syslog-ng Open Source Edition 3.3.1 released
I’m proud to announce that syslog-ng 3.3.1 has been released.
It is an important release in a number of ways:
- syslog-ng architecture was completely revamped to scale properly in
today’s multi-core environments. I’ve seen it process 800000 messages /
second in some scenarios. - following the licensing change in 3.2, it incorporates contributions
(code, testing & feedback) from 54 individuals.
In total, the development of 3.3 took about a year, producing 580 patches and the following diffstat:
294 files changed, 20314 insertions(+), 7624 deletions(-)
That compared to the total number of lines in the git repository (81804 lines) is a significant change over 3.2
See the syslog-ng ohloh page for more statistics:

For the list of features and changes, please see the NEWS entry.
You can download the source code from:

A number of distributions already carry 3.3.1 packages thanks for our faithful package maintainers.
You can also get the source code from git, at
Happy logging.

Back to this again!!
So the filter in your other post dated “Nov-23-2008″ – is it still working fine with the new versions?
No snmp source was implemented so far. The premium editiom has an SNMP destination, that converts syslog to snmp, but that’s the reverse thing.
It’d be possible to do, but hasn’t been done yet. If someone would contribute it I’d definitely merge it though.
Hi there;
May I ask has ever the snmptrapd filter integrated into syslog-ng (referring to your Nov-23-2008 archive here) or still we have to do it manually?
Which version then I have to use for this?
Best Regards;
Szia Bazsi!
Alkalmanként rátok szoktam nézni, hogy éppen mekkorára nőttök, hol jártok a sikerek útján.
Mindíg sikerül meglepődnöm, és mindíg valamiféle büszkeség fog el engem is! Továbbra is szurkolok nektek, és veletek együtt örülök a sikereknek!
Gratulálok az új fejlezstőközponthoz és a Superbrands díjhoz is. Nagyok vagytok!
