Things i have done

Welcome to my portfolio. Click the icons to the right to see more about the projects.

Please keep in mind that this, ofcourse, is just a small portion of what I have done. It is simply too much work to put every little tinkering up here.

Most of these things here were created on a "professional" basis. For the more hobby-like projects I'd like to point out the playground section.

Short description:

A php based monitoring system for 80 linux servers.

Long description:

This project was build to monitor 80 linux servers located at remote locations. Normally the company had to wait for errors to be reported before action could be taken. Because of a centralized monitoring system it was now possible to deliver preventive support. I.e. lost internet connections, frozen print queues or full disk drives.

Technical:

The system was build on a combination of php, shell scripts and the MRTG database (used to store and graphically display statistics).

A crontab was added on the remote servers that ran a shell script that collected various information and stored it in a comma seperated text file. This file was then emailed to a central server which used postfix' aliases to redirect the incoming mail to a shell script on that server. That script executed the neccesary commands to store the collected information in an MRTG database.

The MRTG database was then read by php scripts that displayed it to the support desk employee.
