When you run a scenario, by default all the run data is stored locally on each load generator. After scenario execution, the results must be collated—that is, the results from all of the load generators must be gathered and transferred to the results folder–before any analysis data can be generated.
In addition, data from the diagnostics servers must be collated as well.
You can set LoadRunner to collate the run data automatically, as soon as the run is complete. Alternatively, you can collate the run data manually after the run. This way, you can save and close a scenario and collate the data after reopening the scenario in Controller.
The data that is collated include the result, diagnostics, and log files. After LoadRunner has successfully collated the data, these files are deleted from the load generators from which they were gathered.
Note: In Expert mode, you can disable the collation of the log file collation (see How to Configure Scenario Options).
