What does your config file look like, here is an ex, of mine, i use filters to to force the host to log to the text file. ## tking switch 192.168.3.254 destination 192.168.3.254 { file("/var/log/routers/tking-switch.log"); }; filter f_192.168.3.254 { host(192.168.3.254); }; log { source(net); filter(f_192.168.3.254); destination(192.168.3.254); }; michael http://vw.vermeer.org/syslog-ng/ >>> rob(a)rascal.ca 01/19/02 18:23 PM >>> Hi everyone, I'm pretty new to syslog-ng, but I really like it so far, except for one thing I can't figure out...(it could be a clueless newbie issue.)

log rotation features for syslog-ng
by klaas.vangend＠philips.com 24 Jan '02

24 Jan '02

Gentlemen, I'd like enhance syslog-ng with some features in order to get rid of some log rotation scripts. For some of our systems, we log on a centralised system, but also store the logs locally. These logs only need limited availability, say a week or so. The file() destination currently is already able to use the target $WEEKDAYS (which is undocumented, btw), but in that case, logs from both Jan 17 and Jan 24 are logged in messages.Thu.log Therefore, I'd like to add a new option clear_old(X) which removes a logfile with a timestamp older than X days prior to writing the new message to that file. (default should be 0 (=never), which means that for a disabled feauture only one C 'if' statement additional overhead is caused) But I can imagine that people also wants to set a max size on a logfile. E.g. to be able to compress it afterwards, or for simple log rotation, like: file('/var/log/mesages' max_size_old(200, 'gzip')) will rename the existing 200 kB file to /var/log/messages.old and then run 'gzip /var/log/messages.old' Maybe it is better to add a new destination rotatedfile(), maybe it's better to do something else... I'd to know wheter everyone agrees that these features are a good idea, and that the proper approach is taken to keep the configurationfile syntax simple. Groetjes, Klaas van Gend

Syslog-ng on Boot
by jesse.keefe＠convergys.com 23 Jan '02

For those who asked about starting syslog-ng on boot, here is what I did for Solaris 8. I simply modified the /etc/rc2.d/S74syslog script: case "$1" in 'start') if [ -f /etc/syslog-ng/syslog-ng.conf -a -f /usr/sbin/syslog-ng ]; then echo 'syslog-ng service starting.' # # Before syslogd starts, save any messages from previous # crash dumps so that messages appear in chronological order. # /usr/bin/savecore -m if [ -r /etc/dumpadm.conf ]; then . /etc/dumpadm.conf [ "x$DUMPADM_DEVICE" != xswap ] && \ /usr/bin/savecore -m -f $DUMPADM_DEVICE fi if [ ! -f /var/adm/messages ]; then /usr/bin/cp /dev/null /var/adm/messages /usr/bin/chmod 0644 /var/adm/messages fi /usr/sbin/syslog-ng >/dev/msglog 2>&1 & fi ;; 'stop') echo 'syslog-ng service stopping.' if [ -f /var/run/syslog-ng.pid ]; then syspid=`/usr/bin/cat /var/run/syslog-ng.pid` [ "$syspid" -gt 0 ] && kill -15 $syspid fi ;; *) echo "Usage: $0 { start | stop }" exit 1 ;; esac ------------------------------------------ Jesse Keefe <jesse.keefe(a)convergys.com> | Systems Administrator | Convergys Corp. | 229 West Seventh Street | P.O.

Logging to mysql
by Richard Wallace 22 Jan '02

22 Jan '02

Hello, I've setup a rule to send all log messages received for the local0 facility to a program which then inserts info into a local mysql database. The problem is this isn't working. The script doesn't appear to be being called, since there are no messages in the mysql.log file stating that anyone has tried to connect. Here are the lines I've added. Any help would be greatly appreciated. destination local0 { program("/usr/local/sbin/rsynclog.pl"); }; filter f_local0 { facility(local0); }; log { source(src); filter(f_local0); destination(local0); }; Thanks -- _ Richard Wallace /\ | | /\ /| AIM, Inc.

This is probably also why syslog-ng does not have a problem with this case, it gets logged as: Jan 17 08:11:21 hwdf0006/hwdf0006 PAM_pwdb[22525]: (sshd) session close so syslog-ng correctly adds time and hostname to the log entry. The format of linux (and others) is: <Prio>message The format of the SSR is: <Prio>datetime<space>message The format the RFC suggests is: <Prio>datetime{space}hostname{space}message >It is up to the relay/collector to input the complete header. this is my understanding from the rfc too, but how do I get this using syslog-ng ? >I missed the beggining of this thread, is "%ACL_LOG-I-DENY" getting set >as your hostname?

That would save the day for me, but I don't know >how hard it would be to implement that. Well I would vote for getting a setting just the other way around, so for being able to configure something like options( addhostname(<pattern>) which would lead to the hostname being added if the pattern is matched and the pattern then being treated as part of the message. For me this just would be a '^%' as every message of the ssr is prepended with the percent sign ;-) still do not know how much work it would be but ..... BTW: I do not know how the linux syslog does it, but it does not have this problem. Maybe because '%' is not a valid char for hostnames. linux syslog is a pretty standard syslog I'd guess, though you could argue, wether this is correct according to the standard. Linux syslog displays the message above as: Jan 13 04:02:12 1.2.3.4 %ACL_LOG-I-DENY, ACL [280] on "rtfa" UDP 192.168.1.2:4721 -> 14.9.1.3:53 so it automagically adds the ip address to the message. Again maybe because of the '%' and ',' signs inside the string at the <hostname> position. >-- >Nate Campi <http://www.campin.net> GnuPG key: 0xC17AEF79 Kind regards, Patrick Hildenbrand > Patrick Hildenbrand > Operations & Technology > SAP Hosting AG & Co.

Leaky syslog-ng files?
by Rob Mitzel 20 Jan '02

20 Jan '02

Hi everyone, I'm pretty new to syslog-ng, but I really like it so far, except for one thing I can't figure out...(it could be a clueless newbie issue.) I'm using syslog-ng on FreeBSD 4.4 to log everything for about 10 cisco routers/switches right now, with about 30 more that will be added over the next week or two. I have them logging to separate files right now, and that works great, with newsyslog archiving stuff, etc etc. Works wonderfully. However, everything keeps leaking into my /var/log/messages file, which I don't want it to do. I *just* want it in their separate files. An example of what I use for filters is: filter f_gig2 { host("gig2-0"); }; And for log: log { source(src); filter(f_gig2); destination(gig2); }; And for destination: destination gig2 { file("/var/log/peer1/vancouver/gig2-0"); }; Anyone have any suggestions? Thanks in advance! -Rob.
