NAME
pmdumplog - dump internal details of a performance metrics archive log
SYNOPSIS
pmdumplog [-adehilLmMrstxz] [-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 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 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 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 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 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.
-M 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.
-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.
-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.
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). 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).
