syslog-ng.conf sample

#

# Configuration file for syslog-ng under Debian

#

# attempts at reproducing default syslog behavior

# the standard syslog levels are (in descending order of priority):

# emerg alert crit err warning notice info debug

# the aliases "error", "panic", and "warn" are deprecated

# the "none" priority found in the original syslogd configuration is

# only used in internal messages created by syslogd

######

# options

options {

# disable the chained hostname format in logs

# (default is enabled)

chain_hostnames(0);

# the time to wait before a died connection is re-established

# (default is 60)

time_reopen(10);

# the time to wait before an idle destination file is closed

# (default is 60)

time_reap(360);

# the number of lines buffered before written to file

# you might want to increase this if your disk isn't catching with

# all the log messages you get or if you want less disk activity

# (say on a laptop)

# (default is 0)

#sync(0);

# the number of lines fitting in the output queue

log_fifo_size(2048);

# enable or disable directory creation for destination files

create_dirs(yes);

# default owner, group, and permissions for log files

# (defaults are 0, 0, 0600)

# php need to write to yyyyy.info log, so set it to 666

owner(root);

group(root);

perm(0666);

# default owner, group, and permissions for created directories

# (defaults are 0, 0, 0700)

#dir_owner(root);

#dir_group(root);

dir_perm(0755);

# enable or disable DNS usage

# syslog-ng blocks on DNS queries, so enabling DNS may lead to

# a Denial of Service attack

# (default is yes)

use_dns(no);

# maximum length of message in bytes

# this is only limited by the program listening on the /dev/log Unix

# socket, glibc can handle arbitrary length log messages, but -- for

# example -- syslogd accepts only 1024 bytes

# (default is 2048)

#log_msg_size(2048);

#Disable statistic log messages.

stats_freq(0);
