I've noticed that for simple things, I can shell script something and it works fine. When things start getting complicated or there's a performance issue, I'll break out perl (or python if you like).
I'd take what you have and see if it could be done better in perl. I'm sure it'd be a lot faster and probably easier to write.

mrtg2pcp
MRTG2PCP(1) Performance Co-Pilot MRTG2PCP(1)
NAME
mrtg2pcp - Import mrtg data and create a PCP archive
SYNOPSIS
mrtg2pcp hostname devname timezone infile outfile
DESCRIPTION
mrtg2pcp is intended to read an MRTG log file as created by mrtg(1) and translate this into a Performance Co-Pilot (PCP) archive with the
basename outfile. The hostname, devname, and timezone arguments specify information about the system for which the statistics were
gathered.
The resultant PCP achive may be used with all the PCP client tools to graph subsets of the data using pmchart(1), perform data reduction
and reporting, filter with the PCP inference engine pmie(1), etc.
A series of physical files will be created with the prefix outfile. These are outfile.0 (the performance data), outfile.meta (the metadata
that describes the performance data) and outfile.index (a temporal index to improve efficiency of replay operations for the archive). If
any of these files exists already, then mrtg2pcp will not overwrite them and will exit with an error message of the form
__pmLogNewFile: "blah.0" already exists, not over-written
mrtg2pcp is a Perl script that uses the PCP::LogImport Perl wrapper around the PCP libpcp_import library, and as such could be used as an
example to develop new tools to import other types of performance data and create PCP archives.
