PMLOGSIZE(1)               General Commands Manual              PMLOGSIZE(1)

NAME         top

       pmlogsize - report sizes for parts of PCP archive(s)

SYNOPSIS         top

       pmlogsize [-drv?]  [-x threshold] archive [...]

DESCRIPTION         top

       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

       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.

OPTIONS         top

       The available command line options are:

       -d, --detail
            Enable detailed reporting.  This means space per instance domain
            in a metadata file and space per metric (for values) in a data

       -r, --replication
            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.

       -v, --verbose
            Enable verbose mode.  This option can be provided more than once
            for additional verbosity.

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

DIAGNOSTICS         top

       All are generated on standard error and are intended to be self-


       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).
