RegEx How to find two strings from splunk log

I have below log:

Service ABCD(blabla_blabla): 365.45.1.87.3.60354 -> remote.234.5 Failure
Service DERF(blabla_blabla): remote.567.9 -> remote.284.9 Failure

and would like to catch with RegEx:

a: 365.45.1.87.3.60354 b: remote.234.5

a: remote.567.9 b: remote.284.9

Thanks for help

Hi @dabroma5
try this regex:

| rex ":\s+(?<a>[^ ]+)\s+-\>\s+(?<b>[^ ]+)"

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

if eventually you have some false positive, you could also try:

| rex ":\s+(?<a>[^ ]+)\s+-\>\s+(?<b>[^ ]+)\s+Failure"

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

Ciao.
