pmlogsize prints information about the size of the index,
metadata and data sections of a Performance Co-Pilot (PCP)
archive. The output is intended to guide improvements in archive
encoding format for PCP developers and to help trim pmlogger(1)
configuration files to remove metrics that are bloating the PCP
archives with low-value data in production environments.
The archive arguments can be any mixture of the names of the
physical files of a PCP archive or the basename that is common to
all the component physical files in a single archive. In the
latter case archive is replaced by a list of all of the matching
component file names.
Note the semantics is a little different to other PCP tools in
that foo.meta means just the file foo.meta, not foo.index,
foo.meta, foo.0, etc.
The available command line options are:
Enable detailed reporting. This means space per instance
domain in a metadata file and space per metric (for values)
in a data file.
Display additional information about possible replicated
values in the data file and replicated instances in the
metadata file. This option implies -d.
-x threshold, --threshold=threshold
With -d (or -r), cut off the report after at least threshold
percent of the associated space (metric values or instance
domains) has been reported. The default behaviour is
equivalent to threshold being set to 100.
Enable verbose mode. This option can be provided more than
once for additional 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
