I purchased a new computer recently to replace several of my old ones. Two computers in particular were responsible for retrieving graph data and plotting graph data respectively. The new system has a slightly different Munin configuration because I switched from Debian to Ubuntu. So the graph colors will be different. Also some of the long term graphs may be blank for up to a day until they get regenerated but no data was lost.
This new system will open up new possibilities for doing more processor and memory intensive analysis of the crawler data. Stay tuned for cool new features.
