NAME         top

       sheet2pcp - import spreadsheet data and create a PCP archive

SYNOPSIS         top

       sheet2pcp [-h host] [-V version] [-Z timezone] infile mapfile

DESCRIPTION         top

       sheet2pcp is intended to read a data spreadsheet (infile)
       translate this into a Performance Co-Pilot (PCP) archive with the
       basename outfile.

       The input spreadsheet can be in any of the common formats,
       provided the appropriate Perl modules have been installed (see
       the CAVEATS section below).  The spreadsheet must be
       ``normalized'' so that each row contains data for the same time
       interval, and one of the columns contains the date and time for
       the data in each row.

       The resultant PCP archive 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.

       The mapfile controls the import process and defines the data
       mapping from the spreadsheet columns onto the PCP data model.
       The file is written in XML and conforms to the syntax defined in
       the MAPPING CONFIGURATION section below.

       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 sheet2pcp will not overwrite them and will exit
       with an error message.

       The -h option is an alternate to the hostname attribute of the
       <sheet> element in mapfile described below.  If both are
       specified, the value from mapfile is used.

       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.

       The -Z option is an alternate to the timezone attribute of the
       <sheet> element in mapfile described below.  If both are
       specified, the value from mapfile is used.

       sheet2pcp 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 mapfile contains specifications in standard XML format.

       The whole specification is wrapped in a <sheet> ... </sheet>
       element.  The  sheet tag supports the following optional

       heading   Specifies the number of heading rows to skip at the
                 start of the spreadsheet before processing data.
                 Example: heading="1".

       hostname  Set the source hostname in the PCP archive (the default
                 is to use the hostname of the local host).  Example:

       timezone  Set the source timezone in the PCP archive (the default
                 is to use UTC).  The timezone must have the format
                 +HHMM (for hours and minutes East of UTC) or -HHMM (for
                 hours and minutes West of 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".

       datefmt   The format of the date imported from the spreadsheet
                 may be specified as a concatenation of values that
                 specify the order of the year (Y), month (M) and day
                 (D) fields in a date.  The supported variants are DMY
                 (the default), MDY and YMD.  Example: datefmt="YMD".

       A <sheet> element contains one or more metric specifications of
       the form <metric>metricname</metric>.  The metric tag supports
       the following optional attributes:

       pmid      The Performance Metrics Identifier (PMID), specified as
                 3 numbers separated by a periods (.) to set the domain,
                 cluster and item fields of the PMID, see PMNS(5) for
                 more details of PMIDs.  If omitted, the PMID will be
                 automatically assigned by pmiAddMetric(3).  The value
                 PM_ID_NULL may be used to explicitly nominate the
                 default behaviour.  Examples: pmid="60.0.2",

       indom     Each metric may have one or more values.  If a metric
                 always has one value, it is singular and the Instance
                 Domain should be set to PM_INDOM_NULL.  Otherwise indom
                 should be specified as 2 numbers separated by a period
                 (.)  to set the domain and ordinal fields of the
                 Instance Domain.  Examples: indom="PM_INDOM_NULL",
                 indom="60.3", indom="PMI_DOMAIN.4".

                 More than one metric can share the same Instance Domain
                 when the metrics have defined values over similar sets
                 of instances, e.g. all the metrics for each network
                 interface.  It is standard practice for the domain
                 field to be the same for the pmid and the indom; if the
                 pmid attribute is missing, then the domain field for
                 the indom should be the reserved domain PMI_DOMAIN.

                 If the indom attribute is omitted then the default
                 Instance Domain for the metric is PM_INDOM_NULL.

       units     The scale and dimension of the metric values along the
                 axes of space, time and count (events, messages,
                 packets, etc.) is specified with a 6-tuple.  These
                 values are passed to the pmiUnits(3) function to
                 generate a pmUnits structure.  Refer to pmLookupDesc(3)
                 for a full description of all the fields of this
                 structure.  The default is to assign no scale or
                 dimension to the metric, i.e. units="0,0,0,0,0,0".
                 Examples: units="0,1,0,0,PM_TIME_MSEC,0"

       type      Defines the data type for the metric.  Refer to
                 pmLookupDesc(3) for a full description of the possible
                 type values; the default is PM_TYPE_FLOAT.  Examples:
                 type="PM_TYPE_32", type="PM_TYPE_U64",

       sem       Defines the semantics of the metric.  Refer to
                 pmLookupDesc(3) for a full description of the possible
                 values; the default is PM_SEM_INSTANT.  Examples:
                 sem="PM_SEM_COUNTER", type="PM_SEM_DISCRETE".

       The remaining specifications define the data columns in order
       using exactly one <datetime></datetime> element, one or more
       <data>metricspec</data> elements and one or more <skip></skip>

       The <datetime> element defines the column in which a date and
       time will be found to form the timestamp in the PCP archive for
       all the data in each row of the PCP archive.

       For the <data> element, a metricspec consists of a metric name
       (as defined in an earlier <metric> element), optionally followed
       by an instance name that is enclosed by square brackets, e.g.
       <data>hinv.ncpu</data>, <data>kernel.all.load[1 minute]</data>.

       The skip tag defines the column that should be skipped when
       preparing data for the PCP archive.

       The order of the <datetime>, <data> and <skip> elements matches
       the order of columns in the spreadsheet.  If the number of
       elements is not the same as the number of columns a warning is
       issued, and the extra elements or columns generate no metric
       values in the output archive.

       The mapfile ...

             <sheet heading="1">
                 <!-- simple example -->

CAVEATS         top

       Only the first sheet from infile will be processed.

       Additional Perl modules must be installed for the various spread‐
       sheet formats, although these are checked for ar run-time so only
       the modules required for the specific types of spreadsheets you
       wish to process need be installed:

       *.csv Spreadsheets in the Comma Separated Values (CSV) format re‐
             quire Text::CSV_XS(3pm).

       *.sxc or *.ods
             OpenOffice documents require Spreadsheet::ReadSXC(3pm),
             which in turn requires Archive::Zip(3pm).

       *.xls Classical Microsoft Office documents require Spread‐
             sheet::ParseExcel(3pm), which in turn requires OLE::Stor‐

             Microsoft OpenXML documents require Spreadsheet::XLSX(3pm).
             sheet2pcp does not appear to work with OpenXML documents
             saved from OpenOffice.


       Environment variables with the prefix PCP_ are used to parameter‐
       ize the file and directory names used by PCP.  On each installa‐
       tion, the file /etc/pcp.conf contains the local values for these
       variables.  The $PCP_CONF variable may be used to specify an al‐
       ternative configuration file, as described in pcp.conf(5).
