NAME         top

       pmlogger_rewrite - helper script to rewrite Performance Co-Pilot
       archives

SYNOPSIS         top

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

DESCRIPTION         top

       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         top

       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 op‐
            tions.

       -V, --verbose
            Increase script output verbosity.

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

PCP ENVIRONMENT         top

       Environment variables with the prefix PCP_ are used to parameter‐
       ize the file and directory names used by PCP.  On each installa‐
       tion, the file /etc/pcp.conf contains the local values for these
       variables.  The $PCP_CONF variable may be used to specify an al‐
       ternative configuration file, as described in pcp.conf(5).
