I've found a way to send the message to an email address. It's a bit of a hack, but.. Basically you output your log to a file, and have a cron job that watches for that file, emails its contents, and deletes it. I'm using it to email a pager. 1- Configure your source line properly for the type of log you are catching 2 - Add a destination file rule 3 - Add a filter to filter for what you're looking for 4 - Add a log with above source, filter, and destination 5 - Install this script in /usr/bin or wherever 6 - Add a cron job such as the example that follows Sample syslog-ng.conf ------------------------------------------ options { sync (0); time_reopen (10); log_fifo_size (1000); long_hostnames (off); use_dns (yes); use_fqdn (no); create_dirs (no); keep_hostname (yes); }; source s_sys { unix-stream ("/dev/log"); internal(); }; source s_remote { udp(ip(0.0.0.0) port(514)); }; destination d_powerpay { file("/var/log/powerpay"); }; destination d_powerpay_email { file("/var/log/powerpay_email"); }; filter f_emerg { level(emerg); }; filter f_powerpay { facility(local1); }; log { source(s_remote); filter(f_powerpay); destination(d_powerpay); }; log { source(s_remote); filter(f_powerpay); filter(f_emerg); destination(d_powerpay_email); }; log { source(s_remote); filter(DEFAULT); destination(d_mesg); }; ------------------------------------- Sample cron entry ------------------------------------ 5,10,15,20,25,30,35,40,45,50,55,0 * * * * /usr/bin/mail_log.sh /var/log/powerpay_email inet_admin(a)ceridian.ca ----------------------------------- mail_log.sh script ----------------------------------- #!/bin/bash # # mail_log.sh # by John Delisle john_delisle(a)ceridian.ca # Feb 28 2001 # # # If a file $1 exists, it mails its contents to $2, and deletes $1 # # MAILPROG="/usr/sbin/mail" if [ $# != 2 ]; then echo "Usage: $0 file_to_check email_address" exit 1; fi if [ ! -e $1 ]; then #echo "$1 not found, exiting" exit 2; else $MAILPROG $2 < $1 echo "Message Sent to $2"; echo "Removing $2"; rm $2 fi exit 0; ----------------------------------- John Delisle Corporate Technology Ceridian Canada Ltd 204-975-5909 John_Delisle@ceridian. ca To: syslog-ng(a)lists.balabit.hu Sent by: cc: syslog-ng-admin@lists.

Re: [syslog-ng]AIX compatability issue?
by John_Delisle＠ceridian.ca 28 Feb '01

28 Feb '01

I've discovered the problem. It seems AIX sends a 'verbose' string by default. If you add a -s to the line where you call AIXs syslogd from it sends a more typical message. After this change all my AIX messages are filtered correctly.

Below is the output I get strace and truss log to stderror (or a file) all the system call a process makes. I took a look at the AIX box we have kicking around and the only strace on it is for tracing STREAMS. This is not what you want. I looked at the strace homepage, and as far as I can tell, AIX is *not* one of the supported platforms. AIX seems to have a tracing utility called trace(1). It looks kinda odd, but should do the job. ---------------------------------------------------------------------------- __o Bradley Arlt Email: arlt(a)cpsc.ucalgary.ca o__ _ \<_ WWW: www.acs.ucalgary.ca/~bdarlt _>/ _ (_)/(_) -Eat well, sleep peacefully, drink lots, and ride like hell.

RE: [syslog-ng]Trying to send log over network
by Hamilton, Andrew Mr RAYTHEON 5 SIG CMD 28 Feb '01

28 Feb '01

Sim, I have just a couple of other questions. What is the address of your loghost and the address of the clients? I'm looking at your two configs and I want to make sure that the destination for the problem machine is ok. Do you have a 192.168.1.19 host on your network and is it listening for tcp connections on port 514? In the loghost config you reference a source of 192.168.1.1 which tells me that your loghost is 192.168.1.1. If you are trying to establish a connection to a host using the tcp/ip you also need to make sure that the host is listening for tcp/ip connections. The loghost config is listening for tcp/ip on 192.168.1.1 port 10001 and you are trying to make a tcp connection with 192.168.1.19 on port 514. Is this what you are intending, if so this won't work. Change your destination in your client to read destination d_bg {tcp("192.168.1.1:10001") }; That should at least let you log to that loghost.

Newbie intro/question
by Dave Carmean 28 Feb '01

28 Feb '01

Greetings from a list newbie. I discovered syslog-ng the other day while STFW for more info about logsurfer, which I've been trying out recently. I've looked at the list archives for several months back, but don't see obvious answers to the following: - Are people using -ng to perform noise filtering and/or alerting a-la Swatch, WOTS, logsurfer, etc? Or is most filtering just to effectively increase the number of facilities by sorting on reporting program name? - Has anybody devised a way with -ng to monitor the repeat rate of a particular message? I.e. if you get 10 log_info messages per hour from named on host foo, ignore them, but if you get 100, save them and trigger some event? - I would like to embed the message's facility/level into the recorded message text, similar to what SGI's Irix' syslogd does, although probably in human-readable form rather than an octal number. Maybe I'm looking in the wrong docs, but I'd like to write something like this to the output channel: "Feb 27 01:31:05 foo sendmail[nnn]: ${FACILITY}/${PRIORITY} \ $rest_of_message" I'll go RTFM some more, but if anybody can give some basic answers, I'd be grateful. Thanks. -- Dave Live fast. Die young. Leave a good-looking audit trail.

(OT) routers and host matching
by Brian E. Seppanen 27 Feb '01

27 Feb '01

Hi: Sort of off topic, but someone here might be more familiar with this situation. I monitor several routers with syslog-ng on a central host. One problem I'm facing is that I want to redirect logs dependent upon the router to different files. This works well, but I have one problem. We do not use DNS to resolve names, and we match upon host IP's. The problem is that the routers have several possible IP's and I'm finding that more and more often that I don't have a filter defined for certain IP's. My syslog-ng config is already a god awful mess and I'm hoping that I'm being short sighted and that there is a solution to my quandry. Is it possible to have the router log via one interface and therefore guarantee a host IP match? Has anyone found a way to work around this? I'd really appreciate any insight. thanks, Brian Seppanen Charter Communications Regional Data Center 906-228-4226 ext 23 Marquette, MI seppy(a)chartermi.net
