mlogger

A simple utility that logs different sources to syslog

It is based on bsdutils logger, which is shipped with many linux distros, Ubuntu being one.

It has been patched for:

• Log lines greater than 1k. Currently set to 64k. The limit can be raised even further by changing the MAX_LINE constant. You may also have to patch syslog.h for your kernel, this was not required on Ubuntu 12.04
• Indented line continuation. If enabled any line that begins with a tab or a space following a line that did was not indented will be added to the previous line(s). There is a configurable timeout to keep the detection delay to a minimum. A few milliseconds seems to work well here
• When logging to a UDP server (-n/--server), the size limit is still 400 characters. This limitation is inherit in UDP.
• When logging to a Unix socket (-u/--socket), the size limit is also limited by the kernel maximum size which is commonly around 120KB ( see /proc/sys/net/core/wmem_default ).
