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 options.
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 pcp.conf(5).
