# 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.
                          |

                          |
                          |    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 : 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

                          |                                    send/consume messages using one producer/consumer conneciton
                          |                                  - default value : -1
