APM Dashboard
Use the application dashboard, to view statistics related to an application you select in the Select application: drop-down list. By default, the Dashboard tab is selected.
Dashboard
The Dashboard screen displays the following options:
Application
The Application screen displays all statistics at the API level that are related to a particular application configured on an instance.
Apdex score
The SixthSense application internally calculates the apdex score based on the performance of the application and displays the health indicator accordingly as in the following screen.
In the Health indicator pane, if you find the Apdex score denoted as Poor, go to the Endpoint by error % and Endpoints by response time(ms) tabs to take remedial action.
The SixthSense application monitors and displays the Apdex score using the following classification:
| Health Indicator Status | Apdex Score Range | Required Action |
|---|---|---|
| Good | 0.84 - 1.0 | Indicates a healthy status. No immediate action required. |
| Fair | 0.69 – 0.83 | See Endpoint by error % and Endpoints by response time(ms) tab in the screen below. |
| Poor | 0.00 – 0.68 | See Endpoint by error % and Endpoints by response time(ms) tab in the screen below. |
You can set the response time threshold value for the apdex score (in milliseconds) using Settings on the left pane. Navigate to Settings > Application > Apdex Configuration and set the value.
You can expand, contract, and reset the view to the default timeline by clicking the icons available on the top right corner of the following Load , Error and Response time widgets. For more information about performing various actions, see Working with a widget.
Load widget
The Load widget is a graphical representation of the number of calls the application is receiving during a particular period similar to the following screen.
Click on any point in the graph to view the number of calls the application has received during the selected time.
Error widget
The Error widget displays a graph of the number of errors encountered by an application in a particular period similar to the following screen.
Click on any point in the graph and you can view the number of errors the application has received at that point in time.
Response time widget
The Response time widget displays the average response time taken by an application in a particular period similar to the following screen.
Click on any point in the graph and you can view the response time of an application at that point in time.
The following widget displays the endpoint and instances by error in % and response time in milli seconds similar to the following screen.
* Endpoint by error %The SixthSense application monitors and displays errors encountered by each application endpoint as in the following screen.
This window displays the top 5 end point errors with percentage in milliseconds. By default, the top 5 endpoints that need your immediate attention are displayed. Click on an endpoint name which will take you to the Endpoint screen. For more information, see Endpoint.
note
Use the copy 
icon to copy the endpoint which you can use to search endpoints in other screens or widgets.
- Instances by error %
The Instances by error% window monitors and displays the errors that are encountered by a particular application instance where the application is installed. Click on an instance name which will take you to the Instance screen. For more information, see Instance.
- Endpoints by response time(ms)
The Endpoints by response time(ms) window monitors and displays the errors that are encountered by a particular endpoint and corresponding response time taken by the endpoint. Click on an endpoint which will take you to the Endpoint screen. For more information, see Endpoint.
- Instances by response time(ms)
The Instances by response time(ms) window monitors and displays the response time taken by an application instance. Click on an instance name which will take you to the Instance screen. For more information, see Instance.
Percentile response time
You can use percentiles to understand your application performance better. In this widget, the response time values range from 0 to 24000 ms and percentiles from 50th percentile to 99th percentile. By default, all the percentile radio buttons are selected. You can select only the required percentile values: for example, P90 is selected in the following screen. You can see the response time taken by an application at 90th percentile and work on improving the application performance if the response time values are high.
Endpoint
The Endpoint screen displays the list of all the application endpoints in an instance. The following information is available on this screen when you navigate to APM > Dashboard > Endpoint.
| Field | Description |
|---|---|
| Name | Endpoint name |
| Error % | Percentage of errors occurring on a particular endpoint. |
| Errors | Number of errors occurring on a particular endpoint. |
| Errors/min | Number of errors per minute. |
| Response time (ms) | Response time taken by the endpoint. |

This widget helps you understand in detail the endpoint errors. If you know the name of the endpoint, enter it in the Search endpoints field or click on an endpoint listed under the Name column.
Viewing diagnostic information to identify endpoint errors
Do any of the following in the Endpoint screen.
a. Enter or paste the name of the endpoint if you have copied the endpoint earlier in the Search endpoints field or
b. Click on an endpoint to view the endpoint dashboard where the Load, Error, Response time, and Percentile response time widgets are displayed.
Click Error Traces in the Error widget to view the list of errors for that endpoint. Complete trace level details are displayed in the Trace window to identify the errors and fix them. For more information about the Error screen, see Error trace.
Click Slow Traces in the Response time widget to view the list of endpoints that are slow. Complete trace level details are displayed in the Trace window to identify the errors and fix them. For more information about the Trace screen, see Slow trace.
Instance
The Instance screen displays details of all the instances on which a particular application is installed. The following information is available on this screen when you navigate to APM > Dashboard > Instance.
