NAME¶

pmjson - Performance Co-Pilot JSON dumping utility

SYNOPSIS¶

pmjson [-mpqyV?] [-i infile] [-o outfile]

DESCRIPTION¶

pmjson is used to manipulate JSON (JavaScript Object Notation) formatted text used in the Performance Co-Pilot (PCP toolkit). It can produce minimal and human readable output formats when it is supplied with valid JSON input.

OPTIONS¶

The available command line options are:

-i infile, --in=infile

JSON formatted input infile - path to a file from which input should be read. If this option is omitted, then pmjson will read from the standard input stream.

-m, --minimal

Produce JSON output with all superflous whitespace removed from the resulting JSON string.

-o outfile, --out=outfile

Formatted output is written to the named outfile. If this option is omitted, then pmjson will write to the standard output stream.

-p, --pretty

Produce JSON output in a human-readable format.

-q, --quiet

Verify the input as valid JSON only, no output is produced.

-V, --version

Display version number and exit.

-y, --yaml

Produce YAML-like output, a human-readable format with less syntactic sugar than JSON.

-?, --help

Display usage message and exit.

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).
