syslog-ng 4.0 roadmap plus release policy changes

I've updated the syslog-ng OSE roadmap on the syslog-ng webpage to include information about the upcoming syslog-ng version:

http://www.balabit.com/network-security/syslog-ng/opensource-logging-system/roadmap/

Also, I'd like to bring the changed release/support policy to your attention, that you can read at the same location above. I'd like to introduce stable track and feature track releases, the first being supported for a long time, whereas feature track releases are only supported until the next feature/stable release is published. When a sufficient number of features were published via feature track releases, the last one becomes stable and the cycle continues. Note that feature releases are NOT development snapshots, they are releases just like the major versions previously, the only difference is that instead of a large feature list like with syslog-ng 3.0, only a smaller set of changes are included.

This makes it possible to publish features more often, always concentrating on a few of them at a time, instead of doing development for a long time and come out with a feature packed release. I hope to increase the pace of syslog-ng development with this change and also to cause less problem for users who prefer stability over features. Please read the details on the roadmap page.

I've also opened the syslog-ng 3.1 repository and pushed it to our git server. Right now there are no differences (except for the version number) between 3.0 and 3.1, I'm planning to integrate Marton's message tagging and patterndb changes as soon as possible (his git tree is here). Hopefully the 3.1 cycle will be quite short as most of the things on the roadmap are already implemented, although scattered around in various public and private trees.

With the opening of the 3.1 branch, I'm also obsoleting 2.0 (in the new support model two stable track versions are supported at any given time and we have 2.0, 2.1 and 3.0 right now), but that'll go in a separate post/announcement.

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 roadmap 2.1 & 2.2

We had a meeting on the syslog-ng roadmap today where we decided some important things, and I thought I'd use this channel to tell you about it. The Open Source Edition will see a 2.1 release incorporating all core changes currently in the Premium Edition and additionally the SQL destination driver. We are going to start development on the 2.2 PE features, but some of those will also be incorporated in the open source version: support for the latest work of IETF syslog protocols unique sequence numbering for messages support for parsing message contents Previously syslog-ng followed the odd/even version numbering to denote development/stable releases. I'm going to abandon this numbering now: the next syslog-ng OSE release is going to have a 2.1 version number and will basically come out with tested code changes only. The current feature set in PE were developed in a closed manner and I don't want to repeat this mistake. The features that were decided to be part of the Open

syslog-ng 3.0 and SNMP traps

Last time I've written about how syslog-ng is able to change message contents. I thought it'd be useful to give you a more practical example, instead of a generic description. It is quite common to convert SNMP traps to syslog messages. The easiest implementation is to run snmptrapd and have it create a log message based on the trap. There's a small issue though: snmptrapd uses the UNIX syslog() API, and as such it is not able to propagate the originating host of the SNMP trap to the hostname portion of the syslog message. This means that all traps are logged as messages coming from the host running snmptrapd, and the hostname information is part of the message payload. Of course it'd be much easier to process syslog messages, if this were not the case. A solution would be to patch snmptrapd to send complete syslog frames, but that would require changing snmptrapd source. The alternative is to use the new parse and rewrite features of syslog-ng 3.0. First, you need to f
