Submission of Log files

Log Format

In order to determine which and how many resources were used by a specific transaction, the start and stop times of all transactions are required. The time periods between start and stop times are called “end-to-end” durations of transactions. All “end-to-end” elements are included in the “.ete” file, which can be created manually or generated automatically with a script. In order to expedite the parsing process it is important to ensure that the collected measurement information is delivered in a standard pre-determined format. The format fields are defined described the underlying table.

Verification and Submission of .ete-file

Verify that the transaction start and stop times are consistent with the entries in Field1. Start and stop times can be established by converting the Unix timestamp to a Date and Time on the following web site: http://www.onlineconversion.com/unix_time.htm The parsing of the measurement data will only be accepted, if the “.ete” file is forwarded to the following web site: https://ete.contentional.eu Please follow the link to find out more about Testing Performance's Performance Modelling Services
