Name
PerformanceCounterCategory
Synopsis
This class allows you to create and manage categories of
performance counters. You can see the categories recognized by
your system when you use the Performance Administrative Tool.
When you attempt to add a counter, you’ll see the categories
listed in the Performance
object drop-list, such as Processor,
Memory, Thread, and Network Interface.
Use Create()
to add a new category.
The three-argument form lets you supply a category name, a
description of the category, and a collection of
CounterCreationData
objects. Each
CounterCreationData
object describes a
counter to create in the new category. Use the
four-argument form of Create()
to
create a new category with only a single counter.
Delete()
removes a counter category,
and Exists()
checks whether a given category
exists. If you want to check if a specific counter exists in a
category, call CounterExists()
. To check
for an instance in a category, use
InstanceExists()
.
GetCategories()
returns all the categories
recognized by the system.
The CategoryHelp
,
CategoryName
, and MachineName
properties provide access to the name, help text, and machine name
for a given category. You can use the non-static versions of
CounterExists()
and
InstanceExists()
to check if a specified counter
or instance exists in the inspected category.
GetCounters()
and
GetInstanceNames()
retrieve a list of the
counters and instances in a category.
