pmie2col

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.

Options

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.

Examples

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).
