Config file facility:



Detailed logging example for FTP!

Edit file:


Add filter:

filter f_local4debug { level(debug) and facility(local4); };
filter f_local4info  { level(info)  and facility(local4); };
filter f_local4      { facility(local4); };
filter f_ftp_info   { level(debug,info,debug) and facility(ftp); }; 	# To FTP (facilityname=ftp)

destination ftp_info   { file("/var/log/pure-ftpd.log");};
log { source(src); filter(f_ftp_info); destination(ftp_info); };

destination local4debug { file("/var/log/local4.debug"); };
log { source(src); filter(f_local4debug); destination(local4debug); };

destination local4info { file("/var/log/local4.info"); };
log { source(src); filter(f_local4info); destination(local4info); };

destination local4 { file("/var/log/local4"); };
log {source(src); filter(f_local4); destination(local4); };


/etc/syslog-ng/syslog-ng.conf with:
SuSEconfig --module syslog-ng

Usage and test

logger -p local4.info "my message"
logger -p local4.debug "my message"
logger -p local4 "my message"


See logrotate (/etc/logrotate.d/ and /etc/logrotate.conf) for more options/details.

Config examples are in:


Copy existing file to new profilname (e.g.)

cp pure-ftpd new_profile_name

and edit.

Execute manually to activate:

logrotate /etc/logrotate.conf                         #all


logrotate -d /etc/logrotate.d/new_profile_name        #Test "new_profile_name"
logrotate /etc/logrotate.d/new_profile_name           #Rotates "new_profile_name"

Example file:

/var/log/nginx/*.log {
        #monthly                                                                                                                 #rotates once a month
