[syslog-ng] How to rotate log file in syslog-ng file based on file size

[Balbir Singh]

Dear Team,

I am receiving a log of around 80GB per day.
I want to make a log file of fixed size (suppose 10Gb) and after that file size crossed, new file should be created.


How to do that?




My present configuration is :
------------------------------------




@version:3.2
options {
# sync(0);
# stats (0);
flush_lines(0);
stats_freq(0);
 ts_format(iso);
 keep_hostname(yes);
 log_fifo_size(1024);
};


source s_sys {
 file ("/proc/kmsg" program_override("kernel: "));
 unix-stream ("/dev/log");
 internal();
 udp(ip(0.0.0.0) port(514));
};





destination d_cons { file("/dev/console"); };
#destination d_mesg { file("/home1/log/syslog-ng.log"); };
destination d_mesg {
 file("/home1/asa-log/syslog-ng/$HOST/$YEAR/$MONTH/$DAY/$FACILITY-$HOST-$YEAR-$MONTH-$DAY"
 owner(root) group(root) perm(0600) dir_perm(0700) create_dirs(yes)
 );
};


destination d_auth { file("/var/log/secure"); };
destination d_mail { file("/var/log/maillog" flush_lines(10)); };
destination d_spol { file("/var/log/spooler"); };
destination d_boot { file("/var/log/boot.log"); };
destination d_cron { file("/var/log/cron"); };
destination d_kern { file("/var/log/kern"); };
destination d_mlal { usertty("*"); };


filter f_kernel { facility(kern); };
filter f_default { level(info..emerg) and
 not (facility(mail)
 or facility(authpriv)
 or facility(cron)); };
filter f_auth { facility(authpriv); };
filter f_mail { facility(mail); };
filter f_emergency { level(emerg); };
filter f_news { facility(uucp) or
 (facility(news)
 and level(crit..emerg)); };
filter f_boot { facility(local7); };
filter f_cron { facility(cron); };


#log { source(s_sys); filter(f_kernel); destination(d_cons); };
log { source(s_sys); filter(f_kernel); destination(d_kern); };
log { source(s_sys); filter(f_default); destination(d_mesg); };
log { source(s_sys); filter(f_auth); destination(d_auth); };
log { source(s_sys); filter(f_mail); destination(d_mail); };
log { source(s_sys); filter(f_emergency); destination(d_mlal); };
log { source(s_sys); filter(f_news); destination(d_spol); };
log { source(s_sys); filter(f_boot); destination(d_boot); };
log { source(s_sys); filter(f_cron); destination(d_cron); };
