質問 # 16
Which of the following elements sets a token value of sourcetype=access_combined?
A. <set token="NewToken">sourcetype=$click.value$</set>
B. <set token="NewToken" prefix="sourcetype=">$click.value$</set>
C. <set token="NewToken">sourcetype=$click.value$</set>
D. <set token="NewToken"> prefix="sourcetype=">$click.value$</set>
正解：B
解説：
In Splunk, tokens are used in dashboards to dynamically pass values between different components, such as dropdowns, text inputs, or clickable elements. The<set>tag is a Simple XML element that allows you to define or modify the value of a token. When setting a token value, you can use attributes likeprefixandsuffix to construct the desired value format.
Question Analysis:
The goal is to set a token namedNewTokenwith the valuesourcetype=access_combined. This requires constructing the token value by combining a static prefix (sourcetype=) with a dynamic value (e.g.,$click.
value$, which represents the value clicked or selected by the user).
Why Option D Is Correct:
Theprefixattribute in the<set>tag allows you to prepend a static string to the dynamic value. In this case:
* Theprefix="sourcetype="ensures that the token starts with the stringsourcetype=.
* The$click.value$dynamically appends the selected or clicked value to the token.
For example, if$click.value$isaccess_combined, the resulting token value will be sourcetype=access_combined.
Example Use Case:
Suppose you have a dashboard with a clickable chart where users can select a sourcetype. You want to set a token (NewToken) to capture the selected sourcetype in the formatsourcetype=<selected_value>. The following XML snippet demonstrates how this works:
<dashboard>
<row>
<panel>
<html>
<a href="#">Set Token</a>
</html>
</panel>
</row>
<row>
<panel>
<table>
<search>
<query>index=_internal $NewToken$ | stats count by sourcetype</query>
</search>
</table>
</panel>
</row>
</dashboard>
In this example:
* Clicking the link triggers the<set>logic.
* The tokenNewTokenis set tosourcetype=access_combined.
* The search query uses$NewToken$to filter results based on the selected sourcetype.

By using theprefixattribute correctly, Option D ensures that the token value is constructed in the desired format (sourcetype=access_combined), making it the verified and correct answer.

Which of the following functions' primary purpose is to convert epoch time to a string format?
A. tonumber
B. strptime
C. tostring
D. strftime
正解：D
解説：
The strftime function in Splunk is used to convert epoch time into a human-readable string format. It takes an epoch time value and a format string as arguments and returns the time as a formatted string. Other options, like strptime, convert string representations of time into epoch format, while tostring converts values to strings, and tonumber converts values to numbers.

Which statement about tsidx files is accurate?
A. Splunk removes outdated tsidx files every 5 minutes.
B. Each bucket in each index may contain only one tsidx file.
C. A tsidx file consists of a lexicon and a posting list.
D. Splunk updates tsidx files every 30 minutes.
正解：C
解説：
A tsidx file in Splunk is an index file that contains indexed data, and it consists of two main parts: alexicon and a posting list (Option C). The lexicon is a list of unique terms found in the data, and the posting list is a list of references to the occurrences of these terms in the indexed data. This structure allows Splunk to efficiently search and retrieve data based on search terms.
