Service Statistics Toolbox

The "Service Statistics Toolbox" is a default, out-of-the-box toolbox provided by WSO2 BAM for point-and-click installation. It includes the necessary artifacts (hive scripts, data stream definitions, properties files, gadgets etc.) required to collect and monitor statistics related to services deployed in any WSO2 service-hosting product like the WSO2 Application Server, WSO2 Data Services Server etc.

Explained below is a complete, example use case of how to extract and summarize service statistics of the WSO2 Application Server using this toolbox. The following sections are covered:

Prerequisites of the usecase

1. Download and start the WSO2 BAM server and log in to its management console. Instructions are given in section Getting Started .

2. Set up the "BAM Service Statistics Data Agent" in a selected service-hosting WSO2 product of which, you plan to gather and summaries service statistics. In this example usecase, we have used the WSO2 Application Server. For instructions on setting it up to transfer service data to WSO2 BAM, refer to section Application Server Service Stats Data Agent. Else, you can pump some sample service statistics simply by running ant command in $bam_home /samples/service-stats.

Note that you can give custom values for parameters for Data receiver URL, user name and password. Default values of them are as follows. 

 Now lets see how new values can be given as parameters   

Command with new values : ant  -Durl=tcp://localhost:7612 -Dusername=user -Dpassword=pass123

Installing the Toolbox

1. Log in to BAM's management console and select "BAM Toolbox -> Add" in the "Main" menu.

2. The "Add Tool Box" page appears. Select the "Service Stats Monitoring Toolbox" and click "Install" button. With this simple step, all required artifacts will be deployed to BAM.

3. The "Available BAM Tool Boxes" page opens with the installation status as "Installing".  Wait a few seconds and refresh the page to see the status changed to "Installed".

Executing the analytics scripts

1. After installing the toolbox, navigate to "Analytics -> List" in the "Main" menu.

2. When installing the Toolbox, an analytics script is added for execution. It can simply be executed to display statistics on the dashboard. Click the "Execute" link associated with it.

Configuring summarized database

Summarized database can be configured from master-datasources.xml in WSO2BAM/repository/conf/datasources/ directory. You need to change the following section

<datasource> 
           <name>WSO2BAM_DATASOURCE</name> 
           <description>The datasource used for analyzer data</description> 
           <definition type="RDBMS"> 
               <configuration> 
                   <url>jdbc:h2:repository/database/samples/BAM_STATS_DB;AUTO_SERVER=TRUE</url> 
                   <username>wso2carbon</username> 
                   <password>wso2carbon</password> 
                   <driverClassName>org.h2.Driver</driverClassName> 
                   <maxActive>50</maxActive> 
                   <maxWait>60000</maxWait> 
                   <testOnBorrow>true</testOnBorrow> 
                   <validationQuery>SELECT 1</validationQuery> 
                   <validationInterval>30000</validationInterval> 
               </configuration> 
           </definition> 
       </datasource>

Cassandra datasource in hive script also can be configured from master-datasources.xml.

Displaying statistics on dashboard

1. After running the hive script, navigate to "Dashboard" in the "Main" menu.

2. You should be able to see visualized data of a particular service deployed in the WSO2 Application Server. For example,
