I recently had reason to collect metrics on a Linux server that was to be posted to an analysis service. My requirements were to collect minimum, maximum and average measurements of several key metrics. Shouldn’t be too difficult in this day and age, right?
OpenWRT is a project that has amazed me on multiple occasions. It’s an open source Linux-based Internet router firmware project, compatible with large numbers of off-the-shelf home and SoHo Internet broadband routers. Re-flash a compatible router with the OpenWRT firmware, and suddenly your router can do far, far more than than simple home broadband and wifi routing.
