       pmdumplog - dump internal details of a performance metrics archive log


       pmdumplog  [-adehIilLmMrstxzV?]   [-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.

       Command line options control the specific information to be reported.


       The available command line options are:

       -a, --all
            Report  almost  everything,  i.e.  the flags -d, -i, -L, -m, -s and -t.  The optional
            help text (-h) and label metadata strings (-e) are not reported by default.

       -d, --descs
            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.

       -e, --labelsets
            Display the label metadata if it is present in the  archive.   See  pmLookupLabels(3)
            for more details on the label metadata hierarchy associated with metrics.

       -h, --helptext
            Display  metric  and  instance  domain  help  text  if  present  in the archive.  See
            pmLookupText(3) for more details on the help text associated with metrics.

       -i, --insts
            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.

       -I, --on-disk-insts
            Display  the  on-disk instance domains, which may use a different format and encoding
            than the one visible above the Performance Metrics Programming Interface (PMAPI) when
            using  pmGetInDom(3)  and  related  routines.  The on-disk format is only of interest
            when investigating the internal structure of PCP archives.

       -l, --label
            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, --metrics
            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, --markrecs
            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.

            <mark>  records  are inserted into a PCP archive log by pmlogger(1), pmlogextract(1),
            and similar tools to indicate a temporal discontinuity in the time-series  of  metric

       -n pmnsfile, --namespace=pmnsfile
            Load an alternative Performance Metrics Name Space (PMNS(5)) from the file pmnsfile.

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

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

       -S starttime, --start=starttime
            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

       -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.

       -T endtime, --finish=endtime
            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.

       -v file
            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.

       -V, --version
            Display version number and exit.

       -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.

       -z, --hostzone
            Change  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.

       -Z timezone, --timezone=timezone
            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).

       -?, --help
            Display usage message and exit.


            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).
