Re^2: Debugging script with long exec time

print really has no problem here.

What would be nice is to have some small scripts to analyze the log files produced. This is one of the area that perl does really good: relatively faster handing large files and has strong regexp support. With Perl it should take one no time to develop such scripts.

This is the sort of thing I do quite often, and the programs that produce the log files are usually not even in Perl.

What important is for the log messages to convey useful information. What to log or not to log is the key.

Many profiling tools are log-analyzers! Take a look at the output from Devel::DProf or Devel::Profiler. The file produced is essentially a specially-formated log-file of subroutine entry and exit times. The dprofpp program is a log-analyzer which reads the log and produces summary reports. -sam	[reply]
