       pmdumplog - dump internal details of a performance metrics archive log


       pmdumplog  [-adilLmMrstxz] [-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),
       however  if  the  -n option is specified an alternative local PMNS is loaded from the file

       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.

       -M   If no metricname is specified then <mark> records are reported when they are found in
            the  archive.   If  metricname  arguments  are specified, then <mark> records are not
            reported by default.  The -M option forces <mark> records to be reported,  even  when
            metricname arguments are specified.

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

       -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
            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.

       -x   Extended  timestamp  reporting  format  that includes the day of the week, day of the
            month, month and year in addition to the (default) hours, minutes and  seconds  time.
            This is useful for archives that span multiple days.

            A  second -x option will also report the timestamp as an offset from the start of the
            archive in units of seconds.  This is useful in conjunction  with  debug  diagnostics
            from the archive handling routines in libpcp.

       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(7).  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.


                 default local PMNS specification files
                 Default   directory  for  PCP  archives  containing  performance  metric  values
                 collected from the host hostname.


       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).
