+==== rsyslog: custom log file ====
+Add something like this into a ''/etc/rsyslog.d/myprogram.conf'' file:
+<code># Separate myprogram logging into its own file
+if $programname == 'myprogram' then /var/log/myprogram.log
+& stop</code>
+... then, something like ''logger -t myprogram "this is a log message"'' will get routed to the custom log file. \\
+PHP code to do the same:<code>
+   openlog( "myprogram", 0, LOG_LOCAL6);
+   syslog( LOG_NOTICE, "this is a log message");
+</code>
+Also, don't forget to add the custom log to ''logrotate'' by populating a file like ''/etc/logrotate.d/myprogram'' with:<code>
+/var/log/myprogram.log {
+   missingok
+   weekly
+   size 2G
+   copytruncate
+   rotate 12
+   notifempty
+}</code>
