[Mutate update](https://www.elastic.co/guide/en/logstash/current/plugins-filters-mutate.html#plugins-filters-mutate-update) to update value or rename to change the field name.

</div>

Something like this:  
`mutate { gsub => ["[nginx][access][uripath]","\/server\/oauth2\/userinfo\/slaves\/*", "/server/oauth2/userinfo" ] }`  
Is this part in url? For instance, /server/oauth2/userinfo/slaves/images/pic.jpg?
