windows-server-2008 – Windows性能计数器中的(*)是什么

Perfmon可能是最容易查看计数器并查看系统可用内容的地方.

从documentation for typeperf：

?Counter path format 

The general format for counter paths is as follows: [Computer]object[parent/instance#index]counter] where:

The parent,instance,index,and counter components of the format may contain either a valid name or a wildcard character. The computer,parent,and index components are not necessary for all counters.

You determine the counter paths to use based on the counter itself. For example,the LogicalDisk object has an instance index,so you must provide the #index or a wildcard. Therefore,you could use the following format:

LogicalDisk(*/*#*)*

In comparison,the Process object does not require an instance index. Therefore,you could use the following format:

Process(*)ID Process

The following is a list of the possible formats: ? machineobject(parent/instance#index)counter 

? machineobject(parent/instance)counter 

? machineobject(instance#index)counter 

? machineobject(instance)counter 

? machineobjectcounter 

? object(parent/instance#index)counter 

? object(parent/instance)counter 

? object(instance#index)counter 

? object(instance)counter 

? objectcounter

编辑：哦,别忘了在Powershell中查看Get-Counter：

PS C:&; (Get-Counter -ListSet Memory).Paths

MemoryPage Faults/sec
MemoryAvailable Bytes
MemoryCommitted Bytes
MemoryCommit Limit
MemoryWrite Copies/sec
MemoryTransition Faults/sec
MemoryCache Faults/sec
MemoryDemand Zero Faults/sec
MemoryPages/sec
MemoryPages Input/sec
...

The second command gets the path names that include "cache".
PS C:&; (Get-Counter -ListSet Memory).Paths | Where {$_ -like "*Cache*"}

MemoryCache Faults/sec
MemoryCache Bytes
MemoryCache Bytes Peak
MemorySystem Cache Resident Bytes
MemoryStandby Cache Reserve Bytes
MemoryStandby Cache Normal Priority Bytes
MemoryStandby Cache Core Bytes
