So, this year I have been spending most of my time digging in Network Management Systems both open and closed source. Think on Net-SNMP, SNMPTT, NAGIOS, CENTREON and you will get an idea. I promise i'll post more about this because is such an interesting topic.
Lately I have been with free time so I went back to Pentaho and discovered huge advances in the community ecosystem. Specially Pedro with CDF and Tom with Pat (erm now called Haiku).
As my boss wanted to show the quality status of our customers in a map, what I did was to use CDF with openlayers and open street maps. With some adjustments to the CDF's js libraries (the marker layer) I changed the presentation to render a circle with a color scale and whose size depends on the number of clients in the xy position. Here is the result:
Isn't open source software nice? :-)
