Extracting from multiple fields and group by Domain name

[thiagarajan]

My logs looks like this

The regex for timedoutservice is -> (?i)^(?:[^:]*:){5}(?P<timedoutservice>[^\s]+)
Search query is -> sourcetype="MyLog" ("transaction timed out for Service:" MyTest) |stats count as errorcount by timedoutservice

I am getting result something similar to this

timedoutservice                         errorcount
WorkspaceData                               2
MyList                                      1
MyConnnect                                  2

Expected result

timedoutservice                        errorcount        Domain
WorkspaceData                               2            SpaceK
MyList                                      1            SpaceH
MyConnnect                                  2            SpaceL

UUID and Backend will be changing but the domain name remains same for all the services.
The regex for domainName is -> (?i)\tDomain:(?P<Domain>.+)

I just tried to combine both the results

((?i)^(?:[^:]*:){5}(?P<timedoutservice>[^\s]+)(?i)\tDomain:(?P<Domain>.+))

I am getting the exception "Invalid regex: no named extraction at position 0 (i.e., "((?i)^(?:[..."). Expected "(?Ppattern)"
Do i need to use group by. How to extract from multiple fields. Any help is appreciated.

This is what I expected. Thank you very much for the quick reply. Can you explain why I am able get the host name without group by.

The field

domain:value

Should be extracted automatically.

If it is not, have you tried the automated field extraction wizard? (down arrow key next to the event in a regular search)

If it is, then something like this should work:

sourcetype="MyLog" ("transaction timed out for Service:" MyTest) |stats count as errorcount by timedoutservice,domain

This is what I expected. Thank you for the quick reply. But can u tell how I am getting the domain name without any group by. Is it because domain name is unique.
