Log File/Audit File Rollover 
When logging to a file, SSH2 uses a round-robin mechanism to switch to a new file. Log file rollover applies both to 
auditing (to the file configured with the AUDITFILE parameter) and logging (to the file configured with the LOGFILE 
parameter). 
A log file rollover occurs when the logfile is greater than the size configured in the parameter LOGMAXFILELENGTH 
or when the audit file is greater than the size configured in the parameter AUDITMAXFILELENGTH. It is also possible 
to force the rollover via SSHCOM command (see ROLLOVER AUDITFILE and ROLLOVER LOGFILE in chapter 
"SSHCOM Command Reference". 
SSH2 implements a log file round-robin with at least 10 files. The number of files can be configured using the 
LOGFILERETENTION (or AUDITFILERETENTION) parameter. If the number of retention files is set to 0 
(LOGFILERETENTION or AUDITFILERETENTION), then the content of file configured via LOGFILE (or 
AUDITFILE) will be purged as soon as the file size reaches the maximum configured size. But it is recommended to use 
at least 10 retention files. 
Archive files generated during rollover will be created by appending a number to the log file name. The number of digits 
of the number appended will be calculated depending on the number of files to keep. 
With LOGFILERETENTION set to 10 (the default value), the archive files for a LOGFILE of SLOG will be called 
SLOG0, SLOG1, ... SLOG9. 
With LOGFILERETENTION set to 1000, the archive files for a LOGFILE of SLOG will be called SLOG000, 
SLOG001, ... SLOG999.
