CHKHELP(1) General Commands Manual CHKHELP(1)
chkhelp - check performance metrics help text files
$PCP_BINADM_DIR/chkhelp [-eHiOp] [-n pmnsfile] [-v version] helpfile
[metricname ...]
chkhelp checks the consistency of Performance Co-Pilot help text
files generated by newhelp(1) and used by Performance Metric Domain
Agents (PMDAs). The checking involves scanning the files, and
optionally displaying selected entries.
The files helpfile.dir and helpfile.pag are created by newhelp(1),
and are assumed to already exist.
Without any options or metricname arguments, chkhelp silently
verifies the structural integrity of the help files.
If any metricname arguments are specified, then the help entries for
only the corresponding metrics will be processed.
If no metricname arguments are specified, then at least one of the
options -i or -p must be given. The -i option causes entries for all
instance domains to be processed (ignoring entries for performance
metrics). The -p option causes entries for all metrics to be
displayed (ignoring entries for instance domains).
When metric entries are to be processed (via either the metricname
arguments or the -p option or the -i option), the -O and -H options
request the display of the one-line and verbose help text
respectively. The default is -O.
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.
Normally chkhelp operates on the default Performance Metrics Name
Space (PMNS), however if the -n option is specified an alternative
namespace is loaded from the file pmnsfile.
The -e option provides an existence check where all of the specified
metrics from the PMNS (note, not from helpfile) are scanned, and only
the names of the metrics for which no help text exists are reported.
The -e option is mutually exclusive with the -i and/or -p options.
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).
newhelp(1), PMAPI(3), pmLookupInDomText(3), pmLookupText(3),
pcp.conf(5) and pcp.env(5).
There are all sorts of reasons a help database may be inconsistent,
the most likely is that a performance metric in the database is not
defined in the loaded PMNS.
