NAME

       sb2-logz - sb2 log postprocessing tool

SYNOPSIS

       sb2-logz [options] < logfile

DESCRIPTION

       sb2-logz  reads	logs  created  by scratchbox2 and writes summaries (the log files can be really huge, and manually digging out information
       from them might be a time-consuming task).

       Logs are produced when sb2 is executed with -d (debug) or -L options (e.g. "-L info")

OPTIONS

       -b     no blacklist: do not ignore log lines from functions like __xstat() (there is a built-in blacklist, which tries to minimize  "noise"
	      caused by various libraries and scratchbox2 itself)

       -B fn1,fn2,..
	      blacklist funcions fn1,fn2,..: ignore lines generated by the listed library calls.

       -d level
	      debug mode, for debugging the script itself.

       -h     show help text.

       -i     print details about 'disabled' pathnames (unmodifed paths, because mapping was momentarily disabled)

       -l     print long details (affects output of -i,-m,-r,-p etc)

       -m     print details about mapped pathnames (src->dest)

       -N     print all 'notice' messages

       -p     print details about passed pathnames ('passed path' = not mapped)

       -r     print reversed mappings (dest->src)

       -s     print process statistics

       -v     verbose mode, prints dots while reading input etc.

       -P file.dot
	      write process diagram to file.dot (postprocess it with 'dot', e.g. 'dot -Tpdf file.dot >file.pdf'

       -E file.dot
	      write execution diagram to file.dot (postprocess it with 'dot', e.g. 'dot -Tpdf file.dot >file.pdf'

       -A acct-file
	      Read process accounting information from acct-file (enhances output of -P and -E)'

BUGS

       Option -A requires an accounting log, which has to be activated separately.  Generation of accounting information typically requires super-
       user privileges (or CAP_SYS_PACCT capability on Linux).	This is an system-level  restriction,  and  not  fault	of  scratchbox2.  However,
       sb2-logz  has  some  limitations:  Correlating  information from the accounting log is based on process ids, and the heuristics may fail if
       there were really many processes; The -P, -E and -A options may be less useful for longer  runs.  Best  results	are  achieved  if  process
       accounting  is  switched on just before the scratchbox2 session is created, and switched off afterwards - and there is nothing else running
       on the host at the same time.
