penlog server_ip server_port [my_ip]
Penlog reads webserver log entries from stdin and sends them using UDP to penlogd. It is intended for Apache's "reliable piped logs". To use penlog from Apache, add a command like this to the web server's httpd.conf:
CustomLog "|/usr/local/bin/penlog somehost 10000" common
The optional third argument is used if the server has several addresses. Penlogd uses the source address to identify the server, and it must be identical to the address configured in the command line to Pen.
