Detailed Description

Collects number of pass and fail invokes.

Author

Dmitry Latnikov

Details:

Collects number of pass and fail invokes.
Success rate and number of fails are calculated from this data.
Calculation is provided by aggregators:

• SuccessRateAggregatorProvider
  
• SuccessRateFailsAggregatorProvider
  

Usage example in XML:

To use this collector add metric-success-rate collector to info-collectors block.

            <!-- begin: following section is used for docu generation - metric-success-rate -->

            <!--    Example #1: Success rate metric with default aggregators
                    plotData = true => metric vs time data will be saved (displayed in WebUI and PDF report)
                    saveSummary = true => summary value for summary page will be not saved -->
            <metric xsi:type="metric-success-rate" plotData="true" saveSummary="false"/>



            <!--    Example #2: Success rate metric with custom name and default aggregators -->
            <metric id="CustomNameSuccessRate" xsi:type="metric-success-rate" plotData="true" saveSummary="false"/>



            <!--    Example #3: Success rate metric with custom name and custom aggregators
                    With this setup success rate will be aggregated on interval like on picture below -->
            <metric id="CustomSuccessRatePlot" xsi:type="metric-success-rate" plotData="true" saveSummary="false">
                <metric-aggregator xsi:type="metric-aggregator-avg"/>
            </metric>

            <!-- end: following section is used for docu generation - metric-success-rate -->

Result example:

Success rate data with default accumulative aggregators

Success rate data with aggregator: average on interval
