Sisolo is a simple solar logger, meant to run on small embedded devices, like routers. Currently it targets OpenWrt, uses Yasdi to interface with SMA inverters and Curl to store logs on an ftp server.
This is a conf based traffic logger, each conf log in/out traffic for:
* some definable hosts.
* in a definable device.
* which match a definable pcap filter.
All the logged data can be displayed(actually rrd graphed) via a web perl/cgi
