Now let’s begin with some of the best Splunk Core Certified Power User Interview Questions.
1. What is Chart?
The chart command is used as a transforming command that returns your results in a table format. The results can then be used to visualize the data as a chart, such as a column, line, area, or pie chart.
2. List the arguments used in Chart command?
- Firstly, stats-agg-term
- Secondly, sparkline-agg-term
- Lastly, eval-expression
3. What is eval-expression?
An eval-expression is a combination of literals, fields, operators, and functions that represent the value of your destination field.
4. List the Optional arguments?
- Lastly, row-split
5. Mention the Chart options?
- Lastly, Sep
6. Define the Sparkline options?
Sparkline are defined as the inline charts that appear within table cells in search results and display time-based trends associated with the primary key of each row.
7. What is the use of Bin options?
The bin options are use to control the number and size of the bins that the search results are separated, or discretized, into.
8. What are the tc options?
The timechart options are part of the <column-split> argument and control the behavior of splitting search results by a field.
9. What is the most common use of the “where clause option”?
The most common use of the “where clause” option is to select for spikes rather than overall mass of distribution in series selection.
10. Define a Timechart?
A timechart is a statistical aggregation applied to a field to produce a chart, with time used as the X-axis. You can specify a split-by field, where each distinct value of the split-by field becomes a series in the chart.
11. What is the use of eval command?
The eval command calculates an expression and puts the resulting value into a search results field. Moreover, this command is use to evaluates mathematical, string, and boolean expressions.
12. What is the difference between eval and stats commands?
The stats command calculates statistics based on fields in your events. Whereas, the eval command creates new fields in your events by using existing fields and an arbitrary expression.
13. List the Operators that produce numbers?
- The plus ( + ) operator accepts two numbers for addition, or two strings for concatenation.
- Lastly, the subtraction ( – ), multiplication ( * ), division ( / ), and modulus ( % ) operators accept two numbers.
14. Mention the Operators that produce strings?
The period ( . ) operator concatenates both strings and number. Numbers are concatenated in their string represented form.
15. List the Operators that produce booleans?
- The AND, OR, and XOR operators accept two Boolean values.
==operators accept two numbers or two strings.
- In expressions, the single equal sign (
=) is a synonym for the double equal sign (
- The LIKE operator accepts two strings.
16. How to specify a field name with multiple words?
To specify a field name with multiple words, you can either concatenate the words, or use single quotation marks when you specify the name.
17. When are Calculated fields used?
One can use calculated fields to move the commonly used eval statements out of your search string and into props.conf, where they will be processed behind the scenes at search time.
18. Describe the Search command?
The search command is use to retrieve events from indexes or filter the results of a previous search command in the pipeline. You can retrieve events from your indexes, using keywords, quoted phrases, wildcards, and field-value expressions. Moreover, there is no need to specify the search command at the beginning of your search criteria.
19. List the Boolean expression?
- Expressions within parentheses
- NOT clauses
- OR clauses
- AND clauses
20. List some examples of search terms?
- quoted phrases
- boolean operators
- Lastly, field-value pairs.
21. What is the use of backslash character?
The backslash character is used to escape quotes, pipes, and itself. Backslash escape sequences are still expanded inside quotation marks.
22. Explain fillnull?
Null values are field values that are missing in a particular result but present in another result. Use the fillnull command to replace null field values with a string.
23. What do you understand by transaction?
The transaction command finds transactions based on events that meet various constraints. Moreover, transactions are made up of the raw text of each member, the time and date fields of the earliest member, as well as the union of all other fields of each member.
24. List the two raw events added to the transaction?
- Firstly, Duration
- Lastly, Eventcount
25. What is the difference between duration and eventcount?
The values in the duration field show the difference between the timestamps for the first and last events in the transaction. Whereas, the values in the eventcount field show the number of events in the transaction.
26. Define an event?
An event is not the same thing as an event type. An event is a single instance of data a single log entry, for example. Moreover, an event type is a classification used to label and group events.
27. List the three post-search entry points to the field extractor?
- Firstly, Bottom of the fields sidebar
- Secondly, All Fields dialog box
- Lastly, Any event in the search results
28. What are Field aliases?
Field aliases are an alternate name that is assigned to a field. One can use that alternate name to search for events that contain that field. A field can have multiple aliases, but a single alias can only apply to one field.
29. How to create calculated fields with Splunk Web?
- Select Settings > Fields.
- On the row for Calculated Fields, click Add new.
- Select the Destination app that will use the calculated field.
- Select a host, source, or source type to apply to the calculated field. Provide the name of the host, source, or source type.
- Name the resultant calculated field.
- Provide the eval expression used by the calculated field,
30. How to add tags to event types using Splunk Web?
- Navigate to Settings > Event types.
- Locate the event type you want to tag and click on its name to go to its detail page.
- On the detail page for the event type, add or edit tags in the Tags field.
- Click Save to confirm your changes.
31. Define search macros in Settings?
Search macros are reusable chunks of Search Processing Language (SPL) that can insert into other searches. Search macros can be any part of a search, such as an eval statement or search term, and do not need to be a complete command.
32. List some of the shortcuts to Check the contents of your search macro from the Search bar?
- Command-Shift-E (Mac OSX)
- Control-Shift-E (Linux or Windows)
33. What is the use of workflow actions in Splunk Web?
It enable a wide variety of interactions between indexed or extracted fields and other web resources with workflow actions. Workflow actions have a wide variety of applications.
34. Define Filters?
Filters restrict the events that will be processed by the pivot. They are added by invoking either the addFilter() or addLimitFilter() method.
35. What are Row splits?
Row splits divide the data in a pivot table into rows before aggregates are calculated for each cell.
36. What do you understand by Column splits?
Column splits are the complement to row splits. They divide events that pass through the filters into sets before aggregates are calculated for each cell.
37. Expand and explain CIM?
The CIM stands for Common Information Model (CIM). It is a shared semantic model focused on extracting value from data. The CIM is implemented as an add-on that contains a collection of data models, documentation, and tools that support the consistent, normalized treatment of data for maximum efficiency at search time.
38. What is a data model?
A data model is a hierarchically structured search-time mapping of semantic knowledge about one or more datasets. It encodes the domain knowledge necessary to build a variety of specialized searches of those datasets. These specialized searches are used by Splunk software to generate reports for Pivot users.
39. Define Estimation?
The process of agreeing on a size measurement for the stories or tasks in a product backlog. On agile projects, estimation is done by the team responsible for delivering the work, usually using a planning game or planning poker.
40. How to add tags to a event type?
- In Splunk Web, click Settings > Event types.
- Locate the event type that you want to tag and click its name.
- On the detail page for the event type, add or edit tags in the Tags field. Separate tags with spaces or commas.
- Click Save.
