How to concat all rows in a single field able and use the result in another "search port IN"

In my Search 1, it will list all unique port numbers associated with a certain IP address, i.e. 1.2.3.4

"MYTOKEN is: fcd4e600-eda2-4ee0-a3b3-093562f49c2e" | rex "1.2.3.4:(?<ipport>.*?) " | dedup ipport | table ipport | table ipport



And then I'd like to concatenate those ports into one long string delimitated with "," that is, "57432, 57453,57198" and finally this concatenated string will be used in another search, i.e 

"https_client-init <HTTP_REQUEST>: " | rex "2.3.4.5:(?<port>.*?) " | search port IN([search "MYTOKEN is: fcd4e600-eda2-4ee0-a3b3-093562f49c2e" | rex "1.2.3.4:(?<ipport>.*?) " | dedup ipport | table ipport | table ipport])

 

It will be really appreciated if someone could shed the light of how it can be solved. thanks in advance!

Hi @vsasdao,

Please try below query;

"https_client-init <HTTP_REQUEST>: " | rex "2.3.4.5:(?<port>.*?) " | search  [search "MYTOKEN is: fcd4e600-eda2-4ee0-a3b3-093562f49c2e" | rex "1.2.3.4:(?<port>.*?) " | dedup port | fields port]

Great!

Subsearches formats the results into a single linear search string. You can this string by running the subsearch by adding "| format" command at the end. I changed field name to port to create suitable search string from subsearch.

You can find more detail in below doc.
