Math filter plugin

Elastic Stack Logstash
1

Hello! I was searching for ability to perform arithmetic operations in logstash, found old topic about it - Arithmetic Operations in logstash - where where the math plugin was mentioned, but I haven't found any documentation about it. Could you please provide me an example how can I add two fields using that plugin?

Thank you in advance,
Pavlo

Hello,

This filter is a third-party filter that seems to not be maintained anymore, I don't think it even install in newer versions.

You will need to use a ruby filter as mentioned in the same topic you linked.
