Analyzing Statistics for Messages

This section explains how to view and analyze statistics relating to WSO2 EI messages using WSO2 Analytics.

Use one of the following methods to view information in this page.

When you open the EI Analytics dashboard, the Overview page is displayed by default. Click on the proxy service/REST API/sequence/endpoint/inbound endpoint with the message you want to view in the relevant gadget. Then click on the required message ID in the MESSAGES gadget.
Open any of the following pages by clicking on the relevant link in the left navigator and search for the proxy service/REST API/sequence/endpoint/inbound endpoint with the message you want to view. Then click on the required message ID in the MESSAGES gadget.
- OVERVIEW/PROXY
- OVERVIEW/API
- OVERVIEW/SEQUENCES
- OVERVIEW/ENDPOINT
- OVERVIEW/INBOUNDENDPOINT

At any given time, this page displays the statistics for a selected time interval. Make sure you select the required time interval in the following bar displayed at the top of the page. If you want to define a custom time interval, click Custom and select the start and end dates of the required time interval in the calendar that appears.

Message Flow

View (Example)
Description	This indicates the proxy service that processed a selected message and the mediators that were used to process the message.
Purpose	If a message has failed, this view allows you to understand whether the failure can be attributed to a specific mediator/endpoint in the message flow.
Recommended action	Check whether the sequence in which the mediation is performed by different mediators, and the sequence in which the message is sent to different endpoints are correct. Click on each mediator in the message flow and view the MEDIATOR PROPERTIES gadget to identify the changes to the payload made by the mediator as well as the context and transport properties added to/removed from the mediation flow by the mediator. This allows you to evaluate whether the mediation is performed as expected. Click on an endpoint and view the MEDIATOR PROPERTIES gadget to identify the changes to the payload made before the endpoint and after the endpoint.

Mediator Properties

View (Example)
Description	This gadget displays the payload of the selected message before and after the selected mediator/sequence/endpoint. It also shows the context and transport properties in the mediation flow before and after the selected mediator/sequence/endpoint.
Purpose	This gadget allows you to analyze the nature of processing carried out by each EI artifact included in the message flow that a message has passed through. If a message has failed, this gadget allows you to identify the exact stages in the message flow where the errors have occurred.
Recommended action	Click on the required mediator/endpoint/sequence in the MESSAGE FLOW gadget in order to update this gadget with information about it. Consider the Before section as the input of the selected artifact, and the After section as the output. Check whether the transformation that has been made is the the same as what is required.
