I am using my old WL500gp as router and to collect data from my arduino sensors, running script which collescts data over serial line, parses it and save it in rrd database and online (cosm.com). I noticed strange disk activity every 5 seconds, trying to turn off screen session logging, increase data storage interval, and it all stays the same. Disk monitoring tools like atop are not functioning properly to identify specific process responsible for disk writes because support for it is not compiled into kernel.
Do you know any good method/tools for this?
