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 archive logs 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.
The following options are passed through to pmlogrewrite: -c, -d,
-s, -v and -w. Refer to pmlogrewrite(1) for the meaning of these
The remaining options are:
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
Increase script output verbosity.
Display usage message and exit.
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
