NEWHELP(1) General Commands Manual NEWHELP(1)NAME
newhelp - generate a performance metrics help database
SYNOPSIS
$PCP_BINADM_DIR/newhelp [-V] [-n pmnsfile] [-o outputfile] [-v version] [file ...]
DESCRIPTION
newhelp generates the Performance Co-Pilot help text files used by Performance Metric Domain Agents (PMDAs).
Normally newhelp operates on the default Performance Metrics Namespace (PMNS), however if the -n option is specified an alternative names-
pace is loaded from the file pmnsfile.
When there is only one input file, the base name of the new database is derived from the name of the input file, otherwise the -o flag must
be given to explicitly name the database. If no input files are supplied, newhelp reads from the standard input stream, in which case the
-o flag must be given.
If the output file name is determined to be foo, newhelp will create foo.dir and foo.pag.
Although historically there have been multiple help text file formats, the only format currently supported using the -v option is version
2, and this is the default if no -v flag is provided.
The -V flag causes verbose messages to be printed while newhelp is parsing its input.
The first line of each entry in a help source file consists of an ``@'' character beginning the line followed by a space and then the per-
formance metric name and a one line description of the metric. Following lines (up to the next line beginning with ``@'' or end of file)
may contain a verbose help description. E.g.
#
# This is an example of newhelp's input syntax
#
@ kernel.all.cpu.idle CPU idle time
A cumulative count of the number of milliseconds
of CPU idle time, summed over all processors.
Three-part numeric metric identifiers (PMIDs) may be used in place of metric names, e.g. 60.0.23 rather than kernel.all.cpu.idle in the
example above. Other than for dynamic metrics (where the existence of a metric is known to a PMDA, but not visible in the PMNS and hence
has no name that could be known to newhelp) use of this syntactic variant is not encouraged.
Lines beginning with ``#'' are ignored, as are blank lines in the file before the first ``@''. The verbose help text is optional.
As a special case, a ``metric'' name of the form NNN.MM (for numeric NNN and MM) is interpreted as an instance domain identification, and
the text describes the instance domain.
FILES
$PCP_VAR_DIR/pmns/*
default PMNS specification files
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 configura-
tion file, as described in pcp.conf(5).
