Get distinct count from different sources

[raghubankapur]

I have 3 different sources of the same filed. I want to aggregate all the 3 sources and get the distinct count of the field

eg.

sourcetype=source1 | stats dc(userlist)

sourcetype=source2 | stats dc(line.userlist)

sourcetype=source3 | stats dc(line.subject)

Here userlist, line.userlist, line.subject are all the same attributes but being logged differently. Now I want to get the dc of userlist+line.userlist+line.subject. Any help is appreciated.

Assuming that the fields only exist in their respective sourcetypes, you could try something like this

sourcetype=source1 OR sourcetype=source2 OR sourcetype=source3
| eval userlist=coalesce(userlist, line.userlist, line.subject)
| stats dc(userlist)

This works well @ITWhisperer
