That's why I was using tail command to read log tail -n1500 /MarkLogic-Data/Logs/ErrorLog.txt > ~/prodmlerrors.txt But now we don't have access to PROD box so below URL works but not readable, want to know how to spit my error log after a certain size. Can we do some setting change in ML so that it will create a new log after 50 MB. ~Gurbeer From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Danny Sokolsky Sent: Wednesday, April 24, 2013 5:01 PM To: MarkLogic Developer Discussion Subject: Re: [MarkLogic Dev General] Log File Have you tried looking at what the Admin Interface does on /error-logs.xqy ?

I was wondering if I can design a UI where I can see Error log files like this.
