pmlogger_merge — helper script to merge Performance Co-Pilot archives
$PCP_BINADM_DIR/pmlogger_merge [-fNV] [input-basename ... output-name]
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).
If specified, the -f option causes all of the input files to be removed once the output archive has been created.
Using -N option 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.
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).
