Graphs are fun, especially when its stuff thats relevant to me and things that have happened over time. A long time ago I posted about the program I made to generate a graph of my AIM usage. That graph recently passed 750,000 lines! Another recent milestone was passing the 30,000 listened song number on my last.fm profile. Thats a lot of lines and songs. Another favorite graph of mine is the performance data for my server graphed with MRTG. They work great when you configure them properly, but two mistakes have burned me a little bit. Each time, I used a configuration script that someone else had written that had limits hardcoded into it. This lead to the mailserver throughput being limited to 25 messages until May of this year when I realized the problem, and the database throughput being limited to 2000 queries a second until late last month when I noticed. After fixing the problems, the graphs changed substantially. Emails approach 250 in a five minute period every now and then, and database queries approach 10,000 for 5 minutes. Because of the change to the db graphs, it now lines up much more accurately with the CPU usage and network traffic graphs. (The primary load on all 3 of those is the database driven dynamic content load of this site and Faster Mustache.) The last graph of interest for today is the project activity statistics for Gallery. As the Gallery project manager, I try to stay aware of everything that is going on and the statistics that SourceForge provide are important metrics. Browse around and check them out, they're pretty interesting, but I stumbled across one thing that makes a lot of sense afterwards but was a bit of a surprise: Closing tracker items (bugs, tasks, feature requests, etc) that were recently created increases the average age for open tracker items. I was trying to get the average age down by closing things that were no longer relevant, but because the density of items is a fairly sharp peak of current items with a long tail, closing the same percentage of recently opened items and old items increases the average age. Ah well. I just need to get people to take care of all of the really old open things..
