Nordic Nagios Meet '08

I've spent the good part of last week in Stockholm at a gathering of Nagios users and developers. I was invited to give a talk on syslog-ng and security issues about collecting syslog data centrally as syslog-ng is often used hand-in-hand with Nagios.

This was my first time in Sweden and I can say that Swedish people are the most hospitable nation I met so far, and Stockholm is a very nice city. Also op5, the company organizing the event did their best to make us - the speakers - very welcome.

Thanks op5.

If you have a chance visit Stockholm I'd recommend to do so.

syslog-ng fun with performance

I like christmas for a number of reasons: in addition to the traditional "meet and have fun with your family", eat lots of delicious food and so on, I like it because this is the season of the year when I have some time to do whatever I feel like. This year I felt like doing some syslog-ng performance analysis. After reading Ulrich Deppert's series about stuff "What every programmer should know about memory" on LWN, I thought I'm more than prepared to improve syslog-ng performance. Before going any further, I'd recommend this reading to any programmer, it's a bit long but every second reading it is worth it. As you need to measure performance in order to improve it, I wrote a tool called "loggen". This program generates messages messages at a user-specifyable rate. Apart from the git repository you can get this tool from the latest syslog-ng snapshots. Loggen supports TCP, UDP and UNIX domain sockets, so really almost everything can be me...

syslog-ng OSE 2.1 released

I have just uploaded the first release in the syslog-ng Open Source Edition 2.1 branch to our website. It is currently only available in source format at this location: http://www.balabit.com/downloads/files/syslog-ng/sources/2.1/src This release synchronizes the core of syslog-ng to the latest PE version and adds the SQL destination driver. This is an alpha release and thus might be rough around the edges, but it basically only contains code already tested in the context of the Premium Edition. The SQL functionality requires a patched libdbi package, which is available at the same link. We're going to work on integrating all our libdbi related patches to the upstream package. If you want to know how the SQL logging works, please see the Administrator's Guide or our latest white paper Collecting syslog messages into an SQL database with syslog-ng. The latter describes the Premium Edition, but it applies to the Open Source one equally well.

syslog-ng 3.2 changes

I've just pushed a round of updates to the syslog-ng 3.2 repository, featuring some interesting stuff, such as: SQL reorganization: Patrick Hemmer sent in a patch to implement explicit transaction support instead of the previous auto-commit mode used by syslog-ng. I threw in some fixes and refactored the code somewhat. Configuration parser changes: the syntax errors produced by syslog-ng became much more user-friendly: not only the column is displayed, but also the erroneous line is printed and the error location is also highlighted. Additional plugin modules were created: afsql for the SQL destination, and afstreams for Solaris STREAMS devices. Creating a new plugin from core code takes about 15 minutes. I'm quite satisfied. With the addition of these two modules, it is now possible to use syslog-ng without any kind of runtime dependency except libc. The already existing afsocket module (providing tcp/udp sources & destinations) is compiled twice: once with and once withou...
