Hi,
I’ve tried to setup my RB1100 to log to MicroSD-Card.
When I follow http://wiki.mikrotik.com/wiki/Manual:System/Log I cannot run “/system logging action=file” this results in “expected command name” error 
Am I doing something wrong?I have RouterOS 5.20
Are you trying to just print a current log to file or trying to track something?
try
/log print file=filename
I’m trying to set the logging to save on SD-card and not in memory
Try
/system logging action add name=microSD target=disk disk-file-name=<directory of microSD>/log
the directory should be visible under /file print
a good example with a USB drive would be something to the effect of
disk-file-name=usb1/log
That worked - thanks!
