Merging Load Test Results

To run a big load test, it can be necessary to start the load test from multiple controllers. Consequently, Silk Performer will generate multiple result folders - one folder per controller. Use the Merge Results feature to merge the results into one result folder. This allows you to view all metrics in a single comprehensive report.

Note: Results from different projects cannot be merged.
  1. On the Results tab, in the Data Processing group, click Merge Results.
  2. Drag two or more load test result folders from a file explorer onto the table or click Add to browse for result folders.
  3. Specify a master load test in the Master column. Some values from the result files cannot be merged (like the project description). In such a case, Performance Explorer will use the value of the master load test.
  4. Select a Merge type:
    • absolute: In a report, the results will display with their actual start time on the time line. For example: If you started a load test on Controller B 10 seconds after you started the load test on Controller A, the results will display on the time line accordingly.
    • relative: In a report, all results will display with the same start time on the time line, regardless of the actual start times of the load tests.
  5. Specify an Interval for the merged .tsd files. The minimum interval (shown in the Interval list) is the lowest common multiple of the intervals from all .tsd files that are located in the specified results folders.
  6. Specify a Target folder. The merged results will be stored in this folder.
  7. Click Merge.
When the results are merged successfully, Performance Explorer displays an overview report. This newly created report has the workload type Merged Workload, which contains all executed usergroups.
