SYNOPSIS

10       [metricname ...]

DESCRIPTION

13       chkhelp checks the consistency of Performance Co-Pilot help text  files
14       generated  by  newhelp(1)  and used by Performance Metric Domain Agents
15       (PMDAs).  The checking involves scanning the files, and optionally dis‐
16       playing selected entries.
17
18       The  files helpfile.dir and helpfile.pag are created by newhelp(1), and
19       are assumed to already exist.
20
21       Without any options or metricname arguments, chkhelp silently  verifies
22       the structural integrity of the help files.
23
24       If  any  metricname  arguments are specified, then the help entries for
25       only the corresponding metrics will be processed.
26
27       If no metricname arguments are specified, then  at  least  one  of  the
28       options  -i  or -p must be given.  The -i option causes entries for all
29       instance domains to be processed (ignoring entries for performance met‐
30       rics).   The  -p  option causes entries for all metrics to be displayed
31       (ignoring entries for instance domains).
32
33       When metric entries are to be  processed  (via  either  the  metricname
34       arguments  or  the  -p  option or the -i option), the -O and -H options
35       request the display of the one-line and verbose help text respectively.
36       The default is -O.
37
38       Although  historically there have been multiple help text file formats,
39       the only format currently supported using the -v option is  version  2,
40       and this is the default if no -v flag is provided.
41
42       Normally  chkhelp operates on the default Performance Metrics Namespace
43       (PMNS), however if the -n option is specified an alternative  namespace
44       is loaded from the file pmnsfile.

PCP ENVIRONMENT

47       Environment variables with the prefix PCP_ are used to parameterize the
48       file and directory names used by PCP.  On each installation,  the  file
49       /etc/pcp.conf  contains  the  local  values  for  these variables.  The
50       $PCP_CONF variable may be used to specify an alternative  configuration
51       file, as described in pcp.conf(4).

DIAGNOSTICS

58       There are all sorts of reasons a help database may be inconsistent, the
59       most likely is that a performance metric in the database is not defined
60       in the loaded PMNS.
