syslog-ng for filtering and execute external application
by Thomas Schmiedl 29 Apr '19

29 Apr '19

Hello, I use the mediaserver xupnpd2 (https://github.com/clark15b/xupnpd2) on the router to show HLS streams on the TV. Unfortunately, the software is no longer maintained by the original developer (I'm not a developer myself). The HLS processing would have to be revised. My idea is to start a ffmpeg and a local web server on the router, if I want to display the stream (the script xupnpd.lua will be executed, which starts ffmpeg etc.). Unfortunately there is not such a script when terminating the stream (exit ffmpeg etc.). xupnpd2 uses a log where you can track the start as well as the ending of the stream. Since the router has only a small amount of internal memory to write and analyze a logfile, I have the question, if I could use syslog-ng to filter the start and stop of the stream and execute an action "ffmpeg stop" and "delete video segments". I have very little Linux knowledge, maybe you can help me. Here is the excerpt from the xupnpd2 log (Loglevel 8). When starting the stream: run child, pid = 1715 using handler 'hls' for '... URL ...' When stopping the stream: exit child, pid = 1715 Best regards, Thomas Schmiedl

how to insert a word before forwarding to another remote host
by Lin, Victor 25 Apr '19

25 Apr '19

Dear all, Could anyone let me know how can Insert a label into a syslog message? I received Cisco syslog from port514, Arista 5214, Airwave 5514, then my syslog forwarding these into one remote host with port 5714 ( they don't want separate port for each vendor) , so I will need to insert "Cisco" or "Arista" or "Airwave" before forwarding Thank you very much for your direction!

startup and network sources
by Evan Rempel 18 Apr '19

18 Apr '19

I've been looking at an interesting scenario on Redhat 7 (systemd) where syslog-ng fails to start because it can not resolve a network source name. This happens because the network has not started. Systemd attempts to restart syslog-ng a few times and then decides that it is restarting syslog-ng too quickly and gives up on it. 2019-04-17T05:13:30.009 daemon.warning systemd[1]: start request repeated too quickly for syslog-ng.service 2019-04-17T05:13:30.010 daemon.err systemd[1]: Failed to start System Logger Daemon. 2019-04-17T05:13:30.010 daemon.notice systemd[1]: Unit syslog-ng.service entered failed state. 2019-04-17T05:13:30.010 daemon.warning systemd[1]: syslog-ng.service failed. My first reaction was to add the "Wants=network-online.target" to the service definition to make syslog-ng start after the network has started, but that would mean that if I boot up without a network that syslog-ng would never start, and that seems incorrect to me. Is there a way to to configure a network source to be optional and continue to retry binding to it after startup? How do others handle this issue? -- Evan

Permissions Issues
by Faine, Mark R. (MSFC-IS40)[NICS] 16 Apr '19

syslog-ng 3.18.1 RHEL 6.10 Can someone please help me understand what I'm doing wrong? I thought that when I set the following on a destination: create_dirs(yes); dir-owner(myuser); dir-group(myuser); group(myuser); owner(myuser); perm(0640); that files and directories would be created with those permissions, however, I'm seeing something strange. It seems that syslog-ng still wants to create and write to files with root.root. Also, and this is even more unexpected. If I change the permissions on the directories before starting syslog-ng, it fails to write to the directories that are not root.root. Am I missing something? Thanks, -Mark

Insider 2019-04: Tetris; Docker; Podman; python-fetcher
by Czanik, Péter 10 Apr '19

10 Apr '19

Dear syslog-ng users, This is the 74th issue of syslog-ng Insider, a monthly newsletter that brings you news related to syslog-ng. NEWS Tetris destination ------------------ In this blog post we show you a fun way of using the Python destination of syslog-ng. We will write a Tetris destination. We will use the built-in Tetris implementation of Emacs. The syslog-ng Python destination will connect to an Emacs server. The log messages will be turned into Tetris commands inside Emacs. Using an stdin source, users can interactively feed syslog-ng with messages that will control the Tetris in the end. https://www.syslog-ng.com/community/b/blog/posts/tetris-destination A simplified guide to logging Docker to Elasticsearch in 2019 using syslog-ng ----------------------------------- This simplified guide shows you how to send logs of containers into Elasticsearch. Although there are several tutorials on logging Docker to Elasticsearch, this one is entirely different, as it uses syslog-ng. You can also visualize your Docker logs on a nice dashboard in Kibana. https://balagetech.com/simplified-logging-docker-elasticsearch-syslog-ng/ Replacing Docker with Podman in the syslog-ng build container ------------------------------------------------------------- The syslog-ng source code includes a container-based build system. You can use this build system to generate source tarballs (the official syslog-ng release tarball is also generated this way) and to build packages for RHEL 7 as well as different Debian and Ubuntu releases. Although it was originally built around Docker, with the general availability of RHEL 8 is drawing near, I wanted to know how difficult it is to replace Docker with Podman in the syslog-ng build system. Originally I tested this replacement on Fedora Silverblue (Silverblue), then a week later on RHEL 8 Beta. While the syslog-ng build scripts do not support these distributions (yet), the point was to check Podman as a Docker replacement. https://www.syslog-ng.com/community/b/blog/posts/replacing-docker-with-podm… The syslog-ng python-fetcher(): collecting load average data ------------------------------------------------------------ Using python-fetcher() simplifies developing a source driver for syslog-ng even further. You do not have to implement your own event loop, since syslog-ng does it for you. You only need to focus on what information you need and how you (or your code) can fetch it. In this blog I will show you two examples. The first one is a dead end: it is a project that looked simple at first but turned out to be problematic later on. The second one is simple but still manages to illustrate most features of the python-fetcher. https://www.syslog-ng.com/community/b/blog/posts/the-syslog-ng-python-fetch… CONFERENCES * LOADays (https://loadays.org/) syslog-ng featured in my sudo talk * Red Hat Summit (https://www.redhat.com/en/summit/2019) One Identity booth WEBINARS Upcoming: * Bridge the gap between cloud and on-premises: https://www.syslog-ng.com/event/bridge-the-gap-between-cloud-and-onpremises… You can watch our past webinars: * Got a hungry Splunk?

Re: [syslog-ng] syslog-ng Digest, Vol 168, Issue 11
by Aguilu, Miguel 10 Apr '19

10 Apr '19

If it is a simple typo I do not see it. But I did remove all sources with the exception of the upd on all filters. So, it is writing the udp traffic to the log. But getting errors: - You are using the pipe() driver, underlying file is not a FIFO, it should be used by file(); filename='/opt/log/nco' - Apr 9 19:18:01 eorcrp-dsc-ncsl1-new-ms syslog-ng[15695]: Error opening file for writing; filename='/opt/log/nco', error='Invalid argument (22)' Regard Essentially I can write to a log but not a pipe even when create the file as a pipe or let syslog-ng create it - eventually after the creation will start companying it can't write to it. Not sure if I am missing something the pipe configuration (don’t think so) or there is a bug in this version 3.19/3.14/3.1. Yes I am on my 3rd version to see if a see anything different.

tcpdump shows device sending syslog from UDP

Hello Fabien, I was running tcpdump on my syslog-ng server, and able to see the package from 1.2.3.4 but my local logfile for UDP 514 didn't show any syslog from 1.2.3.4.
