#################################################################################################### # 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 ----------------------------------------------------------------------------------------------- |Memory Usage Test sample output |----------------------------------------------------------------------------------------------- |<test-report> | <test-information> | <os-name>Windows XP</os-name> | <java-version>1.5.0_05</java-version> | <jvm_memory_settings> | <heap_memory> | <committed>9502720</committed> | <max>66650112</max> | </heap_memory> | <non_heap_memory> | <committed>30736384</committed> | <max>121634816</max> | </non_heap_memory> | </jvm_memory_settings> | <test-settings> | <durable>non-durable</durable> | <message_size>10240</message_size> | <destination_name>FOO.BAR</destination_name> | <connection_checkpoint_size>-1</connection_checkpoint_size> | <consumer_count>1</consumer_count> | <report_name>activemq-memory-usage-report</report_name> | <prefetchSize>-1</prefetchSize> | <domain>topic</domain> | <producer_count>1</producer_count> | <connection_checkpoint_size_kb>-1</connection_checkpoint_size_kb> | <message_count>100000</message_count> | <report_directory>C:\Projects\logicblaze\activemq\activemq-perftest\target/test-memtest</report_directory> | </test-settings> | </test-information> | <test-result checkpoint_interval_in_sec=5 > | <memory_usage index=0 non_heap_mb=21 non_heap_bytes=22963904 heap_mb=6 heap_bytes=7275808/> | <memory_usage index=1 non_heap_mb=23 non_heap_bytes=24598560 heap_mb=11 heap_bytes=12474400/> | .... | .... | </test-result> |</test-report> | -------------------------------------------------------------------------------------------------
