Re: [osol-discuss] syslog-ng?
It would be nice if something was done about the current syslog. The last time I used it for centralized logging, things didn't quite turn out like I hoped. Solaris' syslog is limited, delicate, and only supports UDP. Also, I found a bug where the workaround was in an email from 1994 or 1996.

Considering that we need to call that door *every time* we log a message, wouldn't that be *really* expensive? I'm afraid that will pull in a few extra libraries into libc. The current code is broken: /* output the message to the local logger */ if ((putmsg(LogFile, &ctl, &dat, 0) >= 0) && syslogd_ok()) return; if (!(LogStat & LOG_CONS)) return; The call to syslogd_ok() should be done *after* checking that LOG_CONS is set and the putmsg() failed.

It logs the messages in some stream device. (/dev/sysmsg or some such). Clearly syslog-ng needs to be able to pick up such messages *and* create a door where it can say "yes, I'm still running".

I was able to compile and install it using http://pkgbuild.sourceforge.net/ a) Install SFE environment and build pkgtool and cd /path/to/build/of/packages/spec-files-extra.2009116 b) pkgtool build-only --svr4 --download --autodeps --interactive SFEeventlog.spec (build-only, because installation failed - requires manual intervention) pfexec pkgadd -d /path/to/build/of/packages/PKGS SFEeventlog (install package) c) pkgtool build --svr4 --download --autodeps --interactive SFEsyslog-ng.spec In step c) you will have build and installed syslog.ng package: pkginfo | grep SFE SFE SFEeventlog Library needed by Syslog-ng SFE SFEsyslog-ng Syslog-ng tries to fill the gaps original syslogd's were lacking SFE SFEsyslog-ng-rootSyslog-ng tries to fill the gaps original syslogd's were lacking - / filesystem Note that i have used svr4 option (you can experiment with IPS, but you need too install local IPS server) Regards. -- This message posted from opensolaris.org ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org

I'm running syslog-ng-2.0.5, and it was essentially a no-brainer. Just
./configure CC=cc CFLAGS=-O
make
make install
> ./config.status --version
config.status
configured by ./configure, generated by GNU Autoconf 2.61,
with options "'CC=cc' 'CFLAGS=-O'"

I knocked up an SMF service for it. (I just copied the standard syslog

My biggest problem with the code is that syslogd_ok() is always called, even when we're not using the data. Casper ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org

I doubt that if it were installed on OpenSolaris that it would work for processing logs for local programs. This is because the things that do the logging are going to use libc's implementation of syslog(3C), which logs via a door (see libdoor(3lib)). Doors are unique to [Open]Solaris and as such syslog-ng is unlikely to be listening for log messages at /etc/.syslog_door. -- Mike Gerdts http://mgerdts.blogspot.com/ ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
