new macro feature request
by Nate Campi 21 Feb '02

21 Feb '02

I sort logs by hostname, but often the hostname field is wrong, containg a program name (from some solaris hosts) or a severity level (some network devices). Would it be possible to add a macro for the client IP/hostname? Instead of logging like this: destination hosts { file("/var/log/HOSTS/$HOST/$YEAR/$MONTH/$DAY/$FACILITY$YEAR$MONTH$DAY" owner(root) group(logs) perm(0644) dir_perm(0755) create_dirs(yes)); }; I could log like this: destination hosts { file("/var/log/HOSTS/$gethostbyaddr/$YEAR/$MONTH/$DAY/$FACILITY$YEAR$MONTH$DAY" owner(root) group(logs) perm(0644) dir_perm(0755) create_dirs(yes)); }; This way, /var/log/HOSTS/unixbox gets the log that the host "unixbox" sent even if the message itself is formatted incorrectly. Man I wish I knew C and could supply patches. Maybe I'll finally apply myself to the K&R C book soon and see what I can churn out ;) -- Nate "Mac users swear by their Mac, PC users swear at their PC."

Not writing to new logfile after rotate and restart
by Livens Wim 21 Feb '02

21 Feb '02

I have a rather straightforward syslog-ng.conf. I write all messages from the local host to /var/adm/messages and things that come from the net to a separate (customer specific file) filtered on the source host. All works well except that I can't rotate the customer specific logfiles. I can rotate /var/adm/messages. doing: # mv /var/adm/messages /var/adm/messages.0 # kill -HUP `cat /etc/syslog-ng/syslog-ng.pid` and new log are written to /var/adm/messages BUT: # mv /data/customer-logs/491 /data/customer-logs/491.0 # kill -HUP `cat /etc/syslog-ng/syslog-ng.pid` and new messages are still written to data/customer-logs/491.0 I also tried stopping and starting syslog-ng and moving the file somewhere completly different. It still magically remembers the old file. Any idea ?? Relevant part of my config: source local { sun-streams("/dev/log" door("/etc/.syslog_door")); internal(); }; destination syslogfile { file("/var/adm/messages"); }; log { source(local); destination(syslogfile); }; source net { udp(); }; filter filter491 { host("12.34.56.78");}; destination logfile491 { file("/data/customer-logs/log491" perm(0644)); }; log { source(net); filter(filter491); destination(logfile491); }; (I'm using syslog-ng-1.4.14 on SunOS 5.8 sparc) Thanks, -- Wim Livens.

Buffer size for message
by Gehring, Andrew x66132 19 Feb '02

The buffer size for messages in syslog is 1024. I assume it is the same in syslog-ng. Is there any reason that I can't make this larger... Very long story as to why... Thanks, Andrew

log rotation not completing
by Len Conrad 15 Feb '02

15 Feb '02

FreeBSD 4.5R and syslog-ng 1.1.14. We have FreeBSD newsyslog rotate /var/log/maillog and /var/log/pop-before-smtp at 00:00. the rotation is working, we get the .0.gz files and new log files, but newsyslog-ng is apparently not receiving or reacting to the -HUP or whatever newsyslog sends after rotating the files, so logging to the new files stops at 00:00. We don't have this problem with FreeBSD syslogd. We run syslog-ng witht the standard .conf file delivered with the FreeBSD package and installed with pkg_add, with a couple of our lines added for filtering. eg, the pop-before-smtp log shows : Feb 15 00:00:00 buzzard newsyslog[2885]: logfile turned over Feb 15 03:13:45 ns1 POP3D (0000066C) logon success for nnn navymars.org from 66.26.185.182 no logging until we -HUP manually at 3:13. same situ with maillog. suggestions?

log files showing short name.
by Yan Lau 15 Feb '02

15 Feb '02

Hello, I am using syslog-ng 1.5.14. I am trying to get the log messages to display the full hostname instead of the short name. For instance, Feb 4 10:06:42 mailhost su: 'su toto' succeeded for ylau on /dev/pts/0 We have several servers with the name "mailhost" so I would like it to show mailhost.nyc1.globix.net so I can tell which one it is. Here are the options I have set: options { sync (0); time_reopen (10); log_fifo_size (1000); create_dirs (yes); chain_hostnames (no); use_dns (no); use_fqdn (yes); }; Where is it picking up the short name and how can I get it to show the full name? Sometimes the log shows IP addresses, that is OK. Thanks, Yan.

Having trouble with the options syntax for file permissions
by Leonard Mills 15 Feb '02

15 Feb '02

Running v.1.5.13 Couldn't find likely questions in the archives, going to the list. I have been getting several gigabytes per day in the logs of entries similar to (line broken for length considerations: Feb 13 00:28:04 admin monitor_mail(a)admin.sjc.in.sel.sony.com: [daemon.info] monitor_mail(a)admin.sjc.in.sel.sony.com[24759]: connect from hpntbox1.corpnet.sel.sony.com To try and prevent these, I tried changing the conf file by adding: # DESTINATION ... destination trash { file("/dev/null"); }; ... # FILTER ... filter f_trash { match("connect from hpntbox1.corpnet.sel.sony.com"); }; ... # first exact rule log { source(src); filter(f_trash); destination(trash); flags(final); }; That works. Of course, the daemon then goes ahead and puts the default mode (0600) on /dev/null, which is not a good thing. I haven't been able to decipher a proper syntax for the options in the destination line. My best hints seem to have been in section 2.5 of the reference manual, so I tried: destination trash { file("/dev/null" options{perm(0666);}; ); }; But this gives a syntax error. Also tried eliding the options as in destination trash { file("/dev/null" perm(0666);); } to no avail. Obviously I'm missing something simple, but can't see it. TIA for any hints, Len

Sorting based on incoming hostname.
by Konstantin Riabitsev 15 Feb '02

15 Feb '02

Hi, folks: I am trying to achieve the following setup. Say, I have Solaris boxes and Linux boxes on my network, and I want them all to log to one loghost. However, I would like to separate the incoming logs by system type. I had this idea: Solaris boxes would log to log-sol.domain.com, while Linux boxes would log to log-lnx.domain.com, which are both CNAME's to loghost.domain.com. Would it be possible for syslog-ng to put all solaris logs in /var/log/solaris and linux logs into /var/log/linux, based entirely on which hostname they arrived at?

I added documentation in the patch I sent. Yes, remove_if_older requires one parameters, stating the number of seconds (it was days in my patch, but Balazs changed that to seconds to match all other syslog-ng parameters). If the file where the log line is to be written to is older than the number of seconds specified, the file will be removed prior to writing the log to file. Thus it is a parameter of the file() destination. I originally though about implementing some other features, like the ones you described, but because our product (which uses syslog-ng as logger) doesn't need those features, my boss didn't allow me to work on those. It shouldn't be too complex to add, by the way. You can take my patch as a basis for knowing where to change the source code. Groetjes, Klaas van Gend

Why can't I get NOT to work in a filter?
by Chad White 13 Feb '02

13 Feb '02

Hi all, I am trying to filter out some things from my log files using a filter with a NOT command and I can't get it to work. I am running Syslog-ng 1.4.14 on Solaris 8 (SPARC). What I am trying to do in this case is ensure that sudo doesn't get logged into my /var/adm/messages file. Here are the pertinent lines of my config file: options { dir_perm(0755); perm(0640); owner(root); group(wheel); chain_hostnames (no); keep_hostname(yes); }; source local { sun-streams("/dev/log" door ("/etc/.syslog_door") ); internal(); }; filter not_sudo { not facility(local2); }; filter notice_emerg { level(notice...emerg); }; destination messages { file("/var/adm/messages" create_dirs(yes)); }; log { source(local); filter(notice_emerg); filter(not_sudo); destination(message s); }; Now, it is my understanding that the filters are AND'd together so that log statement should basically say "log everything with a level between notice and emergency unless it is facility(local2)." However, I am still getting this is my log files: Dec 30 03:32:24 hqmon /usr/local/bin/sudo: [ID 850335 local2.notice] nobody : TTY=unknown ; PWD=/opt/bb18d ; USER=root ; COMMAND=/usr/sbin/vxdisk check rootdisk Also another filter that dumps everything from facility(local2) does dump all the sudo stuff into a file like I want.. Starting to feel like an idiot since I can't get this to work. Can someone give me some pointers to filtering out just a few cases based on facility or strings? thx, --Chad

Splitting UDP syslog traffic
by Eduardo Seud�nimo 13 Feb '02

13 Feb '02

I'm interested in doing a 'tee' to syslog traffic much in the same way that the tee command does to stdout. I currently have a syslog-ng server that gets a whole lot of traffic sent his way. Because of bandwidth contraints, I do not want to double the traffic flow by sending it to two servers. I would like to have a way to listen for the incoming syslog traffic and redirect each packet to a different IP address while preserving the original packet destined for my syslog box. For each packet that looks like this: source IP ----> syslog server IP I want two packets like this: source IP ----> syslog server IP source IP ----> syslog server2 IP This will allow me to send a stream to both servers while preserving the bandwidth to the remote sites. I need to preserve the source IP traffic because I'm using sysng to break it up into seperate paths/files based on source. Is this possible with NG? It looks like NG will bind to a local address when using the udp destination driver.
