syslog parser modified in git head
by Scheidler, Balázs 10 Aug '17

10 Aug '17

Hi, The pull request #1617 has just been merged, which adds a slight modification to the way we parse RFC3164 syslog messages, by adding support for IPV6 addresses in the host field. Since changing that parser always makes me nervous (lot's of heuristics to support a number of different logging formats), it would be great if any of you having "strange" logging formats (appliances in general, Cisco, F5, Juniper, Huawei, etc) devices could validate that we didn't break anything major. The change is pretty focused, e.g. we accept an IPV6 address as a hostname if it matches the general format of IPv6 addresses. But the interpretation of the ':' character has slightly changed. This could cause hostnames and program names to be parsed incorrectly. Any feedback would be appreciated. -- Bazsi

I don't recall people mentioning any of the other modules recently.

Insider 2017-08: 3.11 released; wildcard-file; docker; SCL; RMLL/LSM;
by Czanik, Péter 02 Aug '17

02 Aug '17

Dear syslog-ng users, This is the 60th issue of syslog-ng Insider, a monthly newsletter that brings you syslog-ng-related news. NEWS syslog-ng 3.11 released ----------------------- The latest version of syslog-ng, 3.11 is now available. The most important new feature is the GeoIP2 parser which builds on libmaxminddb providing both better performance and more detailed geographical information about IP addresses. AMQP destination now supports SSL. There are many more smaller features and bug fixes. For a complete list check the release announcement: https://github.com/balabit/syslog-ng/releases/tag/syslog-ng-3.11.1 Reading multiple files: wildcard file source ------------------------------- Starting with version 3.10, syslog-ng can collect messages from multiple text files. You do not have to specify file names one by one, just use a wildcard to select which files to read. This is especially useful when you do not know the file names by the time syslog-ng is started. This is often the case with web servers with multiple virtual hosts. https://www.balabit.com/blog/reading-multiple-files-wildcard-file-source-sy… Collecting Docker infrastructure logs ------------------------------------- Why use syslog-ng for collecting Docker logs? Docker already provides many drivers for logging, even for central log collection. On the other hand remote logging drivers arrive with a minimalist feature set and you are not able to use the “docker logs” command any more. To have the best of both worlds, you can use journald logging driver in Docker and use syslog-ng to read Docker logs from journald and forward log messages to your central log server or other destinations. You can even run syslog-ng itself in a Docker container, so you can use it on dedicated Docker host environments as well where it is not possible to install additional applications. https://www.balabit.com/blog/collecting-docker-infrastructure-logs-using-sy… The power of SCL ---------------- The syslog-ng configuration library (SCL) can help you to configure syslog-ng a lot more easily. These configuration snippets can hide away the complexity of collecting, parsing or storing log messages. >From this blog you can learn how to parse web server logs and store the results at a Logging as a Service (LaaS) provider in a structured form. You will use SCL both for message parsing and the LaaS destination, and also utilize the wildcard-file() source introduced in syslog-ng 3.10. https://www.balabit.com/blog/parsed-web-server-logs-cloud-syslog-ng-scl/ RMLL / Libre Software Meeting 2017 ---------------------------------- This year I participated again in the security track of the largest French open source conference, Libre Software Meeting (RMLL). “Participated” as I did not only give a talk on syslog-ng there, but also sat in to most of the presentations and had very good discussions both with visitors and fellow speakers. The organizers brought together talks from diverse IT security related fields, a very good opportunity for cross-pollination of ideas. https://www.balabit.com/blog/czp-rmll-libre-software-meeting-2017/ NEW RELEASES syslog-ng OSE 3.11.1: https://github.com/balabit/syslog-ng/releases/tag/syslog-ng-3.11.1 Your feedback and news, or tips about the next issue are welcome at documentation(a)balabit.com.

eStreamer src Integration
by Scot 01 Aug '17

01 Aug '17

Has anyone looked at sending Cisco eStreamer events to syslog-ng ? We have a couple Cisco Firepower management centers and I would rather use syslog-ng over sending directly to splunk so that we may use other integrations like elastic and our NMS. I have the eStreamer SDK on my syslog-ng server and wondered if anyone else has worked on this. Search of the user archive says no. Thanks Scot

syslog-ng poll: geographical information
by Czanik, Péter 01 Aug '17

01 Aug '17

Hi, One of the major features of the upcoming syslog-ng 3.11 will be a complete rewrite of GeoIP support. So this time I ask you in the poll if you use syslog-ng to look up geographical information for IP addresses: https://twitter.com/PCzanik/status/891985964788330497 If you use GeoIP, please include your use case in the comments or answer this e-mail. You can e-mail me directly, if for some reason you don't want to share it with the rest of the world. Please re-tweet the above tweet to reach as many syslog-ng users as possible!

by Harish Shetty 28 Jul '17

28 Jul '17

Hi I am using "syslog-ng-3.9.1-1.el6.x86_64" . Few messages are not getting forwarded to destination (Monitoring hosts). But messages are receiving in syslog-ng server from the client. As a tuning parameter I am using log_fifo_size (20000); flush_lines (0); time_reopen (10); For source s_tcp , source s_udp and source s_net so_rcvbuf(8388608) max-connections(200) log-iw-size(20000) Could you please let me know , how we can avoid the messages are not getting forwarded ti destination. Regards Harish Shetty
