Newer libtool and autoconf versions?
by Corinna Vinschen 23 Feb '11

23 Feb '11

Hi, Right now, the current 3.2.1 sources can't be build on Cygwin. Apart from two minor problems which are fixed in git (bugzilla items 101 and 102) and a refresh of the files in contrib/cygwin-packaging (bugzilla entry 103), there's a somewhat more troubeling problem. The source tarballs contain libtool/autoconf-generated files which have been created with older versions of these tools, namely libtool 2.2.6b and autoconf 2.65. In order to get a working libtool *.la dependency mechanism on Cygwin, these files have to be created with pretty new versions of libtool/autoconf, right now at least libtool 2.4 and autoconf 2.67 (automake is not affected). Otherwise, with the old versions, building the shared libs fails due to a libtool bug. While I can rectify this situation locally by running autoreconf, it would be nice if building syslog-ng from a tarball would work out of the box on Cygwin, just as on other systems. So, here's my question: Is it possible to generate subsequent source tarballs using these newer versions of libtool and autoconf? Thanks in advance, Corinna -- Corinna Vinschen Cygwin Project Co-Leader Red Hat

Help required for Syslog-ng compilation on AIX 5.2.

Hi, I need some urgent help or advice to address a make error that I am getting during my compilation of syslog-ng on AIX machine using the --enable-static-linking option I am using gcc3.3.2 versoin.

[Bug 113] New: hang on disk access seem to cause network logging to stop
by bugzilla＠bugzilla.balabit.com 23 Feb '11

23 Feb '11

https://bugzilla.balabit.com/show_bug.cgi?id=113 Summary: hang on disk access seem to cause network logging to stop Product: syslog-ng Version: 3.0.x Platform: PC OS/Version: Linux Status: NEW Severity: normal Priority: unspecified Component: syslog-ng AssignedTo: bazsi(a)balabit.hu ReportedBy: arekm(a)maven.pl Type of the Report: bug Estimated Hours: 0.0 syslog-ng deadlocks in some disk operation (faulty hardware; controler somehow locks up etc) then network logging to another host is also stopping. This is very unfortunate because network logging could give provide me a hints on why disks deadlocks etc. Also if we have few hard disks mounted in /mnt/test1, /mnt/test2, we log things into /mnt/test1/logfile, /mnt/test2/logfile and test test1 disk deadlocks then syslog-ng will also stop logging to test2/logfile. Basically one deadlocked device locks everything else.

using correlation to filter out some messages ?
by Guillaume Rousse 22 Feb '11

22 Feb '11

Hello. I've had a look at message correlation in the 3.2 manual, but it's still a bit obscure for me to understand if it could allow me to achieve filtering of pairs of log messages, as described here: https://lists.balabit.hu/pipermail/syslog-ng/2010-January/013857.html -- BOFH excuse #360: Your parity check is overdrawn and you're out of cache.

abandon libdbi and write a new sql driver?
by Patrick H. 22 Feb '11

22 Feb '11

Reading through the mailing list lately I've seen a fair amount of problems reported with libdbi. Given that it also doesnt support prepared statements which is a very important feature, I'm wondering if libdbi should just be dropped entirely. Libdbi seems to be of use to applications that want just very basic sql support, and not for anything involving high performance or reliability. I know its no small undertaking to write a new DBI for all the common databases out there, but if syslog-ng is supposed to be high-performing, libdbi does not fit in with that. I dont know if it'd be best to start a new project to replace libdbi but accomplish the same thing of providing a common API for all databases, or to just write separate modules for syslog-ng 3.2+ for each database out there. Writing modules would certainly be easier as they could be written independently by people who best know each database API. This is all just my opinion, but I for one am all for it. In my production environment, we do logging to a database, and libdbi just didnt have the flexibility or performance we needed, so I ended up writing a separate program which connects to the database to perform the inserts. Would be nice to avoid having to do that. I know I've also heard many recommendations of piping out to a perl script to do the inserts. A perl script should never do its job faster than C code. -Patrick

syslog-ng 3.2.2 OSE takes 100% CPU after source files get truncated.
by Mailing Lists 22 Feb '11

22 Feb '11

Hi, Not sure if syslog-ng has a bug tracker, but I couldn't find one anyway, so posting this here. Here is the problem: I have source file that is a log file that is been truncated periodically (by log rotate). When the truncation happens syslog-ng process starts taking 100% CPU, and not doing any logging. This behavior remains until source file receives a write. To reproduce: 1. configure syslog-ng with following lines: source s_logfiles { file("/var/log/applogs/mysql/mysqld.log" flags(no-parse) program_override("mysqld.log")); file("/var/log/applogs/mysql/mysql-slow.log" flags(no-parse) program_override("mysql-slow.log")); }; destination d_mysql_logall { file("/var/log/mysqlall.log"); }; log { source(s_logfiles); destination(d_mysql_logall);}; 2. start syslog-ng 3. output some text into source files: for i in /var/log/applogs/mysql/mysqld.log /var/log/applogs/mysql/mysql-slow.log ; do echo "some text" >> $i; done 4. truncate source files: for i in /var/log/applogs/mysql/mysqld.log /var/log/applogs/mysql/mysql-slow.log ; do > $i; done 5. observe syslog-ng takes 100% CPU, doing nothing. 6. output some text into source files again: for i in /var/log/applogs/mysql/mysqld.log /var/log/applogs/mysql/mysql-slow.log ; do echo "some text, again" >> $i; done 7. observe syslog-ng returned to normal operation. comment: some times you'll need going through steps 3 - 5 a few times to trigger the bug. My config: syslog-ng 3.2.2 Installer-Version: 3.2.2 Revision: ssh+git://bazsi@git.balabit //var/scm/git/syslog-ng/syslog-ng-ose--mainline--3.2#master#1d3f396485eb47b1ff6aa18ac4f1c4cd51c0ea4c Compile-Date: Jan 20 2011 11:34:35 Enable-Threads: off Enable-Debug: off Enable-GProf: off Enable-Memtrace: off Enable-Sun-STREAMS: off Enable-IPv6: on Enable-Spoof-Source: on Enable-TCP-Wrapper: on Enable-SSL: on Enable-SQL: off Enable-Linux-Caps: off Enable-Pcre: on Enable-Pacct: off Regards.

filter/parse based on certificate attributes?
by Christian Tramnitz 22 Feb '11

22 Feb '11

With syslog 3.0 and ssl support using mutual certificate authentication is it possible to parse/filter/tag based on attributes in the certificate? I'd like to have a common listener and then relay or append messages based on client-cert attribute values... (Sorry if this message is arriving more than once, I seem to have problems with posting through Gmane.) Regards, Christian

dbtype in SQL logging
by Hendrik Visage 22 Feb '11

22 Feb '11

Hi there, found the following entry in the Administrator's guide(s): <quote> columns Type: string list Default: "date", "facility", "level", "host", "program", "pid", "message" *Description:* Name of the columns storing the data in *fieldname [dbtype]*format. The *[dbtype]* parameter is optional, and specifies the type of the field. By default, syslog-ng creates *text* columns. Note that not every database engine can index text fields. </quote> So now before I go search the source code for answers, what types of "[dbtype]" is supported/handled by syslog-ng 3.2.2? More precisely, I'm running on HP-UX 11.31 and preference is using PostgreSQL Thank you HEndrik
