Mask or remove specific words from log line #828

Closed router19 closed 2 weeks ago

router19 commented 1 month ago

Hi I have a requirement wherein I would want to match a specific regex and dont allow words matching such regex to be logged.

I explored logback matcher but it removed the complete formated message. I need only a specific word matching regex in the formatted message to be removed or replaced with some characters say *

Example

Formatted message : I love logback library as it is best.

Ouput I want if logback matches the regex : I love library as it is best Or I love *** library as it is best

Hi Vinit,

Logback comes with the replace conversion word which corresponds to your requirements.

Thank you for your response. Will that impact performance of the application as each log line will be matched against the regex.

Yes, there will be some a performance impact. However, I have not tested the extent of the impact.

Added LOGBACK-1770 for tracking this issue.

Fixed in commit e7d945906d3b156 which introduces %maskedKvp converter.
