How to get results only from the last source file?

[bruno_eduardo]

Hi,

I got an index which continuously receive new source file automatically, what I want is to my search to only return events from the last source file. Should be something simple but I did not figure it out, maybe with the |head command.

Like this (replace ... with the exact same base search; yes, twice):

... [ ... | stats latest(source) AS source ]

Yes!! In my case I have solved with head comand:

index=index1 source="file.csv" Status="Active" [search index=index1 source="file.csv" | dedup _time | head 1 | return _time] |...

What about the Before Last?

[woodcock]

Like this:

... NOT [ ... | stats latest(source) AS source ]

[bruno_eduardo]

But I mean before last source file only

[woodcock]

Did you try it? That's what it does.

[bruno_eduardo]

Yes I tried, I have 20 source files for this index and when I do this I got 19, every each of them except the last one. What I need is only the 19th one. I already got the 20th with your answer, just need the before last.

Like this:

... [ ... | dedup source | reverse | list(source) AS source| eval source=mvindex(source,1) ]

You can then adjust the 1 to whichever one you would like.

That is really great but don't solve the problem, This search would only help if I had a fixed number of source files, the problems is: The index continuously receive new source file automatically, so I would need to change the search every time.

Sorry it worked, without the |reverse, look:

index="myindex" [search index="myindex" | dedup source |stats list(source) AS source| eval source=mvindex(source,2) ]

this bring myu before last source file events.

Thanks
