on Clients PCs and log the results (ABC-Update Script)
3. Run my Weekly & Monthly maintenance scripts automatically
4. Email me if a Server goes offline and when it goes back online
I used solarwinds for a number of years on my just my customer's servers that cost £65 per month. (£780 per year) The simple-help licence cost £330 and I'm running it on 300 plus clients so far, solarwind would cost £614 per month for that many clients. I'm happy with my choice, it doesn't have all the features of solarwinds, but has the ones I used the most for a fraction of the cost.
