Event count mismatch when using using `field_name="*"` and `field_name!=""` in tstats query

jshah24 — Mon, 02 Jul 2018 14:03:17 GMT

Why is there a difference between the number of events scanned in both these queries?
Using below query getting statistics count 25 and number of events (Events label below search query) as 214.

| tstats values(XXXX.product_name) as "Product Name" from datamodel=XXXX where (XXXX.threat_name="*") by XXXX.threat_name

But, Using

| tstats values(XXXX.product_name) as "Product Name" from datamodel=XXXX where (XXXX.threat_name!="") by XXXX.threat_name

getting statistics count same 25 and number of events (Events label below search query) as 5,468.

A few things to check here:

you are using summareisonly in the tstats search, are the DMA searches running and summaries are available?
compare apples with apples, use your base search from the data model with your get-_index search
talking of base search: does it return the expected results?
Knowledge objects available to the DMA searches?
permissions?

Just a starting point, but good to check ...

cheers, MuS

1) Are you running for a fixed time frame, such as earliest=-1d@d latest=@d?

2) Compare the output. Which threat_name are the events missing from?

Thanks for the answer MuS.
I have updated the question as per my research and found the problem in this scenario.
