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.
