       pmdumplog - dump internal details of a performance metrics archive log

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

       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), how-
       ever if the -n option is specified an alternative local PMNS is loaded from the file pmns-

       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(5)), 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 met-
	    rics 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): value1 value2

	    Metrics with an instance domain are reported as:
	      [timestamp] metric-id (metric-name):
		  inst [internal-id or "external-id"] value1 value2

	    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 val-

       -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

       -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

	    The integrity of the index will also be checked.  If the index is found  to  be  cor-
	    rupted,  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 other-
	    wise 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  sys-
       tem  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.

       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 config-
       uration file, as described in pcp.conf(5).
