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 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.

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.
