DESCRIPTION

       pcp2xlsx  is  a  customizable  performance  metrics  exporter  tool from PCP to XLSX.  Any
       available performance metric, live or archived, system and/or application, can be selected
       for exporting using either command line arguments or a configuration file.

       pcp2xlsx  is  a  close  relative  of  pmrep(1).   Refer  to  pmrep(1)  for  the metricspec
       description accepted on pcp2xlsx command line.  See pmrep.conf(5) for description  of  the
       pcp2xlsx.conf  configuration  file  syntax.  This page describes pcp2xlsx specific options
       and configuration file differences with pmrep.conf(5).  pmrep(1)  also  lists  some  usage
       examples of which most are applicable with pcp2xlsx as well.

       Only  the  command line options listed on this page are supported, other options available
       for pmrep(1) are not supported.

       Options via environment values (see pmGetOptions(3)) override the  corresponding  built-in
       default   values   (if  any).   Configuration  file  options  override  the  corresponding
       environment  variables  (if  any).   Command  line  options  override  the   corresponding
       configuration file options (if any).

CONFIGURATION FILE

       pcp2xlsx  uses a configuration file with syntax described in pmrep.conf(5).  The following
       options are common with pmrep.conf: version, source, speclocal, derived, header,  globals,
       samples, interval, type, type_prefer, ignore_incompat, names_change, instances, omit_flat,
       include_labels, precision, precision_force, count_scale,  count_scale_force,  space_scale,
       space_scale_force,  time_scale,  time_scale_force.  The rest of the pmrep.conf options are
       recognized but ignored for compatibility.

   pcp2xlsx specific options
       None.

OPTIONS

The available command line options are:

-0 precision, --precision-force=precision
Like -P but this option will override per-metric specifications.

-4 action, --names-change=action
Specify which action to take on receiving a metric names change event during
sampling. These events occur when a PMDA discovers new metrics sometime after
starting up, and informs running client tools like pcp2xlsx. Valid values for action
are update (refresh metrics being sampled), ignore (do nothing - the default
behaviour) and abort (exit the program if such an event occurs).

-5, --ignore-unknown
Silently ignore any metric name that cannot be resolved. At least one metric must be
found for the tool to start.

-a archive, --archive=archive
Performance metric values are retrieved from the set of Performance Co-Pilot (PCP)
archive 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.

-A align, --align=align
Force the initial sample to be aligned on the boundary of a natural time unit align.
Refer to PCPIntro(1) for a complete description of the syntax for align.

--archive-folio=folio
Read metric source archives from the PCP archive folio created by tools like
pmchart(1) or, less often, manually with mkaf(1).

-b scale, --space-scale=scale
Unit/scale for space (byte) metrics, possible values include bytes, Kbytes, KB,
Mbytes, MB, and so forth. This option will not override possible per-metric
specifications. See also pmParseUnitsStr(3).

-B scale, --space-scale-force=scale
Like -b but this option will override per-metric specifications.

-c config, --config=config
Specify the config file or directory to use. In case config is a directory all files
in it ending .conf will be included. The default is the first found of:
./pcp2xlsx.conf, $HOME/.pcp2xlsx.conf, $HOME/pcp/pcp2xlsx.conf, and
$PCP_SYSCONF_DIR/pcp2xlsx.conf. For details, see the above section and
pmrep.conf(5).

--container=container
Fetch performance metrics from the specified container, either local or remote (see
-h).

-C, --check
Exit before reporting any values, but after parsing the configuration and metrics and
printing possible headers.

--daemonize
Daemonize on startup.

-e derived, --derived=derived
Specify derived performance metrics. If derived starts with a slash (``/'') or with
a dot (``.'') it will be interpreted as a PCP derived metrics configuration file,
otherwise it will be interpreted as comma- or semicolon-separated derived metric
expressions. For complete description of derived metrics and PCP derived metrics
configuration files see pmLoadDerivedConfig(3) and pmRegisterDerived(3).
Alternatively, using pmrep.conf(5) configuration syntax allows defining derived
metrics as part of metricsets.

-G, --no-globals
Do not include global metrics in reporting (see pmrep.conf(5)).

-f format, --timestamp-format=format
Use the format string for formatting the timestamp. The format will be used with
Python's datetime.strftime method which is mostly the same as that described in
strftime(3). The default is %Y-%m-%d %H:%M:%S.

-F outfile, --output-file=outfile
Specify the output file outfile.

-h host, --host=host
Fetch performance metrics from pmcd(1) on host, rather than from the default
localhost.

-H, --no-header
Do not print any headers.

-i instances, --instances=instances
Retrieve and report only the specified metric instances from currently present metric
instances. By default all current instances are reported.

Refer to pmrep(1) for complete description of this option.

-I, --ignore-incompat
Ignore incompatible metrics. By default incompatible metrics (that is, their type is
unsupported or they cannot be scaled as requested) will cause pcp2xlsx to terminate
with an error message. With this option all incompatible metrics are silently
omitted from reporting. This may be especially useful when requesting non-leaf nodes
of the PMNS tree for reporting.

-K spec, --spec-local=spec
When fetching metrics from a local context (see -L), the -K option may be used to
control 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, --local-PMDA
Use a local context to collect metrics from DSO PMDAs on the local host without PMCD.
See also -K.

-m, --include-labels
Include PCP metric labels in the output.

-O origin, --origin=origin
When reporting archived metrics, start reporting at origin within the time window
(see -S and -T). Refer to PCPIntro(1) for a complete description of the syntax for
origin.

-P precision, --precision=precision
Use precision for numeric non-integer output values. The default is to use 3 decimal
places (when applicable). This option will not override possible per-metric
specifications.

-q scale, --count-scale=scale
Unit/scale for count metrics, possible values include count x 10^-1, count, count x
10, count x 10^2, and so forth from 10^-8 to 10^7. (These values are currently
space-sensitive.) This option will not override possible per-metric specifications.
See also pmParseUnitsStr(3).

-Q scale, --count-scale-force=scale
Like -q but this option will override per-metric specifications.

-r, --raw
Output raw metric values, do not convert cumulative counters to rates. This option
will override possible per-metric specifications.

-R, --raw-prefer
Like -r but this option will not override per-metric specifications.

-s samples, --samples=samples
The samples argument defines the number of samples to be retrieved and reported. If
samples is 0 or -s is not specified, pcp2xlsx will sample and report continuously (in
real time mode) or until the end of the set of PCP archives (in archive mode). See
also -T.

-S starttime, --start=starttime
When reporting archived metrics, 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 interval, --interval=interval
Set the reporting interval to something other than the default 1 second. The
interval argument follows the syntax described in PCPIntro(1), and in the simplest
form may be an unsigned integer (the implied units in this case are seconds). See
also the -T option.

-T endtime, --finish=endtime
When reporting archived metrics, 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.

When used to define the runtime before pcp2xlsx will exit, if no samples is given
(see -s) then the number of reported samples depends on interval (see -t). If
samples is given then interval will be adjusted to allow reporting of samples during
runtime. In case all of -T, -s, and -t are given, endtime determines the actual time
pcp2xlsx will run.

-v, --omit-flat
Report only set-valued metrics with instances (e.g. disk.dev.read) and omit single-
valued ``flat'' metrics without instances (e.g. kernel.all.sysfork). See -i and -I.

-V, --version
Display version number and exit.

-y scale, --time-scale=scale
Unit/scale for time metrics, possible values include nanosec, ns, microsec, us,
millisec, ms, and so forth up to hour, hr. This option will not override possible
per-metric specifications. See also pmParseUnitsStr(3).

-Y scale, --time-scale-force=scale
Like -y but this option will override per-metric specifications.

-z, --hostzone
Use the local timezone of the host that is the source of the performance metrics, as
identified by either the -h or the -a options. The default is to use the timezone of
the local host.

-Z timezone, --timezone=timezone
Use timezone for the date and time. Timezone is in the format of the environment
variable TZ as described in environ(7). Note that when including a timezone string
in output, ISO 8601 -style UTC offsets are used (so something like -Z EST+5 will
become UTC-5).

-?, --help
Display usage message and exit.

FILES

       pcp2xlsx.conf
            pcp2xlsx configuration file (see -c)

       $PCP_SYSCONF_DIR/pmrep/*.conf
            system provided default pmrep configuration 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).
