eventlog is a library for creating structured events from applications, and is the workhorse behind syslog-ng's own messages.

eventlog's Introduction

The EventLog library aims to be a replacement of the simple syslog() API
provided on UNIX systems. The major difference between EventLog and syslog
is that EventLog tries to add structure to messages.

Where you had a simple non-structrured string in syslog() you have a
combination of description and tag/value pairs.

EventLog provides an interface to build, format and output an event record.
The exact format and output method can be customized by the administrator
via a configuration file.

Installation
------------

Installing this library is quite straightforward as it does not depend on
anything but libc.

First grab your copy of the library. It is a tarball named
eventlog-x.x.x.x.tar.gz where x.x.x.x is the library revision.

tar xvfz eventlog-x.x.x.x.tar.gz
cd eventlog-x.x.x.x
./configure
make && make install

If you want to package the library or move the binaries to another system,
you can use the DESTDIR argument to 'make install' like this:

make DESTDIR=/tmp/staging install

which will use the /tmp/staging directory as root and copy all files beneath
as it were a real system.

Copyright

EventLog is distributed under the terms of a BSD style license, for details
see the file COPYING.

eventlog's Issues

Release of eventlog

Is eventlog still a dependency for syslog-ng? Is there any official (current) release of eventlog?

Maybe I'm wrong, but the highest version of eventlog is 0.2.13 which is in this repo, but there are no release from this. Is there any plan to release eventlog?

Provide a working release source tarball download

Currently there seems no way to get a release source tarball of eventlog as http://www.balabit.com/downloads/files/eventlog/0.2/eventlog_0.2.13.tar.gz redirects to oneidentity.com. It would be nice to have them added on Github as well like done for syslog-ng.

Can't build dynamic library on Cygwin

Unfortunetly I am unable to use the version of syslog-ng included with cygwin as it lacks SQL support so i'm having to build from source on it. But when I compile EventLog 0.2.12, downloaded from https://my.balabit.com/downloads/eventlog/0.2/eventlog_0.2.12.tar.gz on Cygwin x64/Windows Server 2016 Core, the dynamic libraries are never made, only static libraries. And syslog-ng's make will fail if there are not dynamic libraries for EventLog.

----------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-LLIBDIR' linker flag

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
