PMJSON(1) General Commands Manual PMJSON(1)


pmjson - Performance Co-Pilot JSON dumping utility


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


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.


The available command line options are:

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.
Produce JSON output with all superflous whitespace removed from the resulting JSON string.
Formatted output is written to the named outfile. If this option is omitted, then pmjson will write to the standard output stream.
Produce JSON output in a human-readable format.
Verify the input as valid JSON only, no output is produced.
Display version number and exit.
Produce YAML-like output, a human-readable format with less syntactic sugar than JSON.
-?, --help
Display usage message and exit.


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).


PMWEBAPI(3), pcp.conf(5) and pcp.env(5).
