Logging

Libretto 2 writes four (4) kinds of logs into text files, on the PC it (the inlet) is running on. It is possible to control which ones of these - if any - are written. You can find the setting in Management utility, under Libretto2 / Logging section.

Typically these logs should not be kept on for extended periods of time unless there is reason to do so, because they take up quite a bit of space on the hard disk. Logging should usually only be enabled fully if there is reason to believe something is not working as it should, or there is a specific problem that is being worked on. The logs provide extremely valuable information to P.V. Supa personnel in troubleshooting, so if you have any reason to believe there is something wrong with the device, you should turn on logging and inform P.V. Supa of it.

The log files are by default stored in C:\temp\logs directory, and named bu using the current date as part of the log file name. This makes it easy to find logs from any given date. The different logs are:

•Application log (<date>.lbr2.log): this log stores information about the main functionality of the Libretto 2 software, such as sorting and possible errors.

•Device log (<date>.dev.log): stores the communication information between the hardware (inlet) and software (PC).

•SIP log (<date>.SIP.log): stores information about communications between Libretto 2 software and the library system, SIP messages.

•UI log (<date>.UI.log): Libretto 2 user interface log.

If you are asked to provide these logs to a P.V. Supa technician, please compress the files before sending them as they can get very large over time. You should also monitor the hard drive available space when logging is enabled, to prevent it from filling up.
