Splunk Search

Which lookups are being used by ES?

Motivator

When looking at the set of lookups available for ES I see more than three hundreds of them. Which lookups are being used by ES and where is it documented?

There are many that are TA based, such as Splunk_TA_cisco-asa and Splunk_TA_bluecoat-proxysg. I assume they are being used to prepare the data for ES but not used directly by ES.

I see only six lookups which were created by ES, such as es_instrumentation_actions.csv and es_instrumentation_datamodels.csv.

While it is documented (in different places that may not make a lot of sense), I would be more interested in the reason why you are asking this question? Do you think that ES lookups are breaking something in search? Are you just curious how ES works?

Why are you asking this question? If you can answer this, you might get more informative answers.

@jnudell_2 - I'm asking because I'm trying to understand ES.

It's interesting to see, for example, under security domains > endpoint > malware center, the New Infections panel which invokes a dynamic lookup -

| from inputlookup:malware_tracker | `dayDiff(firstTime)`

I agree this could be better documented, but the answer is "it depends".

While there are a number of automatic lookups in ES, which other lookups are used depends on which correlation searches you run.

Hi,

the lookups are actually documented. The lookups you were talking about (from TAs) don't have anything to do with ES, as you guessed correctly. Here is a link to the docs: Manage internal lookups

Great, but the link appears to be broken.
