What are different types of Logs in Loadrunner? What to use when?

There are three main options to capture logs in Loadrunner. Standard logs and Extended logs and Errors only. Standard logs will capture logs of each and every functionality and how the server responses for every request etc. Extended logs will capture everything including error messages and warning messages from the server including what it logs in standard. ‘Errors only’ will capture only when an error occurred while running the script. Once we the functionality of the script is correct, then we use normally errors only option to reduce the log size. Because if you select ‘extended logs’ for larger scripts, they will capture 1000s of lines of logs which will take more disk space. When we call a script in a scenario, the logging will be automatically disabled.
