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).
