Here is a way to get the last 5000 characters from a log by first asking for
the size of the file, then taking a substring:
xquery version "1.0-ml";
let $length := xdmp:filesystem-file-length("c:/Program
Files/MarkLogic/Data/Logs/ErrorLog.txt")
return
fn:substring-after(
fn:substring(
xdmp:filesystem-file("c:/Program Files/MarkLogic/Data/Logs/ErrorLog.txt"),
$length - 5000, $length) ,
"
")

Thanks , below is the one I was looking for
Another question , how to shorten my Errorlog.txt
Currently they are so big (>500MB) I can't open them in browser.
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.

Have you tried looking at what the Admin Interface does on /error-logs.xqy ?
For example:
http://localhost:8001/error-logs.xqy

We have log file sitting under folder
/MarkLogic-Data/Logs/ErrorLog.txt
As per firm policy, developer has no access to PROD box. I was wondering if I
can design a UI where I can see Error log files like this.
I want to write on XQY which will read above path and list all files in that
folder

Also let me know how to split my log file they are of approx 500 MB
They are with the default setting
System log file: notice
File log level: info
Rotate log file: daily
Keep log file: 7
