       pmlogcheck - checks for invalid data in a PCP archive

       pmlogcheck [-lz] [-n pmnsfile] [-S start] [-T finish] [-Z timezone] archive

       pmlogcheck  prints  information about the nature of any invalid data which it detects in a
       PCP archive.  Of particular interest are wrapped values for metrics which are expected  to
       have monotonically increasing values.  The archive has the base name archive and must have
       been previously created using pmlogger(1).

       Normally pmlogcheck operates on the default Performance Metrics Namespace (pmns(5)),  how-
       ever  if the -n option is specified an alternative namespace is loaded from the file pmns-

       The command line options -S and -T can be used to specify a time window over which metrics
       should be summarized.  These options are common to many Performance Co-Pilot tools and are
       fully described in PCPIntro(1).

       The -l option prints 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.

       By default, pmlogcheck reports the time of day according to the local timezone on the sys-
       tem where pmlogcheck 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.

       For each metric having ``counter'' semantics (i.e. the  metric  is  expected  to  increase
       monotonically)  which  has  been  detected as having wrapped at some point in the archive,
       pmlogcheck produces output describing the metric name  (with  instance  identifiers  where
       appropriate), the internal storage type for the metric, the value of the metric before the
       counter wrap (with its associated timestamp), and the value of the metric after	the  wrap
       (also with a timestamp).

       pmlogcheck  produces two different timestamp formats, depending on the interval over which
       it is run.  For an interval greater than 24 hours, the date is displayed  in  addition  to
       the  time  at which the counter wrap occurred.  If the extent of the data being checked is
       less than 24 hours, a more precise format is used (time is displayed with millisecond pre-
       cision, but without the date).

       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 config-
       uration file, as described in pcp.conf(5).

       pmval(1), pcp.conf(5), pcp.env(5) and pmns(5).

       All are generated on standard error and are intended to be self- explanatory.
