Trying to Pick domainType and domainName from below log using the below regex:
It works in regex101 but not in Splunk, it gives a blank column.
domainName - rex"(?:domainName\\\"\:\\\")(?<domainName>([a-zA-Z0-9-\.]+))"
domainType - rex"(?:domainType\\\"\:\\\")(?<domainType>\w)"
"payload":"{\"domainType\":\"L\",\"modifiedBy\":\"\",\"relayHost\":\"\",\"rewriteDomain\":\"\",\"wildcardAccount\":\"\",\"domainName\":\"xxx.yyyyy.com\"}"},"encoding":null,"contentType":"application/json","responseCode":null}
Rex in splunk requires more escaping for backslashes than regex101
| makeresults | eval _raw="\"payload\":\"{\\\"domainType\\\":\\\"L\\\",\\\"modifiedBy\\\":\\\"\\\",\\\"relayHost\\\":\\\"\\\",\\\"rewriteDomain\\\":\\\"\\\",\\\"wildcardAccount\\\":\\\"\\\",\\\"domainName\\\":\\\"xxx.yyyyy.com\\\"}\"},\"encoding\":null,\"contentType\":\"application/json\",\"responseCode\":null} "
| rex "(?:domainName\\\\\"\:\\\\\")(?<domainName>([a-zA-Z0-9-\.]+))"
| rex "(?:domainType\\\\\"\:\\\\\")(?<domainType>\w)"
Below may help you..
|makeresults | eval _raw="\"payload\":\"{\\\"domainType\\\":\\\"L\\\",\\\"modifiedBy\\\":\\\"\\\",\\\"relayHost\\\":\\\"\\\",\\\"rewriteDomain\\\":\\\"\\\",\\\"wildcardAccount\\\":\\\"\\\",\\\"domainName\\\":\\\"xxx.yyyyy.com\\\"}\"},\"encoding\":null,\"contentType\":\"application/json\",\"responseCode\":null}\"" | rex field=_raw "domainType\\\\\":\\\\\"(?<domainType>[^\\\\\"]+).+domainName\\\\\":\\\\\"(?<domainname>[^\\\\\"]+)"

Thanks!! that's worked. 🙂
Hi @Deprasad,
please try this:
| rex "domainType\":\"(?<domainType>[^\"]*).*domainName\":\"(?<domainName>[^\"]*)"

Ciao.

Thanks!! The payload you used in the regex101 is not same as the provided.
Though it worked in Regex101, still faced the same issue with Splunk. Tried the solution suggested by @ITWhisperer and it worked.
