14. Generating Report Dashboard

> JMeter supports dashboard report generation to get graphs and statistics from a test plan.
> This chapter describes how to configure and use the generator.

> 14.1 Overview

> > The dashboard generator is a modular extension of JMeter. Its default behavior is to read and process samples from CSV files to generate HTML files containing graph views. It can generate the report at end of a load test or on demand.

> > This report provides the following metrics:

> > - APDEX (Application Performance Index) table that computes for every transaction the APDEX based on configurable values for tolerated and satisfied thresholds
> > - A request summary graph showing the Success and failed requests (Transaction Controller Sample Results are not taken into account) percentage:

> > - A Statistics table providing in one table a summary of all metrics per transaction including 3 configurable percentiles :

> > - An error table providing a summary of all errors and their proportion in the total requests :

> > - A Top 5 Errors by Sampler table providing for every Sampler (excluding Transaction Controller by default) the top 5 Errors :

> > - Zoomable chart where you can check/uncheck every transaction to show/hide it for:
> >   - Response times Over Time (Includes Transaction Controller Sample Results) :

> >   - Response times Percentiles Over Time (successful responses only) :

> >   - Active Threads Over Time :

> >   - Bytes throughput Over Time (Ignores Transaction Controller Sample Results) :

> >   - Latencies Over Time (Includes Transaction Controller Sample Results) :

> >   - Connect Time Over Time (Includes Transaction Controller Sample Results) :

> >   - Hits per second (Ignores Transaction Controller Sample Results):

> >   - Response codes per second (Ignores Transaction Controller Sample Results):

> >   - Transactions per second (Includes Transaction Controller Sample Results):

> >   - Response Time vs Request per second (Ignores Transaction Controller Sample Results):

> >   - Latency vs Request per second (Ignores Transaction Controller Sample Results):

> >   - Response time Overview (Excludes Transaction Controller Sample Results) :

> >   - Response times percentiles (Includes Transaction Controller Sample Results):

> >   - Times vs Threads (Includes Transaction Controller Sample Results):

> >     In distributed mode, this graph shows a horizontal axis the number of threads for 1 server. It's a current limitation

> >   - Response Time Distribution (Includes Transaction Controller Sample Results):

> 14.2 Configuring Dashboard Generation

> > Dashboard generation uses JMeter properties to customize the report. Some properties are used for general settings and others are used for a particular graph configuration or exporter configuration.

> > All report generator properties can be found in file `reportgenerator.properties`. To customize these properties, you should copy them in `user.properties` file and modify them.

> > 14.2.1 Requirements

> > > 14.2.1.1 Filtering configuration

> > > > `jmeter.reportgenerator.exporter.html.series_filter`
> > > > `Search|Order`

> > > >     jmeter.reportgenerator.exporter.html.series_filter=^(Search|Order)(-success|-failure)?$

> > > 14.2.1.2 Save Service configuration

> > > > To enable the generator to operate, the CSV file generated by JMeter must include certain required data which are correct by default in the last live version of JMeter.
> > > > If you modified those settings, check that your JMeter configuration follows these settings (these are the defaults):

> > > >     jmeter.save.saveservice.bytes = true
> > > >     # Only available with HttpClient4
> > > >     #jmeter.save.saveservice.sent_bytes=true
> > > >     jmeter.save.saveservice.label = true
> > > >     jmeter.save.saveservice.latency = true
> > > >     jmeter.save.saveservice.response_code = true
> > > >     jmeter.save.saveservice.response_message = true
> > > >     jmeter.save.saveservice.successful = true
> > > >     jmeter.save.saveservice.thread_counts = true
> > > >     jmeter.save.saveservice.thread_name = true
> > > >     jmeter.save.saveservice.time = true
> > > >     jmeter.save.saveservice.connect_time = true
> > > >     jmeter.save.saveservice.assertion_results_failure_message = true
> > > >     # the timestamp format must include the time and should include the date.
> > > >     # For example the default, which is milliseconds since the epoch:
> > > >     jmeter.save.saveservice.timestamp_format = ms
> > > >     # Or the following would also be suitable
> > > >     # jmeter.save.saveservice.timestamp_format = yyyy/MM/dd HH:mm:ss

> > > 14.2.1.3 Transaction Controller configuration

> > > > If you use `Transaction Controller`s, to ensure most accurate results:

> > > > - uncheck the box (this is the default configuration): `Generate parent sample`

> > > > - If `Transaction Controller` is used as a Container to represent a request for an HTML Page that will trigger Ajax calls and you only want in your report the Transaction Controller, then Right click on the node and Apply Naming Policy

> > > >   You will obtain this:

> > > date_format

> > > Default date format from SimpleDateFormat Java API with Locale.ENGLISH.
> > > Default Date format is `yyyyMMddHHmmss`
> > > Useful when you would like to generate a report after the load test, and the results file contains timestamp in another time zone. In this case the date format must include the time zone (zzz).

> > > 14.2.4.4 Filtering mechanisms

> > > > Unlike the filtering in the section General properties which discards data before calculations, here the filtering is performed after the calculations and serves to simplify the final report.

> > > > The property `series_filter` allows to filter which series of a graph (resp. rows of a summary table) using regular expression that matches the name of the series (resp. of the row). However, even if the name of the series (resp. row) matches the filter, the setting of the other filtering properties can lead to its discarding. Conversely if there is no matching, the other properties can allow to keep it.

> > > > The following tables show how the setting of filtering properties works.

> > > > Incorrect filter configuration can lead to generate empty graphs/summary tables:
> > > > - If you set the property `show_controllers_only` and the graph is configured to exclude controllers.
> > > > - If the property `series_filter` matches none series.

> > 14.2.5 Sample configuration
