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(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 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): 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 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 com-
	    plete 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/pmlogger/hostname
		 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 configura-
       tion file, as described in pcp.conf(5).
