Dashboard filters enable you to focus on the information you want to explore. All dashboards have the following filters:
Time Filter: Enables you to select a historical time period, such as last 24 hours, last 7 days, last 30 days, and last year.
Filters: Enables you to set a wide range of filters by selecting parameters, such as Application is MyApp or by clicking on a specific data point in a dashboard panel
Search: Enables queries that use logical operators, such as AND, OR and NOT between fields, such as JobName:job* AND Application:App1 or Application:App2
After you achieved the desired view using filters, you can click Saved Queries and designate a name, allowing you to quickly return the view later.
