Schéma des compteurs de performance

Les fournisseurs de données de performances V2 sont pris en charge sur Windows Vista ou version ultérieure. Ils utilisent un . Fichier MAN (XML instrumentation manifest) pour définir le fournisseur, les compteurs et les compteurs.

Notes

Les manifestes d’instrumentation peuvent contenir des informations sur les fournisseurs de suivi d’événements pour Windows (ETW) et les fournisseurs de compteurs de performances. Pour plus d’informations sur les manifestes d’instrumentation, consultez Schéma EventManifest et Écriture d’un manifeste d’instrumentation).

Cette section décrit les éléments et types suivants que vous utilisez dans la counters section d’un manifeste d’instrumentation :

• Éléments des compteurs de performances
• Types simples des compteurs de performances
• Types complexes des compteurs de performances

N’utilisez pas les localization sections ou stringTable du manifeste d’instrumentation pour les chaînes de données de performance. Au lieu de cela, spécifiez les chaînes en tant que valeurs de l’attribut que vous définissez.

Après avoir créé le manifeste, utilisez l’outil CTRPP pour valider le manifeste et générer des fichiers de code (.h) et de ressources (.rc) à utiliser dans la création de votre fournisseur.

Lorsque vous installez votre application, exécutez l’outilLodCtr.exe avec le /M: paramètre pour installer vos compteurs de performances. L’outil LodCtr.exe enregistre les informations nécessaires dans le Registre sous HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\_V2Providers\{ProviderGuid}, y compris le chemin d’accès complet au fichier binaire contenant les ressources de chaîne pour votre fournisseur (comme spécifié dans l’attribut applicationIdentity du manifeste). Vous devez disposer de privilèges d’administrateur pour exécuter LodCtr.exe. Exemple de commande d’installation :

LodCtr.exe /M:"manifest » ["ApplicationIdentityDirectory"]

Si vous devez mettre à jour un compteur, veillez à désinstaller l’ancien compteur à l’aide de l’outilUnlodCtr.exe avec les /G: paramètres ou /P: . Une fois l’ancien compteur désinstallé, vous pouvez installer le compteur mis à jour.

schéma

Voici le schéma des compteurs de performances que vous pouvez utiliser pour valider la counters section de votre manifeste. Ce schéma se trouve dans le Kit de développement logiciel (SDK) Windows en tant que counterman.xsd. Pour plus d’informations sur le schéma que vous utilisez pour valider la section instrumentation du manifeste, consultez Schéma EventManifest.
