rpmbuild on centos6
by Hajdu Tamás Márk 23 Nov '11

23 Nov '11

Hi everyone! I wanted to build rpm-s from syslog-ng (and maintain it in the future). I've using eventlog_0.2.12 (from source) which builds with some fiddling, but syslog-ng_3.3.3 (also from source) won't build. [rpmbuilder@svn ~]$ rpmbuild -ta rpmbuild/SOURCES/syslog-ng_3.3.3.tar.gz error: File /home/fathom/rpmbuild/SOURCES/ivykis-0.21.tar.gz: No such file or directory I have not found anything like ivykis in the .spec file, but I have downloaded it: [rpmbuilder@svn ~]$ rpmbuild -ta rpmbuild/SOURCES/syslog-ng_3.3.3.tar.gz error: line 135: second %prep Somehow it makes one spec file from the syslog-ng spec and the ivykis spec file... I tried to other way as well. Building it from the spec file cries for dependencies, including libevtlog and libnet-devel. The first is ok, but I do not really want to install that on the rpm building system, but the second one is totally missing from centos6. Has anyone some clues about this? It would be a pain in the ass to manually install/update everywhere. Hajdu Tamás Márk

Query regarding syslog-ng.conf and creation of logging files
by Ankit Mahawar 23 Nov '11

23 Nov '11

Hi, Please help regarding doubts of syslog-ng.conf file 1 . The destination files specified in syslog-ng.conf is created by syslog-ng ?? 2. If they are created by syslog-ng then , are they created only when the log gets filtered for that destination file 3 . Does this happen in syslog as well,because I think in syslog the file gets created even before logging into the file I am new to syslog utilities and it is just my assumption that the files might be created using the conf file ,because when I killed syslog daemon and restarted it ,the file I removed got created again but not in the case of syslog-ng. Please help regarding this issue ..

Cisco IOS message format
by Wells, James 22 Nov '11

22 Nov '11

Hi All, I am struggling to get syslog-ng to output the correct format for Cisco IOS devices. I am using syslog-ng to forward message to a NMS system. The issue I see is syslog-ng upon forwarding adds more data to the message as I am assuming it does not understand the Cisco IOS syslog format. Version of syslog-ng: Name : syslog-ng Relocations: (not relocatable) Version : 2.1.4 Vendor: Fedora Project Release : 9.el5 Build Date: Mon 16 May 2011 15:09:47 BST Install Date: Fri 21 Oct 2011 12:26:04 BST Build Host: x86-01.phx2.fedoraproject.org Group : System Environment/Daemons Source RPM: syslog-ng-2.1.4-9.el5.src.rpm Cisco IOS statements: service timestamps log datetime msec localtime show-timezone logging trap notifications logging facility local6 Syslog format in the local file: Nov 10 10:18:44.102 UTC: %SYS-5-CONFIG_I: Configured from console by testuser on vty0 (1.2.3.4) Syslog-ng conf file: options { sync(0); time_reopen(10); log_fifo_size(1000); long_hostnames(off); check_hostname(yes); keep_hostname(yes); chain_hostnames(no); use_time_recvd(yes); }; template("$MSGONLY\n") When I perform a TCPDUMP and view the incoming message and then the forwarded message I can see that syslog-ng adds more data to the MESSAGE aspect of the syslog. Has anyone been able to create a filter or template that manages this format, so that the forwarding of the syslog onto another receiver is not changed as syslog-ng is adding the $DATE and $HOST to the message.

[PATCH 0/1]: value-pairs key rewriting for 3.4
by Gergely Nagy 21 Nov '11

21 Nov '11

The patch I'll be sending in a followup implements key rewriting for syslog-ng 3.4. I wrote about this quite a bit in the past, and this time, there are no functional changes - it's just the work I've done so far merged into a single patch. ...and updated a bit, because during the merge, I discovered that the transformations are not thread safe, so I took the opportunity to convert them to scratch buffers too. This, however, was done in a bit of a hurry, so I'm not entirely happy with the result. Nevertheless, I'm submitting it as a single patch, mostly so that it can be reviewed in its entirety. I don't think it's ripe for a merge yet, there's a bit of work left to done still, at least in the code part. The functionality itself is - I believe - solid by now. The former branch I worked on (feature/3.4/value-pairs/rekey) will be deleted soon, as it does not contain the latest fixes I applied during the commit merging process. -- |8]

Monitoring syslog-ng logserver
by Paul Muther 19 Nov '11

19 Nov '11

Greetings all, I have a question about monitoring syslog-ng itself. In the event that the log server stops listening or stops processing for messages for whatever reason is there a way to alert on hosts that messages are being queued/buffered? In a situation recently the log server syslog-ng process was running but not accepting log messages from remote hosts for some reason. As a result they all pilled up at the sources until the clients rolled over. It would be helpful to have an alert that it is happening but I can't find anything on monitoring the buffers. Thanks much, PM

patterndb
by Gianluca Tranelli 18 Nov '11

18 Nov '11

Good morning everybody, the time is very good here in Rome, but I don't want to talk abbout the weather but about patterndb that is driving me crazy. After reading all the administration guide v3.3, I found an example of using patterndb to log the duration of an ssh Linux and to log a new formatted message. I just copied the XML, ran update-patterndb but nothing happen. Do i miss something? Can someone post a complete working example on ssh? Patterndb is driving me crazy. Thank you in advance.

Query regarding syslog-ng
by Ankit Mahawar 18 Nov '11

Hi , In c++ we have a function syslog for logging data into the log file . Similar function can be used in syslog-ng for logging or there is a separate function I am totally new to syslog-ng.

Simple config question
by Miguel Alvarez 18 Nov '11

18 Nov '11

Hi, After being less than impressed with the stability of rsyslog, I just discovered syslog-ng and it looks really impressive but a bit overwhelming! I have a simple configuration with my existing rsyslog set up where it's performing normal system syslog responsibilities but also tagging other log files and then forwarding them to a centralized log server. The examples I've seen for syslog-ng are making my head swim so I was hoping someone would be able to point me in the right direction on how to do the same with syslog-ng. Thank you

syslog-ng fails to drop file handles and reopen on HUP signal
by Dave Rawks 17 Nov '11

17 Nov '11

Since 3.3.2 I've been seeing this weird behavior where syslog-ng fails to reload cleanly on a HUP. This has been particularly hard to troubleshoot since it appears as though when the reload fails it is causing both sshd and login to block; which I suspect is because /dev/log has disappeared. Luckily I do have nagios nrpe setup to allow me to remotely restart syslog-ng which alleviates the inability to login, but also makes it very hard to collect any troubleshooting information. Anyone else seeing any failures like this? I also sometimes see a a kernel error like one of the following on reload: Nov 17 10:30:02 app-bogus kernel: [ 3788.489852] syslog-ng[28520]: segfault at 7fd054022350 ip 00007fd054022350 sp 00007fffc93404e8 error 15 OR Nov 17 10:32:35 app-bogus kernel: [ 3941.605005] syslog-ng[29805] general protection ip:7fd05f0bcc4e sp:7fd05ac71240 error:0 in libsyslog-ng-3.3.2.so[7fd05f092000+7b000] I was really excited about the features this version of syslog-ng has brought with it, but I'm finding it WAY to unstable to use in production. Is there any information I could provide to help resolve these possibly related issues? -Dave
