How to Combine Two Regex to Form One Variable

Hi all,

I have events similar to these:

[10-10-16 18:29:20:057]::TrxThread(A2571700)::DTRACE: Lock acquired for 1000000001
[10-10-16 18:29:20:054]::TrxThread(A2571700)::DTRACE: Lock freed for 1000000001
[10-10-16 18:29:20:057]::TrxThread(A2571700)::DTRACE: Lock acquired for 1000000002
[10-10-16 18:29:20:054]::TrxThread(A2571700)::DTRACE: Lock freed for 1000000002

My objective is to extract TrxThread and subsNumber (ex. 1000000001) and combine them into one variable so that I could differentiate each transaction even though they have the same TrxThread

My end goal is to measure the duration so I'll be using the search below once I get the combined transaction thread and subs number
| stats earliest(_time) as start latest(_time) as end by combined_trx_id | eval dur=end-start

Thanks in advance!

Kindest regards,
Jeff
