Try to open a aggregate report saved into a file with the Aggregate listener. With 2.12 : sampler_label,aggregate_report_count,average,aggregate_report_median,aggregate_report_90%_line,aggregate_report_min,aggregate_report_max,aggregate_report_error%,aggregate_report_rate,aggregate_report_bandwidth SAMPLER1,204,82434,76089,129444,1159,208015,0.09313725490196079,0.03735365469805521,21.15778783560153 With nightly (and 2.13, 3.0) : Label,# Samples,Average,Median,90% Line,95% Line,99% Line,Min,Max,Error %,Throughput,Received KB/sec,Sent KB/sec SAMPLER1,204,82434,76089,129444,145355,177257,1159,208015,9.31%,.0,21.16,0.00 The %Error value : 0.09313725490196079 --> 9.31% (lost precision) The Rate value: 0.03735365469805521 --> .0 (lost value!) The bandwidth value: 21.15778783560153 -->21.16 (lost precision) The new Sent KB value will probably lost precision too. The bugzilla https://bz.apache.org/bugzilla/show_bug.cgi?id=57514 are the source of theses issues, with the FORMATS array inside the SummaryReport.java.

Hi Milamber, The export makes some rounding. It doesn't hurt me except for the Rate value. We could increase the number of decimals by 1 or 2. What do you think ? Thanks
In my opinion, the full value seems better. In my example, JMeter display 2.2 samples/min for the Rate of SAMPLER1 (calculate from 0.03735365469805521 * 60 to convert seconds to minutes) If I use 0.037 * 60 that works : 2.2 samples/min, but I use only 0.03 * 60 : 1.8 samples/min. Another example, if the rate is 0,0001234000 samples/sec, JMeter will display : 0.44 samples/hour (*60*60). If I use only 0,0001 (rounding), the calculate rate will 0.36 samples/hour... I not sure what is the good fix. a) back to the full value b) increase the number of numbers after the comma c) replace rate value in samples/sec to the calculate value of rate (sometimes per sec, per min or per hour)
If anyone objects, I will change the rounding to full value : new Format[]{ null, // Label null, // count null, // Mean null, // Min null, // Max new DecimalFormat("#0.00"), // Std Dev. //$NON-NLS-1$ new DecimalFormat("#0.000%"), // Error %age //$NON-NLS-1$ <= Here +1 decimal new DecimalFormat("#.000000"), // Throughput //$NON-NLS-1$ <= Here +3 decimal new DecimalFormat("#0.00"), // kB/sec //$NON-NLS-1$ new DecimalFormat("#0.00"), // sent kB/sec //$NON-NLS-1$ new DecimalFormat("#.0"), // avg. pageSize //$NON-NLS-1$ };
