Splunk SPLK-1001 Exam

The search query index=myindex source=c: \mydata. txt NOT error=* specifies three criteria for the events to be returned:

The index must be myindex, which is a user-defined index that contains the data from a specific source or sources.

The source must be c: \mydata. txt, which is the name of the file or directory where the data came from.

The error field must not exist in the events, which is indicated by the NOT operator and the wildcard character (*).

The NOT operator negates the following expression, which means that it returns the events that do not match the expression. The wildcard character () matches any value, including an empty value or a null value. Therefore, the expression NOT error=means that the events must not have an error field at all, regardless of its value.

The search query does not use quotation marks around the source value, which means that it is case-sensitive and exact. If there are any variations in the source name, such as capitalization or spacing, they will not match the query.

Basic searches and search results

The best description of Splunk Apps is a collection of files that provide specific functionality or views of your data. Splunk Apps can be built by anyone, not only by Splunk employees. Splunk Apps are not only available for download on Splunkbase, but also can be created or customized by users. Splunk Apps are not available on iOS and Android, but rather on Splunk Enterprise or Splunk Cloud platforms.

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.

Splunk alerts are based on searches that run on a schedule or in real time. You can use alerts to monitor for and respond to specific events or conditions in your dat

a. Alerts use a saved search to look for events in real time or on a schedule. Alerts trigger when search results meet specific conditions.You can use alert actions to respond when alerts trigger, such as sending an email, running a script, or creating a ticket1.

You can create alerts from the Search app, the Alerts page, or the Dashboards app.You can also use the Splunk Web framework to create custom alert actions using Python or JavaScript1.

Dashboards, webhooks, and reports are not the basis for Splunk alerts, although they can be related to them. Dashboards are collections of views that display data visually in a variety of ways.You can add alert panels to dashboards to show the status of your alerts2. Webhooks are a type of alert action that send HTTP POST requests to a specified URL when an alert triggers.You can use webhooks to integrate Splunk alerts with external systems or applications3. Reports are saved searches that include additional attributes such as a visualization type, permissions, and an optional description. You can create reports from search results and add them to dashboards as panels. You can also use reports as the basis for scheduled or real-time alerts.
