Below is a snapshot of the 48 hour running window of graphs generated by the enhanced tellerstats shell scripts. This particular snapshot was chosen to demonstrate a small experiment. Note the huge spikes in the system load average plot. They were generated with a script that compiles the Linux 2.6.7 kernel in a loop, with the commands make -j3 MAKE='make =j3' clean;\ make -j3 MAKE='make =j3' bzlilo;\ make -j3 MAKE='make =j3' modules The effect was to keep the load average above 8 for more than 30 minutes. The effects (or lack of them) on system voltages and temperatures is visible in the resulting graphs. (A new graph, generated October 3rd, and unrelated to the others, has been added. The graph shows 5 inside and 3 outside temperature probes and data generated via a Crystalfontz CFA-633 device.) |
