Pass the Splunk Splunk Core Certified User SPLK-1001 Questions and answers with CertsForce

 The difference between real-time and relative time ranges in the time picker is that real-time searches display results from a rolling time window, such as the last 15 minutes, while relative searches display results from a set length of time, such as yesterday or last week. Real-time searches do not happen instantly, but rather update periodically based on the refresh interval. Relative searches do not happen at a scheduled time, but rather when the user runs them. Real-time searches do not run constantly in the background, but rather when the user starts them. Real-time searches do not represent events that have happened in a set time window, but rather events that are happening now.

The search query sourcetype=access_combined would return events from the access_combined sourcetype, which is a predefined sourcetype in Splunk that matches the access-common or access-combined Apache logging formats1. The sourcetype field is case-sensitive, so using different capitalization such as Access_Combined or ACCESS_COMBINED would not match the exact sourcetype name2. The sourcetype field is also a default field that is added by the indexer when it indexes the data, so it does not need to be enclosed in quotation marks3.

Basic searches and search results

This means that you can use the index field to filter your search results by the name of the index that contains the events you want to see.

For example, if you want to search for events in the index named “gcp_logs”, you can use the following SPL:

index=gcp_logs

You can also specify multiple indexes by using the OR operator, such as:

index=gcp_logs OR index=oswin

This is the appropriately formatted SPL search because it follows the SPL syntax rules12, such as:

Using the = operator to specify field-value pairs, such as index=security and sourcetype=linux.

Using the OR operator to combine multiple values for the same field, such as (invalid OR failed).

Using the | character to separate commands, such as stats count as "Potential Issues".

Using the as keyword to rename fields, such as count as "Potential Issues".
