Any available performance metric, live or archived, system and/or application, can be selected for reporting using one of the output alternatives listed below together with applicable formatting options. **pmrep** collects selected metric values through the facilities of the Performance Co-Pilot (PCP), see [**PCPIntro**(1)](/PCPIntro/1.md). The metrics to be reported are specified on the command line, in configuration files, or both. Metrics can be automatically converted and scaled using the PCP facilities, either by default or by per-metric scaling specifications. In addition to the existing metrics, derived metrics can be defined using the arithmetic expressions described in [**pmRegisterDerived**(3)](/pmRegisterDerived/3.md). A wide range of metricsets (see below) is included by default, providing reports on per-process details, NUMA performance, mimicking other tools like **[sar(1)](/sar/1.md)** and more, see the **pmrep** configuration files in *$PCP\_SYSCONF\_DIR/pmrep* (typically */etc/pcp/pmrep*) for details. Tab completion for options, metrics, and metricsets is available for bash and zsh. Unless directed to another host by the **-h** option, **pmrep** will contact the Performance Metrics Collector Daemon (PMCD, see [**pmcd**(1)](/pmcd/1.md)) on the local host. The **-a** option causes **pmrep** to use the specified set of archives rather than connecting to a PMCD. The **-a** and **-h** options are mutually exclusive. The **-L** option causes **pmrep** to use a local context to collect metrics from DSO PMDAs (Performance Metrics Domain Agents, \`\`plugins'') on the local host without PMCD. Only some metrics are available in this mode. The **-a**, **-h**, and **-L** options are mutually exclusive. The metrics of interest are named in the *metricspec* argument(s). If a metricspec specifies a non-leaf node in the Performance Metrics Name Space (PMNS), then **pmrep** will recursively descend the PMNS and report on all leaf nodes (i.e. metrics) for that metricspec. Use [**pminfo**(1)](/pminfo/1.md) to list all the metrics (PMNS lead nodes) and their descriptions. A *metricspec* has three different forms. First, on the command line it can start with a colon (\`\`:'') to indicate a *metricset* to be read from **pmrep** configuration files (see **-c** and [**pmrep.conf**(5)](/pmrep.conf/5.md)), which may then consist of any number of metrics. Second, a *metricspec* starting with non-colon specifies a PMNS node as described above, optionally followed by metric output formatting definitions. This so-called *compact form* of a metricspec is defined as follows: ``` metric[,label[,instances[,unit/scale[,type[,width[,precision[,limit]]]]]]] ``` A valid PMNS node (*metric*) is mandatory. It may be followed by a text *label* used with *stdout* output. The optional *instances* definition restricts *csv* and *stdout* reporting to the specified instances of the metric so non-matching instances will be filtered out (see **-i**). An optional *unit/scale* is applicable for dimension-compatible, non-string metrics. See below for supported *unit/scale* specifications. By default, cumulative counter metrics are converted to rates, an optional *type* can be set to **raw** to disable this rate conversion. For *stdout* output a numeric *width* can be used to set the width of the output column for this metric. Too wide strings in the output will be truncated to fit the column. A metric-specific *precision* can be provided for numeric non-integer output values. Lastly, a metric-specific *limit* can be set for filtering out numeric values per the limit. As a special case for metrics that are counters with time units (nanoseconds to hours), the *unit/scale* can be used to change the default reporting (for example, milliseconds / second) to normalize to the range zero to one by setting this to **sec** (see also **-y** and **-Y**). The following *metricspec* requests the metric **kernel.all.sysfork** to be reported under the text label **forks**, converting to the metric default rate count/s in an **8** wide column. Although the definitions in this *compact form* are optional, they must always be provided in the order specified above, thus the commas. ``` kernel.all.sysfork,forks,,,,8 ``` The third form of a metricspec, *verbose form*, is described and valid only in [**pmrep.conf**(5)](/pmrep.conf/5.md). Derived metrics are specified like regular PMNS leaf node metrics. Options via environment values (see [**pmGetOptions**(3)](/pmGetOptions/3.md)) 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). **pcp2csv** is an alias for **pmrep**. ## OPTIONS The available command line options are: - **-0** *precision*, **--precision-force**=*precision* Like **-P** but this option *will* override per-metric specifications. - **-1**, **--dynamic-header** Print a new dynamically adjusted header every time changes in the availability of metric and instance values occur. By default a static header that never changes is printed once. See also **-4**, **-7**, and **-E**. - **-2**, **--overall-rank** Perform overall ranking of instances in archive. By default ranking (see **-J**) and reporting happens on each interval. With this option all instances and values are ranked before a summary is reported. See [**pmlogsummary**(1)](/pmlogsummary/1.md) for further archive summary reporting alternatives, including averages and peak times for values. - **-3**, **--overall-rank-alt** Like **-2** but print metric instances in **pmrep** *metricspec* format, to allow easily selecting the instances for further investigation. - **-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 **pmrep**. 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). *update* implies **--dynamic-header**. - **-5**, **--ignore-unknown** A metric that **pmrep** is asked to report may be \`\`unknown'' for a number of reasons: the metric is not in the PMNS of the requested source of metrics ([**pmcd**(1)](/pmcd/1.md) for live metrics from a host, or a PCP archive for historical metrics), or one or more operand metrics in a derived metric definition is not available, or a derived metric definition contains syntax errors. By default, **pmrep** will report errors and exit if **any** requested metric is unknown. The **-5** option changes the default behaviour and **pmrep** will silently ignore any metric that is unknown, provided at least one known metric remains to be reported. If an unknown metric is associated with a derived metric definition, refer to [**pmRegisterDerivedMetric**(3)](/pmRegisterDerivedMetric/3.md) for a deeper explanation of derived metrics and the options available for diagnosing issues with their definition and evaluation. - **-6**, **--sort-metric**=*sort-metric* Specify a sort reference metric to sort output by values with **-X**. By default sorting order is descending, prepending the metric name with the minus sign (\`\`-'') will change the order to be ascending. See also **-J** and **-N**. - **-7**, **--fixed-header** With **-X** print a fixed header once (unless using **-E**) including all metrics being reported. Unlike with the default (static) header, only instances with values available are reported. Unlike with the dynamic header, the header is not updated even if values for some metrics later become (un)available. See also **-1** and **-E**. - **-8** *limit*, **--limit-filter**=*limit* Limit results to instances with values above/below *limit*. A positive integer will include instances with values at or above the limit in reporting. A negative integer will include instances with values at or below the limit in reporting. A value of zero performs no limit filtering. This option will *not* override possible per-metric specifications. See also **-J** and **-N**. - **-9** *limit*, **--limit-filter-force**=*limit* Like **-8** but this option *will* override per-metric specifications. - **-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. See also **-u**. - **-A** *align*, **--align**=*align* Force the initial sample to be aligned on the boundary of a natural time unit *align*. Refer to [**PCPIntro**(1)](/PCPIntro/1.md) 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)](/pmchart/1.md) or, less often, manually with [**mkaf**(1)](/mkaf/1.md). - **-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)](/pmParseUnitsStr/3.md). - **-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: *./pmrep.conf*, *$HOME/.pmrep.conf*, *$HOME/pcp/pmrep.conf*, *$PCP\_SYSCONF\_DIR/pmrep/pmrep.conf*, and *$PCP\_SYSCONF\_DIR/pmrep*. See [**pmrep.conf**(5)](/pmrep.conf/5.md). - **--container**=*container* Fetch performance metrics from the specified *container*, either local or remote (see **-h**). - **--csv-unit-info** Append unit strings to metric names in the CSV header using the form *metric(unit)* or *metric\[inst\](unit)*. See also **-k**. - **-C**, **--check** Exit before reporting any values, but after parsing the configuration and metrics and printing possible headers. - **-d**, **--delay** When replaying from an archive, this option requests that the prevailing real-time delay be applied between samples (see **-t**) to effect a pause, rather than the default behaviour of replaying at full speed. - **--daemonize** Daemonise 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)](/pmLoadDerivedConfig/3.md) and [**pmRegisterDerived**(3)](/pmRegisterDerived/3.md). Alternatively, using [**pmrep.conf**(5)](/pmrep.conf/5.md) configuration syntax allows defining derived metrics as part of metricsets. In case of issues with derived metrics, review the aforementioned manual pages in detail and ensure all the required metrics are available, especially when using archives. Use **-Dderive** to see additional debug information about parsing and evaluating derived metrics. - **-E** *lines*, **--repeat-header**=*lines* Repeat the header every *lines* of output. When not using **-1** or **-7** use **auto** to repeat the header based on terminal height. See also **-1** and **-7**. - **-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)](/strftime/3.md). An empty *format* string (i.e. "") will remove the timestamps from the output. Defaults to **%H:%M:%S** when using the *stdout* output target. Defaults to **%Y-%m-%d %H:%M:%S** when using the *csv* output target. - **-F** *outfile*, **--output-file**=*outfile* Specify the output file *outfile*. See **-o**. - **-g**, **--separate-header** Output the column number and complete metric information, one-per-line, before printing the metric values. - **-G**, **--no-globals** Do not include global metrics in reporting (see [**pmrep.conf**(5)](/pmrep.conf/5.md)). - **-h** *host*, **--host**=*host* Fetch performance metrics from [**pmcd**(1)](/pmcd/1.md) 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*. By default all initially present instances are reported, except when writing an archive (see **-o**), where also all future instances will be reported. The specified *instances* are filtered from the initially present instances when the tool is starting up. Thus instances which would match the filter appearing after the tool has started up will not be reported, use **-j** to change this. This is a global option that is used for all set-valued metrics unless a metric-specific instance filter is provided as part of a *metricspec*. By default single-valued \`\`flat'' metrics without instances are still reported as usual, use **-v** to change this. *instances* is a comma-separated list of one or more instance filter specifications. Filters containing commas or whitespace must be quoted with single (') or double (") quotes. Note that as part of a *metricspec* on command line a list with more than one filter both the list and each filter must be quoted as shown below. It is also possible to define a single filter with bars (\|) as instance separating regex in order to make quoting easier, see below. Multiple **-i** options are allowed as an alternative way of specifying more than one non-metric-specific instance filters. An individual instance filter can be one of the following: - *name* Full instance name. For example, **sda** for *disk.dev* instances or **eth0** for *network.interface* instances. - *PID* Process ID for *proc* instances. - *command* Base name of a process for *proc* instances. For example, **pmcd** would match all [**pmcd**(1)](/pmcd/1.md) processes regardless of their path or PID. - *regex* Regular expression. For example, **.\*python.\*** would match all instances having the string **python** as part of their instance name, meaning that this would match all Python processes regardless of their path, PID, or version. As an example, the following would report the same instances: ``` $ pmrep -i '. minute' kernel.all.load $ pmrep -i '1 minute','5 minute' kernel.all.load $ pmrep -i "'1 minute','5 minute'" kernel.all.load $ pmrep -i '1 minute' -i '5 minute' kernel.all.load $ pmrep kernel.all.load,,"'1 minute','5 minute'" $ pmrep kernel.all.load,,'1 minute|5 minute' ``` However, this would report only the 1-minute instance: ``` $ pmrep -i '1 minute','5 minute' kernel.all.load,,'1 minute' ``` And this would report all instances (due to per-metric regex): ``` $ pmrep -i '1 minute','5 minute' 'kernel.all.load,,.*' ``` - **-I**, **--ignore-incompat** Similar to unknown metrics described above for the **-5** option, a metric that **pmrep** is asked to report may be considered \`\`incompatible'' for a number of reasons: a metric type that is not supported by **pmrep** (e.g. PM\_TYPE\_AGGREGATE or PM\_TYPE\_EVENT), or a derived metric definition that contains semantic errors, or the metric is known in the PMNS but the metric's metadata is not available. By default, **pmrep** will report errors and exit if **any** requested metric is incompatible. The **-I** option changes the default behaviour and **pmrep** will silently ignore any metric that is incompatible, provided at least one compatible metric remains to be reported. This may be especially useful when requesting non-leaf nodes of the PMNS tree for reporting when the associated metrics have different metadata. - **--include-texts** When writing a PCP archive, include PCP metric help texts in the created archive. - **-j**, **--live-filter** Perform instance live filtering. This allows capturing all named instances even if processes are restarted at some point (unlike without live filtering). Performing live filtering over a huge number of instances will add some internal overhead so a bit of user caution is advised. See also **-1** and **-n**. - **-J** *rank*, **--rank**=*rank* Limit results to highest/lowest *rank*ed instances of set-valued metrics. A positive integer will include highest valued instances in reporting. A negative integer will include lowest valued instances in reporting. A value of zero performs no ranking. Ranking does not imply sorting, see **-6**. See also **-2** and **-8**. - **-k**, **--extended-csv** Write extended CSV output, similar to [**sadf**(1)](/sadf/1.md). See also **--csv-unit-info**. - **-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)](/pmSpecLocalPMDA/3.md). More than one **-K** option may be used. - **-l** *delimiter*, **--delimiter**=*delimiter* Specify the *delimiter* that separates each column of *csv* or *stdout* output. The default for *stdout* is two spaces (\`\` '') and comma (\`\`,'') for *csv*. When using a non-whitespace delimiter, all instances of the delimiter in string values will be replaced by the underscore (\`\`\_'') character. Note that many default metricsets specify a delimiter (that may not be a comma) so it might be necessary to use this option with metricsets to explicitly set the delimiter as comma for CSV output, i.e. . **--delimiter=,** - **-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. - **-n**, **--invert-filter** Perform ranking before live filtering. By default instance live filtering (when requested, see **-j**) happens before instance ranking (when requested, see **-J**). With this option the logic is inverted and ranking happens before live filtering. - **-N** *predicate*, **--predicate**=*predicate* Specify a comma-separated list of *predicate* filter reference metrics. By default ranking (see **-J**) happens for each metric individually. With predicates, ranking is done only for the specified predicate metrics. When reporting, rest of the metrics sharing the same *instance domain* (see [**PCPIntro**(1)](/PCPIntro/1.md)) as the predicate will include only the highest/lowest ranking instances of the corresponding predicate. Ranking does not imply sorting, see **-6**. So for example, using **proc.memory.rss** (resident memory size of process) as the *predicate* metric together with **proc.io.total\_bytes** and **mem.util.used** as metrics to be reported, only the processes using most/least (as per **-J**) memory will be included when reporting total bytes written by processes. Since **mem.util.used** is a single-valued metric (thus not sharing the same instance domain as the process related metrics), it will be reported as usual. - **--no-inst-info** Omit instance information from headers. Not applicable with separate header (see **-g**). - **-o** *output*, **--output**=*output* Use *output* target for reporting. The default target is *stdout*. The available output target alternatives are: - *archive* Record metrics into a PCP archive which can later be replayed with PCP tools, including **pmrep** itself. See [**LOGARCHIVE**(5)](/LOGARCHIVE/5.md) and [**PCPIntro**(1)](/PCPIntro/1.md) for details about PCP archive files. Requires **-F**. - *csv* Print metrics in CSV format (subject to formatting options). - *stdout* Print metrics to stdout (format subject to formatting options). - **-O** *origin*, **--origin**=*origin* When reporting archived metrics, start reporting at *origin* within the time window (see **-S** and **-T**). Refer to [**PCPIntro**(1)](/PCPIntro/1.md) for a complete description of the syntax for *origin*. - **-p**, **--timestamps** Print timestamps. By default no timestamps are printed. - **-P** *precision*, **--precision**=*precision* Use *precision* for numeric non-integer output values. If the value is too wide for its column width, *precision* is reduced one by one until the value fits, or not printed at all if it does not. 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)](/pmParseUnitsStr/3.md). - **-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. When writing archives, raw values are always used. 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, **pmrep** 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)](/PCPIntro/1.md) 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)](/PCPIntro/1.md), and in the simplest form may be an unsigned integer (the implied units in this case are seconds). See also the **-T** and **-u** options. - **-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)](/PCPIntro/1.md) for a complete description of the syntax for *endtime*. When used to define the runtime before **pmrep** 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 **pmrep** will run. - **-u**, **--no-interpol** When reporting archived metrics, by default values are reported according to the selected sample interval (**-t** option), not according to the actual record interval in an archive. To this effect PCP interpolates the values to be reported based on the records in the archive. With the **-u** option uninterpolated reporting is enabled, every recorded value for the selected metrics is reported and the requested sample interval (**-t**) is ignored. So for example, if a PCP archive contains recorded values for every 10 seconds and the requested sample interval is 1 hour, by default **pmrep** will use an interpolation scheme to compute the values of the requested metrics from the values recorded in the proximity of these requested metrics and values for every 1 hour are reported. With **-u** every record every 10 seconds are reported as such (the reported values are still subject to rate conversion, use **-r** or **-R** to disable). - **-U**, **--no-unit-info** Omit unit information from *stdout* headers. - **-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. - **-w** *width*, **--width**=*width* Set the *stdout* output column *width*. Strings will be truncated to this width. The default *width* is the shortest that can fit the metric text label, the forced minimum is 3. This option will *not* override possible per-metric specifications. - **-W** *width*, **--width-force**=*width* Like **-w** but this option *will* override per-metric specifications. - **-x**, **--extended-header** Print extended header. - **-X** *label*, **--colxrow**=*label* Swap columns and rows in *stdout* output, reporting one instance per line, using *label* as the text label for the instance column. Use an empty string ("") to enable swapping without a specific column label. This change in output allows using [**grep**(1)](/grep/1.md) to filter results or to more closely mimic other tools. See also **-i** and **-6**. - **-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)](/pmParseUnitsStr/3.md). - **-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)](/environ/7.md). 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. ## EXAMPLES The following examples use the standard PCP facilities for collecting the metric values, no external utilities are needed.

The **$PCP\_CONF** variable may be used to specify an alternative configuration file, as described in [**pcp.conf**(5)](/pcp.conf/5.md). For environment variables affecting PCP tools, see [**pmGetOptions**(3)](/pmGetOptions/3.md). Of particular note, **PCP\_DISCRETE\_ONCE** can be set to ensure that discrete metric values are reported only once, unless they change at some point. ## DEBUGGING OPTIONS The **-D** or **--debug** option enables the output of additional diagnostics on *stderr* to help triage problems, although the information is sometimes cryptic and primarily intended to provide guidance for developers rather than for end-users. *debug* is a comma separated list of debugging options; use [**pmdbg**(1)](/pmdbg/1.md) with the **-l** option to obtain a list of the available debugging options and their meaning. Debugging options specific to **pmrep** are as follows: | | | | --- | --- | | Option | Description | | appl1 | dump keywords for configurations and specifications | | derive | dump details as each derived metric is parsed | ## SEE ALSO [**PCPIntro**(1)](/PCPIntro/1.md), [**mkaf**(1)](/mkaf/1.md), [**pcp**(1)](/pcp/1.md), [**pcp2elasticsearch**(1)](/pcp2elasticsearch/1.md), [**pcp2graphite**(1)](/pcp2graphite/1.md), [**pcp2influxdb**(1)](/pcp2influxdb/1.md), [**pcp2json**(1)](/pcp2json/1.md), [**pcp2spark**(1)](/pcp2spark/1.md), [**pcp2xlsx**(1)](/pcp2xlsx/1.md), [**pcp2xml**(1)](/pcp2xml/1.md), [**pcp2zabbix**(1)](/pcp2zabbix/1.md), [**pcp-atop**(1)](/pcp-atop/1.md), [**pmcd**(1)](/pmcd/1.md), [**pmchart**(1)](/pmchart/1.md), [**pmdiff**(1)](/pmdiff/1.md), [**pmdumptext**(1)](/pmdumptext/1.md), [**pminfo**(1)](/pminfo/1.md), [**pmiostat**(1)](/pmiostat/1.md), [**pmlogdump**(1)](/pmlogdump/1.md), [**pmlogextract**(1)](/pmlogextract/1.md), [**pmlogsummary**(1)](/pmlogsummary/1.md), [**pmprobe**(1)](/pmprobe/1.md), [**pmstat**(1)](/pmstat/1.md), [**pmval**(1)](/pmval/1.md), [**sadf**(1)](/sadf/1.md), [**sar**(1)](/sar/1.md), [**PMAPI**(3)](/PMAPI/3.md), [**pmGetOptions**(3)](/pmGetOptions/3.md), [**pmLoadDerivedConfig**(3)](/pmLoadDerivedConfig/3.md), [**pmParseUnitsStr**(3)](/pmParseUnitsStr/3.md), [**pmRegisterDerived**(3)](/pmRegisterDerived/3.md), [**pmSpecLocalPMDA**(3)](/pmSpecLocalPMDA/3.md), [**strftime**(3)](/strftime/3.md), [**LOGARCHIVE**(5)](/LOGARCHIVE/5.md), [**PMNS**(5)](/PMNS/5.md), [**pcp.conf**(5)](/pcp.conf/5.md), [**pmrep.conf**(5)](/pmrep.conf/5.md), [**environ**(7)](/environ/7.md) and [**vmstat**(8)](/vmstat/8.md).
