PACKAGE : libumberlog
VERSION : 0.1.1
SUMMARY : First (public) stable release
DATE : 2012 April 2
HOMEPAGE :
http://algernon.github.com/libumberlog/
---------------------------------------------------------------
DESCRIPTION:
The libumberlog library is a a thin layer over the traditional
syslog() function that turns your legacy syslog messages into
structured logs, so that the message part becomes a JSON string (see
the example below), with a couple of extra fields added by default: a
high-precision timestamp, uid, gid, and pid, to name a few.
The library can be used as a system-wide LD_PRELOAD-ed library,
turning every syslog() message into the improved format, or it can be
LD_PRELOAD-ed on a case-by-case basis, or even linked to, in which
case it provides a few other functions, mentioned below.
EXAMPLE:
Mar 24 12:01:34 localhost sshd[12590]: @cee:{
"msg": "Accepted publickey for algernon from 127.0.0.1 port 55519 ssh2",
"pid": "12590", "facility": "auth", "priority": "info",
"program": "sshd", "uid": "0", "gid": "0",
"host": "hadhodrond", "timestamp": "2012-03-24T12:01:34.236987887+0100" }
FEATURES:
The library supports LD_PRELOAD (and has been used in such capacity on
production systems), turning legacy messages into something little bit
more structured, yet, backwards compatible.
It also introduces a few new functions, namely ul_format() and
ul_syslog(), that allow one to make use of structured logging even
better, by allowing them to include arbitrary key-value pairs in the
message.
