Hi @sekhar463

the phrase from @bowesmana means that using the rex command you can extract a field from the entire raw log (without specifying any field) as in your case, or specifying a field.

Ciao.

@sekhar463,

you could try this:

| rex "^([^\|]+\|\s+){2}\[(?<URL>[^\]]+)\]"

that you can test at https://regex101.com/r/2HDtmM/1

Use 

| rex "\[(?<url>http[^\]]*)\]"

assuming you are parsing _raw field

I am assuming your example has 3 rows with 3 urls. The field name extracted above will be url
