Schema dei contatori delle prestazioni
I provider di dati sulle prestazioni V2 sono supportati in Windows Vista o versioni successive. Usano un oggetto . File MAN (manifesto di strumentazione XML) per definire il provider, i contatori e i contatori.
Nota
I manifesti di strumentazione possono contenere informazioni sui provider di Traccia eventi per Windows (ETW) e sui provider di contatori delle prestazioni. Per informazioni dettagliate sui manifesti di strumentazione, vedere Schema EventManifest e Scrittura di un manifesto di strumentazione.
Questa sezione descrive gli elementi e i tipi seguenti usati nella counters sezione di un manifesto di strumentazione:
- Elementi contatori delle prestazioni
- Contatori delle prestazioni tipi semplici
- Contatori delle prestazioni tipi complessi
Non usare le localization sezioni o stringTable del manifesto di strumentazione per le stringhe di dati delle prestazioni. Specificare invece le stringhe come valori dell'attributo impostato.
Dopo aver creato il manifesto, usare lo strumento CTRPP per convalidare il manifesto e generare file di codice () e risorsa (.h.rc) da usare nella compilazione del provider.
Quando si installa l'applicazione, eseguire lo strumentoLodCtr.exe con il /M: parametro per installare i contatori delle prestazioni. Lo strumento LodCtr.exe registra le informazioni necessarie nel Registro di sistema in HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\_V2Providers\{ProviderGuid}, incluso il percorso completo del file binario contenente le risorse stringa per il provider , come specificato nell'attributo applicationIdentity del manifesto. È necessario disporre dei privilegi di amministratore per eseguire LodCtr.exe. Comando di installazione di esempio:
LodCtr.exe /M:"manifesto" ["ApplicationIdentityDirectory"]
Se è necessario aggiornare un contatore, assicurarsi di disinstallare il vecchio contatore usando lo strumentoUnlodCtr.exe con i /G: parametri o /P: . Dopo la disinstallazione del contatore precedente, è possibile installare il contatore aggiornato.
SCHEMA
Di seguito è riportato lo schema dei contatori delle prestazioni che è possibile usare per convalidare la counters sezione del manifesto. Questo schema è disponibile in Windows SDK come counterman.xsd. Per informazioni dettagliate sullo schema usato per convalidare la sezione di strumentazione del manifesto, vedere Schema EventManifest.
