PROGRAM:

NAME

pmie2col - convert pmie output to multi-column format

SYNOPSIS

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

DESCRIPTION

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.

EXAMPLE

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

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).
