When creating an event type, which is allowed in the search string?
When creating an event type in Splunk, subsearches are allowed in the search string. Subsearches enable users to perform a secondary search whose results are used as input for the main search. This functionality is useful for more complex event type definitions that require additional filtering or criteria based on another search.

When using the timechart command, what optional argument is used to specify the interval of _time?
Comprehensive and Detailed Step-by-Step
The timechart command in Splunk is used to generate time-series visualizations of data.
The span argument is used to specify the interval (or bin size) for the _time field.
Example usage:
css
CopyEdit
index=_internal | timechart span=1h count
This command will create a timechart where _time is grouped into 1-hour intervals.
bin is used in the bin command to group numerical or time-based fields but is not specific to timechart.
by is used to split results by a specific field but does not define the interval.
over is not a valid argument for timechart.

Given the following eval statement:
... | eval field1 = if(isnotnull(field1),field1,0), field2 = if(isnull(field2), "NO-VALUE", field2)
Which of the following is the equivalent using fillnull?
The fillnull command can be used to replace null values in specific fields. The correct equivalent expression for the given eval statement would involve using fillnull twice, once for field1 to replace null values with 0, and once for field2 to replace null values with 'NO-VALUE'.
