GBT is a Perl script that can condense and extract meaningful information from time-indexed logs and numbers. GBT is Group-By-Time and rather than have sporadic bursts of data separated by black holes of emptiness, GBT produces a consistent flow of data that is easily graphable
GBT by default will condense data into ten minute blocks of maximum values for each column given. The size of the time block can be changed using the -t argument. The output data format can be changed to provide min, max, mean, sum, delta or count.
The main use for GBT is to pipe data into GNU Plot to produce graphs.
Here is the gnuplot PNG created from the sample data.
