NAME         top

       ganglia2pcp - import ganglia data and create a PCP archive

SYNOPSIS         top

       ganglia2pcp [-d outdir] [-e end] [-f outfile] [-h hostname] [-s
       start] [-V version] [-Z timezone] input_dir

DESCRIPTION         top

       ganglia2pcp is intended to read a set of ganglia files stored in
       the rrd format and translate them into a Performance Co-Pilot
       (PCP) archive with the basename outfile.

       The intent of this converter is to take all of the rrd files
       found in the input_dir and generate a single pcp archive file.
       The mapping of ganglia metrics to pcp metrics is defined

       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 sar2pcp will not overwrite them and will exit with
       an error message of the form

       __pmLogNewFile: ``blah.0'' already exists, not over-written

       ganglia2pcp 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.  The RRDs Perl
       wrapper is used to parse the raw rrd format files.

OPTIONS         top

       The available command line options are:

       -d outdir
            The outdir argument specifies a output to write to.  The
            default is the current directory.

       -e end
            The end argument specifies a end time in a format understood
            by str2time.  The default start time is current time.

       -f outfile
            The outfile argument specifies a output file name.  The
            default name is in the standard pmlogger format based on the
            start time, e.g., 20150201.00.10.

       -h hostname
            The hostname argument specifies a hostname to write to the
            archive.  The default is taken from the directory name that
            the rrd files reside in.

       -s start
            The start argument specifies a start time in a format
            understood by str2time.  The default start time is 24 prior
            to current time.

       -V version
            The -V option specifies the version for the output PCP
            archive.  By default the archive version
            $PCP_ARCHIVE_VERSION (set to 3 in current PCP releases) is
            used, and the only values currently supported for version
            are 2 or 3.

       -Z timezone
            The timezone argument sets the source timezone in the PCP
            archive (the default is to use the local timezone).  The
            timezone must have the format +HHMM (for hours and minutes
            East of UTC) or -HHMM (for hours and minutes West of UTC) or
            UTC.  Note in particular that neither the zoneinfo (aka
            Olson) format, e.g. Europe/Paris, nor the Posix TZ format,
            e.g.  EST+5 is allowed.  Example: timezone=``+1100''.


       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
