NAME         top

       mrtg2pcp - import MRTG data and create a PCP archive

SYNOPSIS         top

       mrtg2pcp hostname devname timezone infile outfile

DESCRIPTION         top

       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 archive may be used with all 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.


       Environment variables with the prefix PCP_ are used to
       parameterize the file and directory names used by PCP.  On each
       installation, the file /etc/pcp.conf contains the local values
       for these variables.  The $PCP_CONF variable may be used to
       specify an alternative configuration file, as described in
