Matching against an embedded @
by Peter Mills 17 Sep '10

17 Sep '10

Since @ is a special character, how do you match against strings containing an @? Do you escape them e.g. \@ in order to parse them correctly? I am trying to skip over/match the string [wx-event(a)juniper.net and have had no success.

Pattern Matching Issues
by Peter Mills 16 Sep '10

16 Sep '10

I am new to syslog-ng and just trying to get a basic version 1 XML pattern match file working properly. The output with an associated template is redirected to a file. It currently claims there is no such value. Does this mean that the pattern match has failed? Using syslog-ng (3.0.8) parser p_patterndb { db_parser(file("/opt/syslog-ng/var/db/patterns/v1/test.xml")); }; # Check pattern matching is working log { source(s_ext); parser(p_patterndb); <<<<< destination(df_udp_pattern_output); }; #Check pattern matching destination df_udp_pattern_output { file("/var/log/pattern_output" template("$PROGRAM,${rest},,$MSG\n") template_escape(no)); }; Output of: /opt/syslog-ng/sbin/syslog-ng -e -F -d -v > /tmp/syslog-ng.out 2>&1 Incoming log entry; line='<131>1 - - WXC-192.168.61.202 register 1102 [wx-event(a)juniper.net eventtime="1284626839" metric="Primary Reg Server Unreachable" sev="major" type="sys"] REG: Self registration failed.

syslog-ng under HP-UX processing unwanted "padded" data
by Scott Rochford 16 Sep '10

16 Sep '10

Hi, I'm trying to test syslog-ng under HP-UX 11iv2 (both PA-RISC and IA64) to use as an alternative to the supplied syslogd. I have tried using the precompiled 3.0.5 binaries supplied with HP's DSAU (Distributed Systems Administration Utilities) pack, as well as compiling 3.0.5 and also version 3.1.2 from source. In all 3 cases I have the same problem; it seems to be attempting to process the padded data remaining in the 2048-byte chunk that is read from /dev/log, as you can see from the test below. In other words it does not stop processing the 2048-byte chunk of data when it reaches the first null byte. This means that the first log entry after startup is processed correctly, but then all sorts of random things start to happen, including blank (other than date stamp and host name) messages to every connected terminal. I used gcc-3.4.3, glib-2.24.2, popt 1.16, and pkgconfig 0.25 from the HP-UX Porting and Archive Centre to compile it. Have I overlooked something obvious here? I can't see any other similar reports on this mailing list or in the wild. I'd appreciate any suggestions! Regards, Scott. P.S. It's a little confusing that the HP-UX notes in the INSTALL file and the contrib/syslog-ng.conf.HP-UX files disagree with each other about the source syntax; will these be reconciled in a future release? # nohup /usr/local/sbin/syslog-ng --debug --foreground --stderr > syslog-ng.out 2>&1 & # logger -p user.notice "a user.notice test" # grep Incoming syslog-ng.out | head Incoming log entry; line='<13>Sep 6 05:16:52 syslog: a user.notice test' Incoming log entry; line='L\x84yD' Incoming log entry; line='\x01' Incoming log entry; line='\x01' Incoming log entry; line='\x01' Incoming log entry; line='\x09' Incoming log entry; line='\x01\x90T' Incoming log entry; line='\xd1\x9d' Incoming log entry; line='h\x0f\x1c,h\x0f\x1c\x98@' Incoming log entry; line='[Hh\x0dG\xc4h\x0dG\xc4\xc0\x1d?K\xc0\x1d?\x93' # /usr/local/sbin/syslog-ng -V syslog-ng 3.1.2 Installer-Version: 3.1.2 Revision: ssh+git://bazsi@git.balabit//var/scm/git/syslog-ng/syslog-ng-ose--mainline--3.1#master#8bf13c304b6ab5fc1a372b49d55c78370efe14ca Compile-Date: Sep 6 2010 01:21:23 Enable-Threads: off Enable-Debug: off Enable-GProf: off Enable-Memtrace: off Enable-Sun-STREAMS: off Enable-Sun-Door: off Enable-IPv6: on Enable-Spoof-Source: off Enable-TCP-Wrapper: on Enable-SSL: on Enable-SQL: off Enable-Linux-Caps: off Enable-Pcre: off # cat /usr/local/etc/syslog-ng.conf @version: 3.0 # syslog-ng configuration file. # # This should behave pretty much like the original syslog on HP-UX.

Mass text log files processing over network.
by Tomasz Wrona 13 Sep '10

13 Sep '10

Hello, Could somebody point me if is it possible to configure syslog-ng to automatic, mass, text log files processing over network? Which version eventually support following case? My case: Webservers run virtual servers, which logs their own php error logs [text files]. I want to send this logs to central log server keeping orginal distribution based on virtual servers in the simplest way possible. I would like to have something like this virtual setup: #*** Client config ***# source s_php { # Wildcard match [only for commercial edition?] and TAG it somehow: file("/var/log/php/*-error.log" follow_freq(1) flags(no-parse) TAG("$FILENAME: ")); # eventually manual config for each file if above not possible: file("/var/log/php/service1-error.log" follow_freq(1) flags(no-parse) log_prefix("service1: ")); file("/var/log/php/service2-error.log" follow_freq(1) flags(no-parse) log_prefix("service2: ")); }; destination d_collector_php { udp("collector" port(5501)); }; log { source(s_php); destination(d_collector_php); }; #*** Collector Server config ***# source s_network_php { udp(ip(0.0.0.0) port(5501)); }; # Can I split log stream using MACRO based on custom information send in log [or syslog header]? destination d_php { file("/var/log/hosts/webservers/php/$HOST/$YEAR$MONTH$DAY/$TAG.log"); }; # or maybe: destination d_php { file("/var/log/hosts/webservers/php/$HOST/$YEAR$MONTH$DAY/$log_prefix.log"); }; log { source(s_network_php); destination(d_php); }; Regards Tom

It works for me. So I use parameter log_prefix("service1: ") as equivalent for program_override() on client side and then $PROGRAM.log on server side. However, it is still needed to configure individually each log file [set "prefix/program"] on client side but server process it smart to dedicated files. Regards Tom

syslog-ng is not reading level/facility properly
by Charlie Reddington 09 Sep '10

09 Sep '10

Hi List, After my last weeks note, I kept on doing some more digging. Perhaps some of this output will aid in finding a solution. I compiled from source, from the latest stable 2.0 line thinking maybe that was part of my problem since I installed via the epel repositories. Nope, still having the same problem. On a remote host, I have a nginx server, that is sending it's access logs to local5.notice and it's error logs to local5.crit. In the syslog.conf file I have the following entries. local5.notice @syslog-ng server local5.crit @syslog-ng server This data is definitely making it to the systlog server. I have done a tcpdump and it shows this with the following. Also I have it logging to local log files and they are working the way I expect. $ tcpdump port 514 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes 16:16:40.725473 IP CLIENTIP.syslog > SYSLOGNGIP.syslog: SYSLOG local5.notice, length: 304 <-- coming in as local5.notice as I expect. Okay so they are hitting the server how I expect, but they aren't being filtered the way I expect. Below is my syslog-ng config. # Syslog-ng config options { use_dns(no); keep_hostname(yes); long_hostnames(off); chain_hostnames(off); sync(1); log_fifo_size(1024); create_dirs(yes); perm(0644); stats_freq(3600); mark_freq(600); }; # # Data Sources # # External Syslog source s_external { udp(ip("0.0.0.0") port(514) flags(no_parse)); }; # # Where to put Data # # Nginx / Lighttpd / Apache Access Logs destination d_access_log { file("/data01/syslog-ng/$HOST/ access.log"); }; # Nginx / Lighttpd / Apache Error Logs destination d_error_log { file("/data01/syslog-ng/$HOST/error.log"); }; # Everything else destination d_log { file("/data01/syslog-ng/$HOST/$FACILITY.$LEVEL"); }; # # Data Filters # # Facility local5 filter f_local5 { facility(local5); }; # Level info filter f_info { level(info); }; # Level notice filter f_notice { level(notice); }; # Level warn filter f_warn { level(warn); }; # Level crit filter f_crit { level(crit); }; # Level err filter f_err { level(err); }; # # Data Logging Locations # # Access Logs log { source(s_external); filter(f_local5); filter(f_notice); destination(d_access_log); }; # Error Logs log { source(s_external); filter(f_local5); filter(f_crit); destination(d_error_log); }; # Everything Else log { source(s_external); destination(d_log); }; Now the only place that ANY messages seem to go, is into /data01/ syslog-ng/$HOST/kern.emerg. Why is everything being marked as kern.emerg? And lastly here's some debug output that maybe able to shed some light to those who know more than I do. ./sbin/syslog-ng -d -v -e --cfgfile=./etc/syslog-ng.conf Running application hooks; hook='1' syslog-ng starting up; version='2.0.11' Incoming log entry; line='<156>logger: REMOTEIP www.domain.com - [08/ Sep/2010:17:17:44 -0400] "GET /2010/09/08-7912 HTTP/1.0" 200 83134 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html) "\x0a' Filter rule evaluation begins; filter_rule='f_local5' Filter node evaluation result; filter_result='not-match', filter_type='facility' Filter rule evaluation result; filter_result='not-match', filter_rule='f_local5' Filter rule evaluation begins; filter_rule='f_local5' Filter node evaluation result; filter_result='not-match', filter_type='facility' Filter rule evaluation result; filter_result='not-match', filter_rule='f_local5' For some reason this isn't matching, but I'm officially out of experience on this to know what to do further. I should also note that I'm running splunk on this syslog-ng server and it's able to get my access logs properly. If anyone can throw me a bone here I'd really appreciate it, many thanks in advance.
