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(4)), 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): value value

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

            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(4).
