NAME¶
pmjson - Performance Co-Pilot JSON dumping utility
SYNOPSIS¶
pmjson [-mpqy] [-i|--in FILE]
[-o|--out FILE]
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.
The available command line options are as follows:
- -i|--in FILE
- JSON formatted input FILE - path to a file from which input should
be read. If this option is omitted, then pmjson will read from the
standard input stream.
- -o|--out FILE
- Formatted output is written to the named FILE. If this option is
omitted, then pmjson will write to the standard output stream.
- -m|--minimal
- Produce JSON output with all superflous whitespace removed from the
resulting JSON string.
- -p|--pretty
- Produce JSON output in a human-readable format.
- -q|--quiet
- Verify the input as valid JSON only, no output is produced.
- -y|--yaml
- Produce YAML-like output, a human-readable format with less syntactic
sugar than JSON.
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).
