System Log Files

This logs_system_objects.cfg example specifies system log files with associated update and size data.  Various Pikt scripts reference this to handle log file rotation and truncation, also to report when log files aren't being updated.

// these fields must be tab-delimited!  from this point onward, the only
// spaces in this file should be in preprocessor directive lines (for example,
// '#if piktmaster') or comment lines, or in preproc or postproc fields

// all numeric fields must be actual numbers, not for example, 2*60*60 or
// 2*=KB, but rather 7200 or 2048

// when both days and secs are 0, this is the signal for PIKT to skip the
// fileage (and existence) test

// for the binary field, binary files are 1, text files are 0

// maxsize is in KB; a negative number for the maxsize says not to truncate,
// to report only

// preproc is the command(s), if any, to do pre-truncation (for example, to
// stop a daemon)
// postproc is the command(s), if any, to do post-truncation (for example, to
// restart a daemon)

On the piktmaster system, we would install the LogsSystem.obj file to each PIKT slave system with the command:

# piktc -iv +O LogsSystem +H all        [or: ... -H down]
