NAME         top

       pmlogger_merge - helper script to merge Performance Co-Pilot
       archives

SYNOPSIS         top

       $PCP_BINADM_DIR/pmlogger_merge [-fNVE?]  [input-basename ...
       output-name]

DESCRIPTION         top

       pmlogger_merge is a helper script that is used by
       pmlogger_daily(1) when merging all of the Performance Co-Pilot
       (PCP) archives for a single host on a single day into a combined
       PCP archive.

       pmlogger_merge is a wrapper script for pmlogextract(1) that
       merges all of the archive logs matching the input-basename
       arguments, and creates a new archive using output-name as the
       base name for the physical files that constitute an archive log.
       The input-basename arguments may contain meta characters in the
       style of sh(1).

OPTIONS         top

       The available command line options are:

       -f, --force
            This option causes all of the input files to be removed once
            the output archive has been created.

       -N, --showme
            Runs pmlogger_merge 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 verbosity in the output progress report.

       -E, --expunge
            When metric metadata differences are encountered between
            archives to be merged, the default behaviour is for
            pmlogger_merge to fail with a fatal error and the output-
            name archive is not created.  The -E flag instead issues a
            warning and excludes the affected metrics from the merged
            output archive.  This is intended for automated daily log
            rotation where it is highly desirable for unattended daily
            archive merging, rewriting and compression to succeed.  See
            also pmlogger_daily(1) and the -x flag to pmlogextract(1).

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

PCP ENVIRONMENT         top

       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).
