APM Trace

The Trace screen displays details of the error that occurred on an endpoint and the route it took to hop to the endpoint on an instance.

The SixthSense application supports two types of traces:

Success trace: This section displays all the endpoints that were successfully executed.

Error trace: This section displays the path adopted by the endpoint that resulted in an error.

The Trace screen provides the following options. Note that you can use the filter options to sort the data.

Trace window

Go to the Trace tab to analyze the transactions that were successful but were slow. You can sort the response time details by Start time or Duration by clicking on the Sort by: drop-down list.

Instances

The All Instances drop-down list displays the following options:

• All instances: Shows all the instances on which the application is installed.
• Particular instance: Click an instance displayed or search for an instance in the Search instances field to view details of a selected instance.

Error

The All status drop-down list displays the following options:

• All status: Shows all the errors with different statuses.
• Success: Provides further analytics on the successful transaction on that endpoint.
• Error: Shows all the errors occurring on a selected instance.

Endpoints

The All Endpoints drop-down list displays the following options:

• All endpoints: All the endpoints of the application are displayed.
• Particular endpoint: Select an endpoint or search for an endpoint in the Search endpoints field to view details of a particular endpoint. The following screen is displayed.

The Method and Method name columns display methods that are executing as displayed in the following screen. They are based on method-level profiling which helps identify and improve performance of an application. For example, identify methods that are taking a long time to execute.

note

You can view the endpoint details in a list, tree, table or flame view format by clicking on the respective icons in the Trace screen.

The following screen is an example of a flame view.

Downloading the trace report

Selecting the Trace tab and clicking    will download the trace details along with the application name in a PDF format.

Navigating to Trace, selecting Error from the All status drop-down list, and clicking the    will download the Error Trace details and VM details along with the application name in PDF format.

Click the Infrastructure    icon to view the correlated VM details. For more information, see Infrastructure.

Click an endpoint under the Method or Method name column, to view the Span info window with the following details.

Tags	Value
Application:	Application name
Endpoint:	Endpoint that is causing the error.
Span type:	Information about a specific code path that has been executed.
Component:	Specific module in the software code.
Peer:	Details of a peer-to-peer event.
Error:	Specifies the error type.
URL:	Exact URL of the endpoint.
http.method:	API method type.
http.status.code:	Code that identifies the status of an error.
http.status.msg:	Message status.

Downloading the Span info report

Clicking the    will download the span information report in a PDF format as in the following screen.

Logs

Field	Description
Time	Time stamp of the endpoint error.
Event	Type of event.
Error.kind	Details of the endpoint error.
Message	Detailed description of the endpoint error.
Stack	Navigate to the exact line of code.

Error traces

The Error traces screen displays the errors on the left pane which can be sorted by Start time or Duration of the errors. The endpoint error details with the method name, execution time, application name and so on are displayed on the right side for you to analyze the root cause.

Slow traces

The Slow traces screen displays all the endpoints that were slow against the expected load time. Using slow traces details, you can identify the endpoints that caused the slowness. And you can further analyze the root cause for the slowness using method name and execution time.
