PMIE2COL(1) General Commands Manual PMIE2COL(1)
pmie2col - convert pmie output to multi-column format
pmie2col [-?] [-d delimiter] [-p precision] [-w width]
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.
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.
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

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).
