The syslog-ng no this playing the messages for logs, and the following message appears when start syslog-ng : "Internal messages are not referenced, they'll go to /dev/null" what I must make ?

You need to add the syslog door to the source list. I use this source on the 5.6 systems source local { sun-streams("/dev/log" door("/etc/.syslog_door") ); internal(); udp(ip(0.0.0.0) port(514) ); }; and this one on 5.8 systems source local { sun-streams("/dev/log" door("/var/run/syslog_door") ); internal(); udp(); }; The cluster messages go to the local0 facility by default. The switch over messages come out as local0.err. It is a really good idea to replicate the cluster messages to a local file and to the console. If you have a public network failure and the cluster reconfigures the messages will be lost.

Mahlon, >My eventual goal is to have one 'logging server', receiving logs from all >of the other servers around here, and parsing/pushing them into a mysql >database. We've implemented basically the same topology here, but instead of "mysql"ing the messages we're parsing and monitoring the lot of them looking for those (repeated login failures within or across system(s), etc..) which might concern us. What we did was write all messages to named pipes, one for each priority level. We made our perl script a daemon which reads the messages out of the named pipes. One of the perceived advantages here was that all buffering is provided by the OS. Our central server (AIX) comfortably supports over 50 disparate clients (AIX, Sun, NT) and handles an average of 310000 messages a day. (We had an anomalous day two weeks ago with 800000 messages with no observed problems.) The only significant disadvantage we've encountered is that our daemon has to be running before syslog-ng is started, this due to syslog-ng rightfully failing to startup if the named pipes are not open, something our daemon does. Good luck, John

syslog-ng dying on hup

Re: syslog-ng vs (of all things) Win2k + IIS
by wolfgang.braun＠gmx.de 21 Oct '00

Some thoughts to this. I refer to the machine collecting logs as server, the machines writing logs to it as clients. 1) TCP Connections syslog-ng uses persistent connections to clients logging to the server. It has been argued that TCP has some overhead over UDP. Now imagine you have 300 clients logging to your web server/CGI. Using HTTP you have to create a new connection every time a client wants to write logs to your server. If persistent TCP has _some_ overhead, this can only be called *huge* 2) Calling CGI Every time you want to log to the server it has to exec your CGI. 300 clients logging simultaneously, each forcing the server to exec the CGI over and over again. There's a reason people came up with ASP, PHP, embedded <script> and servlets: overhead in loading, linking and executing the called program. It get's even worse when you're using an interpreted language, since then every time the interpreter has to be loaded again. 3) File handling syslog opens local files once, keeps the fd and flushes its message queues from time to time. With CGI you have to open,write,close your files everytime a client delivers his logs. 4) Managing logs on the server with generic syslog you have some liberty to define which logs get written to which file, based on priority, facility or even regexps. on the opposit you're very limited on where you write to. if you let each instance of your CGI write to a file i imagine it could get a bit messy. Even if you build a system as proposed (HTTP+CGI), and the server can handle all that overhead the question remains if your homegrown system proves to be anywhere near as reliable as a piece of software that has been specifically designed for the task. -- Those who do not understand Unix are condemned to reinvent it, poorly. -- Henry Spencer

It sucks to have to list the same things 30 times, both for local and remote destinations (on this loghost, anyways). Why can't there be a options { files (owner(root) group(root) perm(0640) dir_perm(0755)); }; as a global option???? It would sure help to keep things a tad bit simpler and cleaner..... Tom

global options problems on Solaris 7/sparc
by Tom Wells 21 Oct '00

21 Oct '00

Hi, I'm putting the following items in the global options section, but syslog-ng keeps complaining about parse errors in my config file, specifically the "owner", "group", "perm", and "dir_perm" options. I'm running libol-0.2.20 and syslog-ng.1.4.7, though it happened with libol-0.2.19 and syslog-ng.1.4.5 as well: ############################# # options ############################# options { use_dns(yes); use_fqdn(no); long_hostnames(off); sync(0); create_dirs(yes); owner(0); group(1); perm(0600); dir_perm(0755); }; Any help would be most appreciated.

Buffering to a program.
by Mahlon Smith 21 Oct '00

21 Oct '00

My eventual goal is to have one 'logging server', receiving logs from all of the other servers around here, and parsing/pushing them into a mysql database. I've got the general topology setup and working - and a perlscript that syslog-ng is pumping the logs to - which in turn is doing the mysql writing. Working fine, except I'd like to control the amount of buffering before it hits the perl program. I have '$| = 1;' in my perl prog, so perl isn't doing the buffering.. it's gotta be syslog-ng. sync(0) is set - and appears to work fine to flat files - just not to a forked program. In fact, I don't really even see it start to write out the buffer to the perl prog until I HUP the syslog-ng process. (which obviously isn't going to help me in the long run.) Any tips/suggestions are appreciated. -Mahlon -- Mahlon Smith InternetCDS http://www.internetcds.com
