Monitorare i costi dei processi con le tabelle di sistema
Importante
Questa tabella di sistema è disponibile in anteprima pubblica. Per accedere alla tabella, è necessario abilitare lo schema nel catalogo system
. Per altre informazioni, vedere Abilitare gli schemi di tabella di sistema.
Questo articolo offre esempi di come usare le tabelle di sistema per monitorare il costo dei processi nell'account.
Queste query calcolano solo i costi per i processi eseguiti nel calcolo dei processi e nel calcolo serverless. I processi eseguiti in SQL Warehouse e le risorse di calcolo per tutti gli scopi non vengono fatturati come processi e pertanto vengono esclusi dall'attribuzione dei costi.
Nota
Queste query non restituiscono record dalle aree di lavoro esterne all'area cloud dell'area di lavoro corrente. Per monitorare i costi dei processi dalle aree di lavoro esterne all'area corrente, eseguire queste query in un'area di lavoro distribuita in tale area.
Dashboard di osservabilità dei costi
Per iniziare a monitorare i costi dei processi, scaricare il dashboard di osservabilità dei costi seguente da GitHub. Vedere Dashboard costi e osservabilità dell'integrità dei processi.
Dopo aver scaricato il file JSON, importare il dashboard nell'area di lavoro. Per istruzioni sull'importazione dei dashboard, vedere Importare un file del dashboard.
Processi con il cambiamento più elevato della spesa negli ultimi 7-14 giorni
Questa query identifica quali processi hanno registrato l'aumento più elevato della spesa per i costi di elenco nelle ultime 2 settimane.
