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.
----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.
----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.

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):
