Displays of Measurement Data
For each entity type you specify for measurement, information is gathered by a set of
predefined counters. For example, if you specify a CPU entity type, predefined
counters collect information such as CPU busy time, interrupt busy time, number of
pages swapped, and so on.
You can measure all resources of a specific type, or you can identify specific resources
to be measured. For example, you can gather data on all CPUs of a system or on
selected CPUs, such as CPU 0, CPU 4, and CPU 12.
You can specify multiple entity types in the same measurement configuration. For
example, you can measure all disks and processes on a system, plus several CPUs,
files, and terminals in the same configuration.
You can define your own counters in user applications to set up new performance
indicators for your applications, such as number of user transactions, the length of a
request queue, or the amount of time spent performing certain functions.
You can specify both predefined and user-defined counters for measurement in the
same configuration.
Displays of Measurement Data
The standard data display is a listing of counter values by entity type. You can select
the entity type and manipulate the content and format of these displays. For example,
you can select a report that shows only totals for each counter of an entity, or you can
display both the totals and the individual counter values for an entity on the same
report. You can also display actual counter values or select a report that converts
actual counts into averages, percentages, and counts per second.
You can also display data in a data file in plot and bar-chart formats. These displays
help when you compare counter values for the same or different entities. You can
quickly change the type and scale of the graph and the time window of the data.
For further analysis, you can write Measure counter records to structured files, then
customize reports of measurement data using the Enform query product or the
SQL/MP command interpreter and report writer.
Customized Performance Tools
All Measure control, status, and data access functions are available through a callable
interface. The Measure command interpreter, MEASCOM, uses this interface to control
the Measure subsystem. You can also use the callable interface to implement custom
performance evaluation tools based on Measure data.
