NAME

       ganglia2pcp - import ganglia data and create a PCP archive

SYNOPSIS

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

DESCRIPTION

       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 internally.

       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

       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 2 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''.

PCP ENVIRONMENT

       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).
