By using the trace query function, you can view the status of the invocation trace in the system, especially for tasks that are slow or have encountered an error.
Log on to the EDAS console and Select Microservice Management > Trace Query in the left-side navigation pane.
Click Show Advanced Options in the upper-right corner of the Trace Query page to display more query conditions.
Specify the query conditions and click Query.
The descriptions for the parameters of the invocation traces (advanced query conditions) are as follows:
Time range: Click the time selector, set the query start time, and then select the end time. The options for the end time are “This Second”, “To 1 Minutes Later”, and “To 10 Minutes Later”. Therefore, the latest time periods are: last second, last one minute, and last ten minutes.
Application name: Select an application from the drop-down list. You can also enter a keyword to search for an application. Manual input of an application name is not supported.
Call type: Select the call type to query from the drop-down list. Options are HTTP, HSF provider, HSF consumer, MySQL, Redis cache, message sending, and message receiving.
Set the threshold values for time elapsed, request, or response for querying slow tasks in the system.
Select the Error check box in the upper-right corner to query the error cases only.
Specify other parameters as needed.
In the query result, click on a slow or erroneous task to view trace details.
