openwrt_logger.py

This script is supposed to be run by cron every 5 minutes or so. It looks for new lines in log file and sends them to remote server.

OpenWRT must have remote logging enabled (UDP; IP of host this script is launched on; port 514)

/etc/rsyslog.conf contains following (assuming 192.168.1.1 is the router IP):

$ModLoad imudp  
$UDPServerRun 514  
:fromhost-ip, isequal, "192.168.1.1" /var/log/openwrt.log  
& ~

Also comment out the following line:

$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat

Cron line example:

* * * * *  /home/user/homekit/src/openwrt_logger.py --access-point 1 --file /var/wrtlogfs/openwrt-5.log  >/dev/null

/var/wrtlogfs is recommended to be tmpfs, to avoid writes on mmc card, in case you use arm sbcs as I do.
