There is small command-line utility for generating graphs out of JTL files. It behave just like right-click context menu on all graphs. The tool can generate PNG, CSV or both. Note you can use GraphsGeneratorListener if you want to bulk generate graphs after a test or for existing results.

Installation

The tool is placed inside distribution ZIP. The tool consists of CMDRunner.jar and shell wrappers. Wrappers just shorten call of"java -jar CMDRunner.jar --tool Reporter ...". The tool files must be placed inside lib/ext directory of JMeter installation. The tool requires JMeterPlugins.jar to be placed in lib/ext also. The tool requires JMeter 2.4 to function properly (2.3 will work only for PNG generation).

Usage and Parameters

Generating PNG:

java -jar CMDRunner.jar --tool Reporter --generate-png test.png --input-jtl results.jtl \

  --plugin-type ResponseTimesOverTime --width 800 --height 600

Generating CSV:

java -jar CMDRunner.jar --tool Reporter --generate-csv test.csv \

  --input-jtl results.jtl --plugin-type ResponseTimesOverTime

Yoy may generate CSV and PNG in single tool run. --help will show you short help list on available parameters.

--generate-png <file>	generate PNG file containing graph
--generate-csv <file>	generate CSV file containing graph data
--input-jtl <file>	load data from specified JTL file
--plugin-type <class>	which type of graph use for results generation

Use --input-jtl merge-results.properties with --plugin-type MergeResults. The merge-results.properties file is in JMETER_HOME/bin dir.

You may customize graph drawing and data processing like GUI settings do with optional parameters:

--width <pixels>	for PNG only - width of the image, default is 800
--height <pixels>	for PNG only - height of the image, default is 600
--granulation <ms>	granulation time for samples
--relative-times <yes/no>	use relative X axis times, no will set absolute times
--aggregate-rows <yes/no>	aggregate all rows into one
--paint-gradient <yes/no>	paint gradient background
--paint-zeroing <yes/no>	paint zeroing lines
--paint-markers <yes/no>	paint markers on data points (since 1.1.3)
--prevent-outliers <yes/no>	prevent outliers on distribution graph
--limit-rows <num of points>	limit number of points in row
--force-y <limit>	force Y axis limit
--hide-low-counts <limit>	hide points with sample count below limit
--success-filter <true/false>	filter samples by success flag (since 0.5.6), possible values are true, false, if not set no filtering on success flag will occur
--include-labels <labels list>	include in report only samples with specified labels, comma-separated
--exclude-labels <labels list>	exclude from report samples with specified labels, comma-separated
--auto-scale <yes/no>	enable/disable auto-scale multipliers for perfmon/composite graph
--line-weight <num of pixels>	line thickness for graph rows
--extractor-regexps <regExps list>	list of keyRegExp and valRegExp pairs separated with {;}, only used by PageDataExtractorOverTime
--include-label-regex <true/false>	include samples using regular expression
--exclude-label-regex <true/false>	exclude samples using regular expression
--start-offset <sec>	include in report only samples with (timestamp - relativeStartTime) > startOffset
--end-offset <sec>	include in report only samples with (timestamp - relativeStartTime) < endOffset

Plugin Type Classes

Make note that you need to install corresponding plugins set to have Extras plugins available in CMD.

Most of class names are self-explanatory:

• AggregateReport = JMeter's native Aggregate Report, can be saved only as CSV
• SynthesisReport = mix between JMeter's native Summary Report and Aggregate Report, can be saved only as CSV
• ThreadsStateOverTime = Active Threads Over Time
• BytesThroughputOverTime
• HitsPerSecond
• LatenciesOverTime
• PerfMon = PerfMon Metrics Collector
• DbMon = DbMon Metrics Collector, DataBase, get performance counters via sql
• JMXMon = JMXMon Metrics Collector, Java Management Extensions counters
• ResponseCodesPerSecond
• ResponseTimesDistribution
• ResponseTimesOverTime
• ResponseTimesPercentiles
• ThroughputVsThreads
• TimesVsThreads = Response Times VS Threads
• TransactionsPerSecond
• PageDataExtractorOverTime
• MergeResults = MergeResults Command Line Merge Tool to simplify the comparison of two or more load tests, need properties file (like merge-results.properties)

Other Ways to Automate Reporting

You can use BM.Sense service to automate test results storage and reporting. See also: BM.Sense Uploader plugin.
