Hi @aditsss,

please try this:

| rex "\/[^\/]+\/((nifi-api\/flow)|(nifi-api))\/(?<your_field>[^\/]+)"

that you can test at https://regex101.com/r/Fa01uS/2

Ciao.

Hi @aditsss,

if you need to extract the string between "nifi-api/" and the first "/", you could use a regex like this:

| rex "nifi-api\/(?<your_field>[^\/]+)"

Ciao.
