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

       The resultant PCP achive 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 pcp.conf(5).
