Esquema de contadores de desempenho
Há suporte para provedores de dados de desempenho V2 no Windows Vista ou posterior. Eles usam um . Arquivo MAN (manifesto de instrumentação XML) para definir o provedor, os contadores e os contadores.
Observação
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 Esquema EventManifest e Gravando um manifesto de instrumentação).
Esta seção descreve os seguintes elementos e tipos que você usa na counters seção 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 localization seções 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 ferramentaLodCtr.exe com o /M: parâmetro para instalar os contadores de desempenho. A ferramenta LodCtr.exe registrará as informações necessárias no registro HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\_V2Providers\{ProviderGuid}em , incluindo o caminho completo para o binário que contém os recursos de cadeia de caracteres para o provedor (conforme especificado no applicationIdentity atributo do manifesto). Você deve ter privilégios de administrador para executar LodCtr.exe. Exemplo de comando de instalação:
LodCtr.exe /M:"manifest" ["ApplicationIdentityDirectory"]
Se você precisar atualizar um contador, desinstale o contador antigo usando a ferramentaUnlodCtr.exe com os /G: parâmetros 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 counters seção 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 Esquema EventManifest.
