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 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.

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 file.

       -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.

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).
