Esquema de contadores de desempenho
Os provedores de dados de desempenho V2 têm suporte no Windows Vista ou posterior. Eles usam um . Arquivo MAN (manifesto de instrumentação XML) para definir o provedor, os contadores e os contadores.
Nota
Os manifestos de instrumentação podem conter informações sobre provedores ETW (Rastreamento de Eventos para Windows) e provedores de Contador de Desempenho. Para obter detalhes sobre manifestos de instrumentação, consulte de esquema EventManifest e escrever um manifesto de instrumentação).
Esta seção descreve os seguintes elementos e tipos que você usa na seção counters de um manifesto de instrumentação:
- Elementos de contadores de desempenho
- tipos simples de contadores de desempenho
- tipos complexos de contadores de desempenho
Não use as seções localization ou stringTable do manifesto de instrumentação para cadeias de caracteres de dados de desempenho. Em vez disso, especifique as cadeias de caracteres como valores do atributo que você está definindo.
Depois de criar o manifesto, use a ferramenta CTRPP para validar o manifesto e gerar arquivos de código (.h) e de recurso (.rc) a serem usados na criação do provedor.
Ao instalar seu aplicativo, execute a ferramenta LodCtr.exe com o parâmetro /M: para instalar seus contadores de desempenho. A ferramenta LodCtr.exe registrará as informações necessárias no registro em HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\_V2Providers\{ProviderGuid}, incluindo o caminho completo para o binário que contém os recursos de cadeia de caracteres para o provedor (conforme especificado no atributo applicationIdentity do manifesto). Você deve ter privilégios de administrador para executar LodCtr.exe. Comando de instalação de exemplo:
LodCtr.exe /M:"manifesto" ["ApplicationIdentityDirectory"]
Se você precisar atualizar um contraconjunto, desinstale o contador antigo usando a ferramenta UnlodCtr.exe com os parâmetros /G: ou /P:. Depois que o contador antigo for desinstalado, você poderá instalar o contador atualizado.
Esquema
Veja a seguir o esquema de contadores de desempenho que você pode usar para validar a seção counters do manifesto. Esse esquema é encontrado no SDK do Windows como counterman.xsd. Para obter detalhes sobre o esquema que você usa para validar a seção de instrumentação do manifesto, consulte de Esquema EventManifest.
