REX

Hello,  I'm not so good with REX formula, if someone can help me and give me some tip for next time, I appreciate, thanks.

I need to extract the balance (50446.50), the info is in field1

'Col1' Endpoint[442] 'DO' Wallet[501] 'Trilogy' Balance '50446.50 USD'

Try this run anywhere example which shows your data and the necessary rex

| makeresults
| eval field1="'Col1' Endpoint[442] 'DO' Wallet[501] 'Trilogy' Balance '50446.50 USD'"
| rex field=field1 "Balance\s'(?<Balance>[\d\.]+)"

 Hope this helps

Yes, that work for me, if I want to have the "USD" in my results, what I need to change or include?

You can either extract the currency as a separate field, like this

| makeresults
| eval field1="'Col1' Endpoint[442] 'DO' Wallet[501] 'Trilogy' Balance '50446.50 USD'"
| rex field=field1 "Balance\s'(?<Balance>[\d\.]+)\s(?<Currency>\w+)"
| eval Amount=Balance." ".Currency

and then you have Balance and Currency, which you can then join together again if you need, or you can extract it as part of the original Balance field like this

| rex field=field1 "Balance\s'(?<Balance>[\d\.]+\s\w+)"

The benefit of using the former approach is you can then use the numeric balance field if you want to make calculations, whereas with the currency as part of the field, you cannot.
