       chkhelp - check performance metrics help text files


       $PCP_BINADM_DIR/chkhelp [-eHiOp?]  [-n pmnsfile] 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.

       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


       The available command line options are:

       -e   Report metrics with no help text.

       -H   Display verbose help text and exit.

       -i   Process all the instance domains.

       -n pmnsfile
            Load an alternative Performance Metrics Name Space (PMNS(5)) from the file pmnsfile.

       -O   Display the one line help summary.

       -p   Process all the metrics (PMIDs).

       -?   Display usage message and exit.


       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.


       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).

       For environment variables affecting PCP tools, see pmGetOptions(3).
