Описание (Description)
pmchart is a graphical utility that plots performance metrics
values available through the facilities of the Performance Co-
Pilot (PCP). Multiple charts can be displayed simultaneously,
either aligned on the unified time axis (X-axis), and through the
use of multiple interface Tabs.
Metric values can be sourced from one or more live hosts
(simultaneously). Alternatively, one or more sets of PCP
archives can be used as a source of historical data. See
PCPIntro(1) for an in-depth discussion of the capabilities of the
PCP framework, many of which are used by pmchart.
Many aspects of the behaviour of pmchart can be customised
through the interface. In particular, the use of "views" (refer
to the section describing VIEWS later in this document) allows
predefined sets of metrics and charting parameters like colors,
scaling, titles, legends, and so on to be stored for later use,
or use with different hosts and sets of archives. In addition,
the Preferences dialog allows customisations to the rest of the
pmchart user interface to be saved and restored between different
invocations of the tool. This allows the default background
color, highlight color, contents and location of the toolbar, and
many other aspects to be configured.
pmchart makes extensive use of the pmtime(1) utility for time
control, refer to the pmtime manual page for further details of
its operation.
