Описание (Description)

pmview is a generalized 3D performance metrics visualization tool
       for the Performance Co-Pilot (PCP(1)).

       pmview is the base utility behind performance metrics
       visualization tools such as dkvis(1), mpvis(1), osvis(1) and
       nfsvis(1), It is also used by a range of related tools that are
       specific to optional Performance Domain Agents (PMDA) and/or PCP
       add-on products.  pmview may also be used to construct customized
       3D performance displays.

       pmview displays performance metrics as colored blocks and
       cylinders arranged on monochrome base planes. Each object may
       represent a single performance metric, or a stack of several
       performance metrics.  Since the objects are modulated by the
       value of the metric they represent, only numerical metrics may be
       visualized.  Objects representing a single metric may be
       modulated in terms of height, color, or height and color.
       Objects in a stack may only be height modulated, but the stack
       can be normalized to the maximum height.  Labels may be added to
       the scene to help identify groups of metrics.

       A configuration file (as specified by the -c option, or read from
       standard input) is used to specify the position, color, maximum
       value and labels of metrics and metric instances in the scene.
       The maximum value acts as a normalization factor and is used to
       scale the object height and/or color in proportion to the metric
       values.  Metric values which exceed the associated maximum value
       are displayed as solid white objects.  If a metric is
       unavailable, the object will have minimum height and will be
       colored grey.

       Normally, the tool operates in ``live'' mode where performance
       metrics are fetched in real-time.  The user can view metrics from
       any host running pmcd(1).  pmview can also replay archives of
       performance metrics (see pmlogger(1)) and allow the user to
       interactively control the current replay time and rate using the
       VCR paradigm.  This is particularly useful for retrospective
       comparisons and for post-mortem analysis of performance problems
       where a remote system is not accessible or a performance analyst
       is not available on-site.

       All metrics in the Performance Metrics Name Space (PMNS) with
       numeric value semantics from any number of hosts or archives may
       be visualized.  pmview examines the semantics of the metrics and
       where sensible, converts metric values to a rate before scaling.
