Measuring the DAS Performance

This section explains how to measure the performance of WSO2 DAS by configuring properties to calculate the TPS (Throughput Per Second) at a specified frequency.

To enable the WSO2 DAS to print the TPS in the CLI logs, configure the following properties when you start the DAS server.

Property Description

-DprofilePersistence To enable WSO2 DAS to print the TPS in the CLI logs, this property should be set to true. The TPS is calculated a printed for the number of events specified for the persistenceStatsCutoff property (described below).

-DpersistenceStatsCutoff

This parameter specifies the number of events for which the TPS should be printed in the CLI logs.

e.g., If -DpersistenceStatsCutoff=1000, the TPS is printed in the logs for every 1000 events processed by WSO2 DAS.

If this property is not configured when -DprofilePersistence property is set to true, the TPS is printed for every 100000 events.

Example

You can enable WSO2 DAS to print TPS for every 1000 events as follows:

On Windows: wso2server.bat --run -DprofilePersistence=true -DpersistenceStatsCutoff=1000
On Linux/Mac OS: sh wso2server.sh -DprofilePersistence=true -DpersistenceStatsCutoff=1000
