I’m using ELK for centralized logging
There is one field in my logs that needs to be decoded from base64 and then converted to ucs-2be
How can I do that?
If you want Logstash to output a string in UCS-2BE that's typically done via the codec in the output plugin, but whether this actually makes sense depends on the output plugin(s) you use.
I need to output only one field from strings of my logfile in UCS-2be, not all of them
If you want help please be very explicit in what you want. Which output plugin(s) are you using? Exactly what do you expect it to do?
