openUTM only maintains the SYSLOG as a file generation group if a file generation group called SYSLOG exists in the filebase base directory at the start of the application.
You must create this file generation group using the KDCSLOG tool (see also section "The KDCSLOG tool for creating the SYSLOG-FGG").
A File Generation Group (FGG) is a directory with files that are numbered consecutively using their file names (e.g. 0001, 0002,...). The files are called file generations of the FGG. The numbers are referred to as the file generation numbers.
When the FGG is created with KDCSLOG, the INFO file is also created and written in the FGG. The first time the application starts, openUTM creates the first file generation 0001 in the FGG and opens it as the SYSLOG file. All processes of the application write the messages with the destination SYSLOG in this file generation first.
When switching files, openUTM automatically creates the next generation.
If the file generation with the generation number n is the last file in which openUTM has written before the end of an application run, openUTM creates the file generation (n+1) with the next application start and opens this generation as the SYSLOG file.
The FGG contains a maximum of m file generations. The number m is defined when creating the FGG with the KDCSLOG tool. As soon as openUTM creates the (m+1)-th file generation, the oldest file generation is deleted, i.e. the file generation with the lowest generation number.
