Always start the recording before embarking on any service testing activities. This is to ensure that all measurement data is captured; the advice applies just as well to scripts as to manually handled testing (see section "Manual Recording").

Be aware that logfiles always record data from all activated devices (among those selected for inclusion in the recording), not only the devices that participate in the script (i.e. those that have some device-specific activity assigned to them).

The automatic data buffering in TEMS Investigation may result in overlap between logfiles, as explained in section "Buffering in Connection with Logfile Recording". If you want to avoid this, set the buffer length lower or to zero. Alternatively, you can insert Wait activities of suitable duration in your script to separate Stop Recording activities from Start Recording activities that will follow immediately in the execution flow. For example, in a loop that begins with Start Recording and ends with Stop Recording, insert a Wait at the end.

Other methods of recording are independent of scripted recording and do not affect a script that is executing. See section "Recording Logfiles".
