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.
