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"?
