Query data on a dashboard
You can specify a query time range for a dashboard. After you specify the query time range, all charts on the dashboard display the query and analysis results based on the same time range.
The specified query time range is only for temporary use. Simple Log Service does not save the settings. The next time you open the dashboard, Simple Log Service displays query and analysis results based on the default time range.
Specify a query time range
In the top navigation bar of the dashboard page, click Select Time Range to specify a query time range. After you specify the query time range, you can move the pointer over the time that is displayed to view the specific time range.
Time range
Description
Relative time range
Queries log data generated in a time range that ends with the current time, such as the previous 1 minute, 5 minutes, or 15 minutes. For example, if the current time is 19:20:31 and 1 Hour is selected as the relative time range, the charts on the dashboard display the log data that is generated from 18:20:31 to 19:20:31.
Time frame
Queries log data generated in a time range that starts and ends on the minute or hour. For example, if the current time is 19:20:31 and 1 Hour is selected as the time frame, the charts on the dashboard display the log data that is generated from 18:00:00 to 19:00:00.
Custom time range
Queries log data that is generated within a time range that you specify.
View data that meets filter conditions on a dashboard
In the top navigation bar of the dashboard page, click Select Time Range to specify a query time range. Then, click the Filter icon of the dashboard to add filter conditions. This way, the system queries the log data that is generated within the specified time range and meets the specified filter conditions. For example, the current date is September 6, 2024, Yesterday(Relative) is specified for the Select Time Range parameter,
GET
is selected for themethod
filter, and200
is selected for thestatus
