PMIE2COL(1)              General Commands Manual             PMIE2COL(1)

НАЗВАНИЕ

       pmie2col - convert pmie output to multi-column format

СИНТАКСИС

       pmie2col [-?]  [-d delimiter] [-p precision] [-w width]

ОПИСАНИЕ

       pmie2col is a simple tool that converts output from pmie(1) into
       regular column format.  Each column is 7 characters wide (by
       default, may be changed with the -w option) with a single space
       between columns.  That single space can be substituted with an
       alternate delimiter using the -d option (this is useful for
       importing the data into a spreadsheet, for example).

       The precision of the tabulated values from pmie can be specified
       with the -p option (default is 2 decimal places).  This option
       can and will override any width setting in order to present the
       requested precision.

       The pmie(1) configuration must follow these rules:

       (1)    Each pmie(1) expression is of the form ``NAME = expr;''.
              NAME will be used as the column heading, and must contain
              no white space, although special characters can be escaped
              by enclosing NAME in single quotes.

       (2)    The ``expr'' must be a valid pmie(1) expression that
              produces a singular value.

       In addition, pmie(1) must be run with the -v command line option.

       It is also possible to use the -e command line to pmie(1) and
       output lines will be prefixed by a timestamp.

ПАРАМЕТРЫ

       The available command line options are:

       -d char, --delimiter=char
            Use char as output delimiter.

       -p N, --precision=N
            Use n as output floating point precision.

       -w N, --width=N
            Use n as output column width.

       -?, --help
            Display usage message and exit.

ПРИМЕРЫ

       Given this pmie(1) configuration file (config):

            loadav = kernel.all.load #'1 minute';
            '%usr' = kernel.all.cpu.user;
            '%sys' = kernel.all.cpu.sys;
            '%wio' = kernel.all.cpu.wait.total;
            '%idle' = kernel.all.cpu.idle;
            'max-iops' = max_inst(disk.dev.total);

       Then this command pipeline:

            $ pmie -v -t 5 <config | pmie2col -w 8

       Produces output like this:

               loadav     %usr     %sys     %wio    %idle max-iops

СРЕДА PCP

       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).
