There is two properties that controls how many VSE matching related events are buffered.
lisa.vse.match.event.buffer.size and lisa.vse.request.event.set.buffer.size - the default value for these properties are 100 and 50 respectively.
We recommend increasing the buffer size limit only if you are doing some debugging. Increasing these values can impact VSE performance during a performance test.
Usage:
Add these properties to the local.properties file on the VSE server and restart the components.
lisa.vse.match.event.buffer.size=200
lisa.vse.request.event.set.buffer.size=200
When you have additional steps(like JDBC Step) in the VSM, verify if the "Quiet" option is enabled in the step information inside the VSM. When you disable it for these additional steps you will be able to see all the steps execution in the Inspection View.
Hope this helps.
