remove all text before certain words in events

[trilocho]

I have events like below

-a3bcd: Info1234x:NullValue

-a3bcd: Info1234x:NullValue

-b3bcd: Info1234x:NullValue2

-c3bcd: Info1234x:NullValue3

I managed to produce a table like these

ErrorInfo                                                     Count

a3bcd: Info1234x:NullValue               2

-b3bcd: Info1234x:NullValue2           1

-c3bcd: Info1234x:NullValue3           1

I would like to condense those events into one since they are all same kind of error just different paramter

so it would be like

ErrorInfo                                                     Count

Info1234x:                                                   1

Thanks in advance

| eval ErrorInfo = mvindex(split(ErrorInfo, ":"),1)
