SturdySystems provides system monitoring software for the enterprise and the individual. Our aim is to enable users to maintain and monitor their systems and to understand the workload and capacity from one simple console.
Radar Systems Monitor is now free for home and commercial use and is available for Windows NT, 2000, 2003, XP Pro, AIX, Solaris and Linux. Radar Systems Monitor provides 24 hours systems monitoring, logging, graphing and alerting and is designed to be very easy to customise.

Problem Fixing
Radar Systems Monitor can be incredibly useful for post problem cause determination, for example, if a problem occurred you could run
- Windows NT, Windows 2000, Window XP - The Windows Performance Monitor (perfmon)
- UNIX - vmstat, iostat, sar, netstat, lsps, entstat, tokstat, df, lsvg, lspv, mpstat, nfsstat, ps, svmon, vmtune
This will only tell you the values now. When a problem occurs, you want to know what happened up to this point. Was the machine busy, did the filesystems fill up, was the network connection available? If a filesystem is at 100% full, did it gradually increase (naturally growing data and log files) or was it a sudden increase (core dump or a user transferring files).
Using the watch window or Radar Systems Monitor, you can select multiple parameters (such as CPU activity, Paging) and go back to any point in time seeing all the values at that point.
Proactive monitoring
With Radar Systems Monitor, you can set thresholds to detect problems before they occur. You can send an email or run a script when filesystems free space falls below a threshold, paging space runs low, processes stop or print queues stop. Getting early notification can give the administrators time to fix the problem before it is even noticed by the users.
Saving Money
Radar Systems Monitor can save you money by identifying overloaded or under-utilised servers.
Here are some examples.
Q. Application x runs takes 3 hours to run overnight and is getting longer - What is going wrong? Should I upgrade the server?
A. Radar Systems Monitor can tell you what resources are being used overnight. Maybe you can rearrange your disks, prevent two CPU hogs running at the same time, or maybe it just needs a little more memory. Radar Systems Monitor can identify the problem resource at any point of the day and even alert you when thresholds are reached.
Q. I'm going to double my number of users on server x. Do I need to upgrade?
A. Radar Systems Monitor can show you how much of the CPU and Network is being used, how busy the disks are and whether the system is paging much (a possible sign of a shortage of memory). It may be obvious that the machine is considerably under-utilised and therefore could easily cope with the extra demand.
Q. I have a new application, where can I put it?
A. Radar Systems Monitor can show you which machines are busy and which are not. Therefore, you can decide which is the best machine to place it on without risking overloading and performance degradation. You can view 24 hours 7 days a week, to see if you have unknown overnight workloads.
