Compatible WSO2 product versions

For any WSO2 product to be compatible with BAM, it must have a data agent installed in it. Data agents allow the product to communicate with the BAM server and send statistics for analysis. The following products have the latest, compatible data agents in them by default, and therefore, are compatible with BAM 2.4.0 (or any other BAM version):

• APIM 1.5.0 
• AS 5.2.0 
• ESB 4.8.0  
• ELB 2.1.0

If a particular product version you are using does not have a data agent installed, follow the steps below to install one:

1. Check the WSO2 Release Matrix and identify the WSO2 Carbon version that your product is based on.
2. Go to WSO2 P2 repositories and select the repository that is based on the Carbon version you selected in the previous step.
   
3. Add the feature repository to your product.
   
4. Then, select the data agent that you need from the features in the repository, and install it in your product. For example, in order to send mediation statistics from WSO2 ESB to BAM, you must install Mediation Statistics Data Agent feature.
