View traces

The Traces tab displays up to 100 traces that consume the most amount of time on the specified host within the specified period of time.

Note

In the Status column, the green icon indicates that the time consumed is less than 500 milliseconds. The yellow icon indicates that the time consumed ranges from 500 milliseconds to 1,000 milliseconds. The red icon indicates that the time consumed is greater than 1,000 milliseconds or that one of the tag keys of the trace is set to error.

On the Traces tab, you can perform one of the following operations based on your business requirements:

Enter a value that is accurate to milliseconds in the Takes Longer Than (ms) field and click Query. Then, the traces whose time consumed is greater than the specified value are displayed on the Traces tab.
Select Exceptions and click Query. Then, abnormal traces are displayed on the Traces tab.
Click the up or down arrow next to Generation Time or Elapsed Time to sort the traces in descending or ascending order.
Click the ID of a trace to go to the Traces page. The page displays the waterfall chart of the trace.
