NAME

       pmlogger_rewrite - helper script to rewrite Performance Co-Pilot archives

SYNOPSIS

       $PCP_BINADM_DIR/pmlogger_rewrite [-dNsVvw?]  [-c config] archive ...

DESCRIPTION

       pmlogger_rewrite  is  a  helper  script  that  is used by pmlogger_daily(1) when rewriting
       Performance Co-Pilot  (PCP)  archives.   Rewriting  is  usually  required  to  accommodate
       evolutionary  changes  in  metadata  so  old  archives can be updated and then merged with
       current archives.

       pmlogger_rewrite is a wrapper script for pmlogrewrite(1) that will potentially rewrite all
       of  the  archives  matching  the  archive  arguments.   Each archive argument may be a PCP
       archive file name, the basename for the files in a PCP archive, or a directory  (in  which
       case all subordinate PCP archives are found by recursive descent).

       pmlogrewrite  is  run with the -i option so rewriting is done ``in place''.  The -q option
       is also used, so if no rewriting is required then no  changes  are  made  to  the  archive
       files.

OPTIONS

       The  following  options  are  passed  through  to  pmlogrewrite:  -c (or --config), -d (or
       --desperate), -s (or --scale), -v  (or  --verbose)  and  -w  (or  --warnings).   Refer  to
       pmlogrewrite(1) for the meaning of these options.

       The remaining options are:

       -N, --showme
            Runs pmlogger_rewrite in a ``show me'' or ``dry run'' mode where the tasks that would
            be performed are reported, but no changes are  made.   This  is  typically  used  for
            debugging in combination with one (verbose) or two (very verbose) -V options.

       -V, --verbose
            Increase script output verbosity.

       -?, --help
            Display usage message and exit.

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).
