Changelog

0.5.2 May 14, 2012

Inter-Thread Communication: plugins & functions
added JMX metrics for PerfMon (see forums topic)
An option to ignore some samples by sample Label - at Rows tab
file header and footer in Flexible File Writer
added a LockFile plugin to prevent simultaneous tests to run on same machine
ability to disable Composite Graph auto zoom
new perfmon wizard
some bugs fixed ( issue 102 and others)
allow label parameter for PerfMon metrics
sent JMeter maintainers a patch for undo/redo feature (for their issue 42248)
added kg.apc.jmeter.samplers.FileReadChunkSize property to control direct file sending performance
Calculate aggregate values only for selected rows - via include/exclude sample labels at Rows tab
Raw Data Source can read binary data
ability to set line thickness (0 = no line) and markers display in chart settings tab
added a property to change CSV export time format (jmeterPlugin.csvTimeFormat)

76 metrics
ability to configure PerfMon to monitor single process name/pid/filesystem/network interface.
can use UDP or TCP transport
ability to monitor custom values
old agent still supported transparently

Fix Issue 75 , Issue 76 , Issue 79 , Issue 81 , Issue 82 , Issue 85 , Issue 87 , Issue 90 , Issue 91 , and some others
Start option (-JforcePerfmonFile=true) to automatically save PerfMon metrics in a file named perfmon_yyyyMMdd-HHmmss.csv if no file is specified and test is run in non GUI mode
Checkbox "overwrite existing file" in Flexible File Writer
Saving sample_variables in Flexible File Writer
Option to change graph type for Response Time Distribution (bar, line or new cubic spline chart)
New Variable from CSV Config - Rich gui with preview, correct scope of variables (will work with perfmon, previous was not)
The plugins now use a caching mechanism to manipulate charts. This can provide big performance improvements in some cases.

fixed issue 39 , issue 48 , issue 49 , issue 51 , issue 55 , issue 64 , issue 67 , issue 72 , issue 74
no more need to set up saving active threads - it is done automatically
added Loadosophia.org Uploader

eliminated bright yellow color from graph palette
added custom functions: doubleSum, strLen, uppercase, lowercase, MD5, substring, isDefined
introduced data read limit for samplers: kg.apc.jmeter.samplers.ResultDataLimit property
add latency and sampler data fields to DummySampler
PerfMon reingeneering - regular listener architecture
PerfMon agent option to limit monitoring of a single PID for mem and cpu

default description with link to help page for every plugin
sample test plans at wiki pages
copy row ability in UltimateThreadGroup and PerfMon GUI
proper handling of transaction controllers and samplers which download embedded resources in hit/sec, response codes and latency graphs
changed row colors generation to new algorithm, more regular
percentiles graph use fractions like 99.9
important fix: issue 38
