Viewing Bucket Logs¶
AOM supports fine-grained log query. That is, you can view logs by bucket to obtain key service data and quickly locate problems.
Precautions¶
Before viewing bucket logs, ensure that you have created at least one log bucket. Otherwise, you cannot view bucket logs.
You can view bucket logs generated in the last seven days.
Viewing Bucket Logs¶
Log in to the AOM console. In the navigation pane, choose Log > Log Buckets, and click the Bucket Log tab to view logs.
Set filter criteria.
Select a log bucket: Select a target log bucket from the drop-down list in the upper left corner.
Set a time range: In the drop-down list in the upper right corner, select a time range, such as Last 30 minutes, Last 1 hour, or Last 6 hours. You can also select Custom time range to specify the start time and end time.
Enter a keyword: Click the text box. All statistical rules and keywords of the bucket are displayed under the text box. Select a keyword. It is automatically displayed in the text box. Alternatively, enter a keyword directly in the text box.

Viewing statistical data in a bar chart
The bar chart shows the number of logs that met the filter criteria set in step 2 in different time periods. The horizontal axis represents the time and is divided into 30 rectangular blocks of the same size. The time duration indicated by each rectangle block is selected time range/30. For example, if the time range is 30 minutes, the time duration of each rectangle block is 1 minute. If the time range is set to 60 minutes, the time duration of each rectangle block is 2 minutes. The vertical axis represents the number of queried logs.
