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 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/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
       configuration file, as described in pcp.conf(5).
