Get different element between 2 sources with join or other command?

Path Finder

Hi guys,

I have 2 sources, historical and current, i need to catch the new events in my monitor, so i compare current with historical, i cant match the persistents events but no the new

Any help with join o command that can do this?

Thanks, Buscatrufas.

Assuming there is some kind of identifier, you could do this:

index=foo (source=historical OR source=new) | stats values(source) as sources by identifier | search NOT sources=historical

That would give you a list of identifiers that are present in the new source, but weren't present in the historical source.
This search is fairly generic, if you want more specific help you'll have to provide more specific details about your events.

Try something this. This should return everything from new, that does not have a corresponding "matchingfield" in historical

index=new NOT [ search index=historical | table matchingfield]
