# # 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) #owner(root); group(adm); perm(0640);
# 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);
