NAME

       ganglia2pcp - import ganglia data and create a PCP archive

SYNOPSIS

       ganglia2pcp [-d outdir] [-e end] [-f outfile] [-h hostname] [-s start] [-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.

       -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).
