Splunk SPLK-1004 Dumps Questions Answers

In Splunk, when a user accesses a dataset in Pivot that lacks persistent acceleration, Splunk automatically creates anad hoc data model acceleration. This temporary acceleration is designed to enhance performance during the user's current session.

According to Splunk Documentation:

"Ad hoc summaries are always created in a dispatch directory at the search head."

"These summaries are temporary and exist only for the duration of the user's Pivot session."

This means that the accelerated data model persists only while the user is actively engaged in the Pivot session. Once the session ends, the ad hoc acceleration is discarded.

The tstats command in Splunk is optimized for performance and is typically used with accelerated data models. The summariesonly parameter determines whether the search should use only the summarized (accelerated) data or fall back to raw data if necessary.

Setting summariesonly=false allows the search to use both summarized and raw data, making it suitable for both accelerated and unaccelerated data models.

Setting summariesonly=true restricts the search to only summarized data, which would result in no data returned if the data model is not accelerated.

Therefore, to search an accelerated data model and allow fallback to raw data if needed, the correct query is:

| tstats count from datamodel=acc_datmodel summariesonly=false

The correct search to generate a field with a value of"hello"is:

Copy

1

| makeresults | eval field="hello"

Here’s why this works:

makeresults: This command creates a single event with no fields.

eval: Theevalcommand is used to create or modify fields. In this case, it creates a new field namedfieldand assigns it the value"hello".

Example:

| makeresults

| eval field="hello"

This will produce a result like:

_time field

hello
