The following sections describe the prerequisites for publishing statistics from the ESB profile of WSO2 EI to the Analytics profile.

Configuring the ESB to publish data to the Analytics profile

The required configuration details described below are available by default. Follow this section to understand the Analytics related configurations used in the process, and do any modifications if required. In a clustered deployment, the following configurations should be checked for each Enterprise Integrator node in the cluster.

This step involves providing the information required by the ESB profile to publish data to WSO2 EI Analytics in order to analyze the data via the Analytics Dashboard. 


To configure EI Analytics, open the <EI_HOME>/conf/carbon.xml file. Under <Analytics>, enter the relevant configurations as described in the table below. 

PropertyRequired ValueExample
ServerURL

The URL to which the EI statistics are published as events. The format of this URL can be one of the following:

  • <protocol>://<hostname
  • <ip>:<port>

When you deploy EI Analytics as an HA cluster, enter the URLS of the Analytics nodes as a list of comma-separated URLS.

AuthServerURL

When the authentication of EI statistics published to EI Analytics is carried out in a separate server, set this parameter to specify the URL of that authentication server.

The format of this URL can be one of the following:

  • <protocol>://<hostname
  • <ip>:<port>
ssl://localhost:7712
UsernameThe username to use when accessing the WSO2 EI Analytics server to publish configurations.admin
PasswordThe password to use when accessing the WSO2 EI Analytics server to publish configurations.admin


Enabling statistics/message tracing

Follow the instructions give below to enable statistics monitoring and message tracing. You can use message tracing to track a message (including the message payload) throughout a mediation flow.

Note that it is not recommended to enable tracing in production environments as it generates a large number of events that reduces the performance of the analytics profile. Therefore, tracing should only be enabled in development environments.

Step 1: Enabling statistics/message tracing for the ESB profile

Open the synapse.properties file (stored in the <EI_HOME>/conf/ directory) and configure the properties given below.

PropertyDescription
mediation.flow.statistics.enable

Set this property to true and enable statistics for the required ESB artifact, to record information such as the following.

  • The time spent on each mediator.
  • The time spent to process each message.
  • The fault count of a single message flow.
mediation.flow.statistics.tracer.collect.payloads

Set this property to true and enable tracing for the required ESB artifact, to record the message payload before and after the mediation performed by individual mediators. Note that message tracing is not recommended for production environments.

mediation.flow.statistics.tracer.collect.properties

Set this property to true and enable tracing for the required ESB artifact, to record the following information.

  • Message context properties.
  • Message transport-scope properties. 

Note that message tracing is not recommended for production environments.

mediation.flow.statistics.collect.all

Set this property to true and set the mediation.flow.statistics.enable property also to true, to enable mediation statistics for all the artifacts in the ESB profile by default.

If you set this property to false, you need to set the mediation.flow.statistics.enable property to true and manually enable statistics for the required ESB artifact.

Step 2: Enabling statistics/message tracing for ESB artifacts

If you have enabled the mediation.flow.statistics.collect.all property in the synapse.properties file as explained in the previous section, you will be monitoring the statistics of all the ESB artifacts (proxy services, REST APIs, sequences, and endpoints)  by default. Alternatively, you have the option of enabling statistics for only the required artifacts. You can use WSO2 Integration Studio or the management console for this purpose.

In a clustered deployment, statistics should be enabled for the required artifacts in all the EI nodes if you have not enabled deployment synchronizing. If deployment synchronising is enabled, you need to enable statistics for the required artifacts only in one node.

For example, you can enable statistics for a proxy service as described below.

  1. Start the ESB profile and log into the management console.
  2. In the Main tab, look for the Services section and click List  under the same section to open the Deployed Services page. Then click on the required proxy service as shown below.
     
  3. Click Enable Statistics and Enable Tracing links. Note that message tracing is not recommended for production environments. 
    Click OK in the information message that appears to confirm that statistics/tracing is enabled.
     
The following table specifies the path to the Enable Statistics link for each ESB artifact type that can be analyzed using the Analytics Dashboard.


EI Artifact TypePath
Proxy ServiceMain tab => Services => List => Deployed Services page => <Proxy_Service_Name>
REST APIMain tab => APIs => Deployed APIs page
SequenceMain tab => Sequences => Mediation Sequences page
EndpointMain tab => Endpoints => Manage Endpoints page
Inbound EndpointMain tab => Inbound Endpoints => Manage Inbound Endpoints page

If you have worker nodes configured in your deployment, use WSO2 Integration Studio to enable message tracing/statistics as follows. You need to set the value of the Trace Enabled and Statistics Enabled options to true in the Properties tab of the artifact. Note that message tracing is not recommended for production environments.
