- ppppmmmmvvvvaaaallll prints current or archived values for the nominated performance
- metric. The metric of interest is named in the _m_e_t_r_i_c_n_a_m_e argument,
- subject to instance qualification with the ----iiii flag as described below.
-
- Unless directed to another host by the ----hhhh option, or to an archive by the
- ----aaaa option, ppppmmmmvvvvaaaallll will contact the Performance Metrics Collector Daemon
- (PMCD) on the local host to obtain the required information.
-
- When processing an archive, ppppmmmmvvvvaaaallll may relinquish its own timing control,
- and operate as a ``slave'' of a ppppmmmmttttiiiimmmmeeee(1) process that uses a GUI dialog
- to provide timing control. In this case, either the ----gggg option should be
- used to start ppppmmmmvvvvaaaallll as the sole slave of a new ppppmmmmttttiiiimmmmeeee(1) instances, or ----pppp
- should be used to attach ppppmmmmvvvvaaaallll to an existing ppppmmmmttttiiiimmmmeeee(1) instance via the
- IPC channel identified by the _p_o_r_t argument.
-
- The ----SSSS, ----TTTT, ----OOOO and ----AAAA options may be used to define a time window to
- restrict the samples retrieved, set an initial origin within the time
- window, or specify a ``natural'' alignment of the sample times; refer to
- PPPPCCCCPPPPIIIInnnnttttrrrroooo(1) for a complete description of these options.
-
- Options which control the source, timing and layout of the information
- reported by ppppmmmmvvvvaaaallll are as follows:
-
- ----aaaa Performance metric values are retrieved from the Performance Co-
- Pilot (PCP) archive log file identified by the base name _a_r_c_h_i_v_e.
-
- ----dddd When replaying from an archive, this option requests that the
- prevailing real-time delay be applied between samples (see ----tttt) to
- effect a pause, rather than the default behaviour of replaying at
- full speed.
-
- ----gggg Start ppppmmmmvvvvaaaallll as the slave of a new ppppmmmmttttiiiimmmmeeee(1) process for replay of
- archived performance data using the ppppmmmmttttiiiimmmmeeee(1) graphical user
- interface. NNNNooootttteeee: This option is supported on Irix only.
-
- ----hhhh Current performance metric values are retrieved from the nominated
- _h_o_s_t machine.
-
- ----iiii _i_n_s_t_a_n_c_e_s is a list of one or more instance names for the nominated
- performance metric - just these instances will be retrieved and
- reported (the default is to report all instances). The list must be
- a single argument, with elements of the list separated by commas
- and/or white space.

-
-
-
- ----nnnn Normally ppppmmmmvvvvaaaallll operates on the default Performance Metrics Name
- Space (PMNS), however if the ----nnnn option is specified an alternative
- namespace is loaded from the file _p_m_n_s_f_i_l_e.
-
- ----pppp Attach ppppmmmmvvvvaaaallll to an existing ppppmmmmttttiiiimmmmeeee(1) time control process instance
- via the IPC channel identified by the _p_o_r_t argument. This option is
- normally only used by other tools, e.g. ppppmmmmvvvviiiieeeewwww(1), when they launch
- ppppmmmmvvvvaaaallll with synchronized time control. NNNNooootttteeee: This option is
- suppored on Irix only.
-
- ----rrrr Print raw values for cumulative counter metrics. Normally
- cumulative counter metrics are converted to rates. For example,
- disk transfers are reported as number of disk transfers per second
- during the preceding sample interval, rather than the raw value of
- number of disk transfers since the machine was booted. If you
- specify this option, the raw metric values are printed.
-
- ----ssss The argument _s_a_m_p_l_e_s defines the number of samples to be retrieved
- and reported. If _s_a_m_p_l_e_s is 0 or ----ssss is not specified, ppppmmmmvvvvaaaallll will
- sample and report continuously (in real time mode) or until the end
- of the PCP archive (in archive mode).
-
- ----tttt The default update _i_n_t_e_r_v_a_l may be set to something other than the
- default 1 second. The _i_n_t_e_r_v_a_l argument follows the syntax
- described in PPPPCCCCPPPPIIIInnnnttttrrrroooo(1), and in the simplest form may be an
- unsigned integer (the implied units in this case are seconds).
-
- ----wwww Set the width of each column of output to be _w_i_d_t_h columns. If not
- specified columns are wide enough to accommodate the largest value
- of the type being printed.
-
- ----ZZZZ By default, ppppmmmmvvvvaaaallll reports the time of day according to the local
- timezone on the system where ppppmmmmvvvvaaaallll is run. The ----ZZZZ option changes
- the timezone to _t_i_m_e_z_o_n_e in the format of the environment variable
- TTTTZZZZ as described in eeeennnnvvvviiiirrrroooonnnn(5).
-
- ----zzzz Change the reporting timezone to the local timezone at the host that
- is the source of the performance metrics, as identified via either
- the ----hhhh or ----aaaa options.
-
- The following symbols may occasionally appear, in place of a metric
- value, in ppppmmmmvvvvaaaallll output: A question mark symbol (?) indicates that a
- value is no longer available for that metric instance. An exclamation
- mark (!) indicates that a 64-bit counter wrapped during the sample.
-
- The output from ppppmmmmvvvvaaaallll is directed to standard output.

- Environment variables with the prefix PPPPCCCCPPPP____ are used to parameterize the
- file and directory names used by PCP. On each installation, the file
- /_e_t_c/_p_c_p._c_o_n_f contains the local values for these variables. The
- $$$$PPPPCCCCPPPP____CCCCOOOONNNNFFFF variable may be used to specify an alternative configuration

- ppppmmmmvvvvaaaallll attempts to display non-integer numeric values in a way that does
- not distort the inherent precision (rarely more than 4 significant
- digits), and tries to maintain a tabular format in the output. These
- goals are sometimes in conflict.
-
- The following table describes the formats used for different ranges of
- numeric values for any metric that is of type PPPPMMMM____TTTTYYYYPPPPEEEE____FFFFLLLLOOOOAAAATTTT or
- PPPPMMMM____TTTTYYYYPPPPEEEE____DDDDOOOOUUUUBBBBLLLLEEEE, or any metric that has the semantics of a counter (for
- which ppppmmmmvvvvaaaallll reports the rate converted value):
