Under a shingled roof / Soekris NET-4801 / FreeBSD-5.3release
Loopstats plot for a Garmin GPS-18LVC connected to a Soekris NET-4801 running FreeBSD-5.3release. The GPS was mounted approximately 12" under a shingled roof and the 4801 was sitting on a fibreglass batt, with the case cover removed, in an unheated attic crawlspace. The GPS was connnected to, and powered from, the 4801's internal serial port header. This plot is for January 1st, 2007 and was generated directly from the loopstats file instead of from periodic polls with a tool such as MRTG.
The peer summary (generated with peersum.awk) for this period is:
