According to the Splunk documentation, dashboards are collections of views that you can use to visually analyze your dat a. You can create dashboards using simple XML, or use the Splunk Web framework to build custom dashboards using HTML, CSS, and JavaScript.
Dashboards consist of one or more panels that display data in a variety of ways. You can use charts, tables, maps, single value indicators, and other visualizations to display your data. You can also add interactive elements to your dashboards, such as filters, drilldowns, and time range pickers, to make them more dynamic and user-friendly.
To create a dashboard panel from a search result, you can use the Save As button in the Search app and select Dashboard Panel. This will open a dialog box where you can choose an existing dashboard or create a new one, and specify the panel title and visualization type. You can also edit the panel properties and permissions before saving it to the dashboard.
Alternatively, you can create a report from a search result and then add it to a dashboard as a panel. Reports are saved searches that include additional attributes such as a visualization type, permissions, and an optional description. You can create reports using the Save As button in the Search app and select Report. To add a report to a dashboard, you can use the Add to Dashboard button in the Reports listing page or in the report itself.
Dashboards must have a unique dashboard ID within a permission's context. This means that you cannot have two dashboards with the same ID in the same app or user space. The dashboard ID is used to reference the dashboard in URLs and XML files. You can specify the dashboard ID when you create a new dashboard using simple XML or the Splunk Web framework. If you do not specify an ID, Splunk software will generate one based on the dashboard title.

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 stats command calculates statistics based on fields in the events. The count function counts the number of events that match the criteria. The syntax is stats count (field_name), where field_name is the name of the field that contains the value to be counted. In this case, vendor_action is the field name, so stats count (vendor_action) is the correct syntax. Reference: Splunk Core User Certification Exam Study Guide, page 23.
