pmdumplog(1)

NAME
     pmdumplog - dump internal details of a performance metrics archive log

SYNOPSIS
     pmdumplog [-adiLlmrstz] [-n pmnsfile] [-S starttime] [-T endtime] [-Z
     timezone] archive [metricname ...]
     pmdumplog [-v file]

DESCRIPTION
     pmdumplog dumps assorted control, metadata, index and state information
     from the files of a Performance Co-Pilot (PCP) archive log.  The archive
     log has the base name archive and must have been previously created using
     pmlogger(1).

     Normally pmdumplog operates on the distributed Performance Metrics Name
     Space (PMNS), however if the -n option is specified an alternative local
     PMNS is loaded from the file pmnsfile.

     If any metricname arguments appear, the report will be restricted to
     information relevant to the named performance metrics.  If metricname is
     a non-leaf node in the namespace (see pmns(4)), then pmdumplog will
     recursively descend the archive's namespace and report on all leaf nodes.

     The options control the specific information to be reported.

     -a   Report everything, i.e. the flags -d, -i, -l, -m, -s and -t.

     -d   Display the metadata and descriptions for those performance metrics
          that appear at least once in the archive:  see pmLookupDesc(3) for
          more details on the metadata describing metrics.

     -i   Display the instance domains, and any variations in their instance
          members over the duration of the archive: see pmGetInDom(3) for more
          details on instance domains.

     -l   Dump the archive label, showing the log format version, the time and
          date for the start and (current) end of the archive, and the host
          from which the performance metrics values were collected.

     -L   Like -l, just a little more verbose.

     -m   Print the values for the performance metrics from the archive.  This
          is the default display option.

          Metrics without an instance domain are reported as:
            [timestamp] metric-id (metric-name): value value

          Metrics with an instance domain are reported as:
            [timestamp] metric-id (metric-name):
                inst [internal-id or "external-id"] value value
          The timestamp is only reported for the first metric in a group of
          metrics sharing the same timestamp.

     -r   Process the archive in reverse order, from most recent to oldest
          recorded metric values.

     -S   When using the -m option, the report will be restricted to those
          records logged at or after starttime.  Refer to PCPIntro(1) for a
          complete description of the syntax for starttime.

     -s   Report the size in bytes of each physical record in the archive.

     -T   When using the -m option, the report will be restricted to those
          records logged before or at endtime.  Refer to PCPIntro(1) for a
          complete description of the syntax for endtime.

     -t   Dump the temporal index that is used to provide accelerated access
          to large archive files.

          The integrity of the index will also be checked.  If the index is
          found to be corrupted, the ``*.index'' file can be renamed or
          removed and the archive will still be accessible, however retrievals
          may take longer without the index.  Note however that a corrupted
          temporal index is usually indicative of a deeper malaise that may
          infect all files in a PCP archive.

     -v   Verbose mode.  Dump the records from a physical archive file in
          hexadecimal format.  In this case file is the name of a single file,
          usually a basename (as would otherwise appear as the archive command
          line argument), concatenated with ``.'' followed by one of meta (the
          metadata), index (the temporal index), or a digit (one of the
          volumes of metric values).

          Use of -v precludes the use of all other options and arguments.

     By default, pmdumplog reports the time of day according to the local
     timezone on the system where pmdumplog is run.  The -Z option changes the
     timezone to timezone in the format of the environment variable TZ as
     described in environ(5).  The -z option changes the timezone to the local
     timezone at the host that is the source of the performance metrics, as
     specified in the label record of the archive log.

FILES
     $PCP_VAR_DIR/pmns/*
               default local PMNS specification files
     $PCP_LOG_DIR/pmloggerhostname
               Default directory for PCP archives containing performance
               metric values collected from the host hostname.

PCP ENVIRONMENT
     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(4).
