Flexnet License Monitoring With rrdtool
26 / 3
http://www.howtoforge.com/flexnet-license-monitoring-with-rr...
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, whether they are underutilized (so money is wasted) or are always fully utilized (so that you can suspect that sometimes people cannot 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 spend money. Why not build a simple system yourself, which shows the actual and past usage in an "MRTG style"?

25 / 6
http://www.howtoforge.com/postfix-monitoring-with-mailgraph-...
This article describes how you can monitor your Postfix mailserver with the tools Mailgraph and pflogsumm. Mailgraph creates daily, weekly, monthly, and yearly graphs of sent, received, bounced, and rejected emails and also of spam and viruses, if SpamAssassin and ClamAV are integrated into Postfix (e.g. using amavisd-new). These graphs can be accessed with a browser, whereas pflogsumm ("Postfix Log Entry Summarizer") can be used to send reports of Postfix activity per email.

Server Monitoring With munin And monit On Mandriva 2010.0
25 / 5
http://www.howtoforge.com/server-monitoring-with-munin-and-m...
In this article I will describe how you can monitor your Mandriva 2010.0 server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems, and a watchdog that ensures the availability of the monitored services.

Network Monitoring Appliance
26 / 3
http://www.howtoforge.com/network-monitoring-appliance
My ambition was to implement a small (better tiny) appliance for monitoring network health and network resources, short and longtime trends, running under VMware Server or VMware ESX. So I had an eye upon all components which are implemented on the system, to be as leightweight as possible. This was also the reason why no SQL DBMS based software was used. The appliance is based on Ubuntu Jeos LTS (8.04.3 at the time of this writing). Almost all used components are from the related repositories. This tutorial shows how the appliance was implemented.
