That means that they are aggregated for all web apps running in that version of ASP. Then aspnet_calls The state service counters are a little bit different. During framework setup this tool is actually called as a custom action by the installation framework. %windir%\System32\inetsrv), which does a job similar to that of aspnet_() with “ASP. NET_64” driver and remove the associated registry key.The library uses an IO completion thread from the CLR, which wakes up every time some client wants to get performance counter data.
The higher version registered on the machine “owns” the generic objects, while all versions “owns” their respective versioned objects. NET application running in a lower version, then the generic counters will not report numbers for that application. Also, under a 64 bit Os, the counters are not registered if you run the 32 bit version (wow64 process) of aspnet_() with that version’s aspnet_perf2
This allows side-by-side versions with different performance counters implementation. They are only registered together with the service, so once this is registered, the performance counters are not unreg/reg again in subsequent calls to aspnet_
The performance counters names are stored at HKLM\SOFTWARE\Microsoft\Windows NT\Current Version\Perflib\nnn, where nnn is the language id. NET Performance counters has generic categories (e.g. The logs are stored in the %TEMP% folder and are named something like ASPNETSetup_00
You need to use the versioned categories in that case. For instance, if both 2.0 and 4.0 are registered, then, calling aspnet_-u from the 4.0, would actually associate the 2.0 version with the generic counters.
These files can be examined, along with the event log when looking for clues of what went wrong. NET performance counters mechanism uses a client/server approach. During runtime, whenever a web application is run and the worker process starts, it loads (or webengine4in . This library, among other many things, will initialize the performance counters local storage in the process.
In this case, the server is the worker process; say w3wp.exe, while the clients are other processes that consume performance counter data using Win32 API, such as PDH, registry functions (e.g. It will also create a named pipe to which clients will be able to connect and read the counters data from.
Older versions had the export methods directly on the aspnet_ This library resides in the System32 directory (e.g. It replaced aspnet_in the registration, but it’s actually a shim, which redirects all calls to aspnet_ The problem with the previous registration design was that a full path was required in the “Library” value in both the versioned and the generic keys. First, you needed separated registry keys for 64 bit and 32 bit.
NET_2.0.50727) and the aspnet_state service performance counters.
The data is stored in a global area, and it will be returned to the clients through the Collect export.
