NAME
pminfo - display information about performance metrics
SYNOPSIS
pminfo [-dfFIlLmMstTvVxz?] [-a archive] [-b batchsize] [-c dmfile] [--container name] [-h
hostname] [-K spec] [-[n|N] pmnsfile] [-O time] [-Z timezone] [metricname | pmid |
indom]...
DESCRIPTION
pminfo displays various types of information about performance metrics available through
the facilities of the Performance Co-Pilot (PCP).
The metrics of interest are named in the metricname arguments. If metricname is a non-
leaf node in the PMNS, then pminfo will recursively descend the PMNS and report on all
leaf nodes. If no metricname argument is given, the root of the PMNS is used.
If the metricname argument is in numeric dotted notation, it is interpreted as either a
3-dotted pmid (metric identifier - domain, cluster, item numbers) or a 2-dotted indom
(instance domain identifier - domain, serial number). In the pmid case, a reverse PMID-
to-name lookup is performed, and in the indom case, the instance domain is reported
directly. This latter mode can be used to report the instance domain ``one line'' and
long form help text summaries.
Unless directed to another host by the -h option, by default pminfo will contact the
Performance Metrics Collector Daemon (PMCD) on the local host. The connection to a PMCD
is only required if pminfo requires distributed PMNS information, and/or meta-data
describing metrics, and/or metric values, and/or help text.
The -a option causes pminfo to use the specified set of archives rather than connecting to
a PMCD.
The -L option causes pminfo to use a local context to collect metrics from PMDAs on the
local host without PMCD. Only some metrics are available in this mode.
The -a, -h and -L options are mutually exclusive.
OPTIONS
The available command line options are:
-a archive, --archive=archive
Performance metric values are retrieved from the set of Performance Co-Pilot (PCP)
archive log files identified by the archive argument, which is a comma-separated list
of names, each of which may be the base name of an archive or the name of a directory
containing one or more archives.
-b, --batch
This option may be used to define the maximum number of metrics to be fetched in a
single request for the -f and -v options. The default value for batchsize is 128.
-c dmfile, --derived=dmfile
The dmfile argument specifies a file that contains derived metric definitions in the
format described for pmLoadDerivedConfig(3). The -c option provides a way to load
derived metric definitions that is an alternative to the more generic use of the
PCP_DERIVED_CONFIG environment variable as described in PCPIntro(1). Using the -c
option and the PCP_DERIVED_CONFIG environment variable to specify the same
configuration is a bad idea, so choose one or the other method.
--container=container
Specify an individual container to be queried.
-d, --desc
Metric descriptions detailing the PMID, data type, data semantics, units, scale and
associated instance domain.
-f, --fetch
Fetch and print values for all instances. When fetching from a set of archives, only
those instances present in the first archive record for a metric will be displayed;
see also the -O option, else use pmdumplog(1) which may be a better tool for
examining archives.
-F, --fetchall
Same as -f but try harder to fetch instances for metrics which have non-enumerable
instance domains (e.g. metrics in the ``proc'' subtree of the default PMNS on some
platforms).
-h host, --host=host
Fetch performance metrics from pmcd(1) on host, rather than from the default
localhost.
-I, --fullindom
Print the InDom in verbose mode.
-K spec, --spec-local=spec
When using the -L/ option to fetch metrics from a local context, this option controls
the DSO PMDAs that should be made accessible. The spec argument conforms to the
syntax described in pmSpecLocalPMDA(3). More than one -K option may be used.
-l, --labels
Print label sets associated with metrics and instances. Labels are optional metric
metadata described in detail in pmLookupLabels(3).
-L, --local-PMDA
Use a local context to collect metrics from DSO PMDAs on the local host without PMCD.
See also -K.
-m, --pmid
Print the PMID in terse mode.
-M, --fullpmid
Print the PMID in verbose mode.
-n pmnsfile, --namespace=pmnsfile
Normally pminfo 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.
-N pmnsfile, --uniqnames=pmnsfile
The -N option supports the same function as -n, except for the handling of duplicate
names for the same Performance Metric Identifier (PMID) in pmnsfile - duplicate names
are allowed with -n but they are not allowed with -N.
-O time, --origin=time
When used in conjunction with an archive source of metrics and the options -f/, the
time argument defines a time origin at which the metrics should be fetched from the
set of archives. Refer to PCPIntro(1) for a complete description of this option, and
the syntax for the time argument.
-s, --series
Print time series identifiers associated with metrics, instances and sources. These
unique identifiers are calculated from intrinsic (non-optional) labels and other
metric metadata associated with each PMAPI context (sources), metrics and instances.
Archive, local context or pmcd(1) connections for the same host all produce the same
source identifier. See also pmLookupLabels(3) and the -l option.
-t, --oneline
Print the ``one line'' help summary, if available.
-T, --helptext
Print the help text, if available.
-v, --verify
Verify mode in which descriptions and values are retrieved, but only error conditions
are reported. This option silently disables any output from the options -f/--fetch,
-l/--labels, -I/--fullindom, -M/--fullpmid, -m/--pmid, -t/--oneline and
-T/--helptext.
-V, --version
Display version number and exit.
-x, --events
Like the -f/--fetch option, but with the additional functionality that if a value is
processed that is of type PM_TYPE_EVENT or PM_TYPE_HIGHRES_EVENT, then the event
records will be unpacked and the details of each event record reported.
-z, --hostzone
Change the reporting timezone to the local timezone at the host that is the source of
the performance metrics, as identified via either the -h or -a options.
-Z timezone, --timezone=timezone
By default, pminfo reports the time of day according to the local timezone on the
system where pminfo 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.
FILES
$PCP_VAR_DIR/pmns/*
default local PMNS specification files
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).
For environment variables affecting PCP tools, see pmGetOptions(3).
