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 data. 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.

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".

The Power role contains the minimum permissions required to have write access to Splunk alerts. The User role can only view alerts created by others, but cannot create or modify them. The Alerting role is not a default role in Splunk, but a custom one that can be created by an administrator. The Admin role has write access to Splunk alerts, but also has many other permissions that are not necessary for alerting3.
