MRTG2PCP(1) General Commands Manual MRTG2PCP(1)
mrtg2pcp - import MRTG data and create a PCP archive
mrtg2pcp hostname devname timezone infile outfile
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 pcp.conf(5).

PCP::LogImport(3).
