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
values.
-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 values.
-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
starttime.
-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.
-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.
