Hello,

I have a event called "size" and the value be like "125433 Bytes" in log stash. I have few questions here.

1. Can we trim the value as 125433 and use in Visualization ? If so how can we do?
2. Can we convert the value into KB ? If so how can we do?

Please provide me the solution.

Thanks in advance.

Regards,  
Saj
