System Monitoring With sar And ksar sar is one of the old and famous commandline utilities, which is often overlooked. It provides a wealth of information when you have kind of performance bottlenecks. By itself it only provides lengthy columns of numerical data, kind of hard to interpret. sar exists on most Linux distributions, for example Ubuntu, Debian, CentOS, Gentoo, and is also available on Solaris, AIX, and other commercial Unices. ksar, on the other hand, is a Java based front end for sar's numerical data. It produces friendly graphs which could be exported to .pdf and some other formats.

Flexnet License Monitoring With rrdtool Some of you may know the commercial Flexnet Licencing Application (©Macrovision). It's a client-server based solution for managing the usage of socalled Flexnet-enabled applications. You can hold licenses of more than one product on one license-server. As you typically have to buy licenses and licenses can be expensive it would be nice to have a monitoring solution, to see the utilization of the precious licenses, wether they are underutilized (so money is wasted) or are always fully utilized (so that you can suspect that sometimes people can not do their work, or only delayed) which is also a waste of resources. As far as I know there are commercial applications for performing such reports, but again you have to spent money. Why not build a simple system yourself, which shows the actual and past usage in an "MRTG style"?
