# Running Maven 2 Memory usage Test
####################################################################################################
Goal | Description
--------------------------|----------------------------------------------------------
activemq-memtest:memtest | Starts the broker, producer, consumer and the memory monitoring thread all in the same VM and
| generate the heap and non-heap memory usage of the jvm.
| The plugin is included by default in the \activemq-perf module.
|
| Parameters :
|
| 1. -DmessageCount - specifies number of messages to send/receive
| - default value : 100000
|
| 2. -Dtopic - specifies domain type. Valid value is true or false
| - default value : true
|
| 3. -Ddurable - specifies delivery mode: Valid value is true or false
| - default value : false
|
| 4. -DconnectionCheckpointSize - specifies size of messages sent in KB before we close and
| start the producer/consumer to see if there is a memory
| leak using different connections.
| - a value of -1 indicates that no checkpoint is set and will
| send/consume messages using one producer/consumer conneciton
| - default value : -1
|
| 5. -DmessageSize - specifies the message size in bytes
| - default value : 10240 (10KB)
|
| 6. -DcheckpointInterval - specifies the interval in seconds on which the monitoring tool
| will get the memory usage of test run.
| - default value : 2 (seconds)
|
| 7. -DprefetchSize - specifies the prefetch size to be used
| - a value of -1 will indicates that test will use the default prefetch
| size (32000)
| - default value : -1
|
| 8. -Durl - species the broker url to use if not going to be using the embedded broker
| - default value : null
|
| 9. -DreportName - specifies the name of the output xml file.
| - default value : activemq-memory-usage-report
|
| 10. -DreportDirectory - specifies the directory of the output file
| - default value : ${project.build.directory}/test-memtest
|
| 11. -DproducerCount - specifies the number of producers
| - default value : 1
|
| 12. -DconsumerCount - specifies the number of consumers
| - default value : 1
