Esempi di modelli di Resource Manager per le regole di avviso delle metriche in Monitoraggio di Azure

  • Articolo

Questo articolo fornisce esempi dell'uso di modelli di Azure Resource Manager per configurare le regole di avviso delle metriche in Monitoraggio di Azure. Ogni esempio include un file modello e un file di parametri con valori di esempio da fornire al modello.

Nota

Per un elenco di esempi disponibili e indicazioni sulla distribuzione nella sottoscrizione di Azure, vedere Esempi di Azure Resource Manager per Monitoraggio di Azure.

Per un elenco delle risorse che è possibile usare con le regole di avviso delle metriche, vedere Risorse supportate per gli avvisi delle metriche in Monitoraggio di Azure. Per una spiegazione dello schema e delle proprietà di una regola di avviso, vedere Avvisi delle metriche: creazione o aggiornamento.

Nota

Il modello di risorsa per la creazione di avvisi delle metriche per il tipo di risorsa: Area di lavoro Log Analytics di Azure (ad esempio Microsoft.OperationalInsights/workspaces), richiede passaggi aggiuntivi. Per informazioni dettagliate, vedere Avviso delle metriche per i log: modello di risorsa.

Più criteri, soglia statica

Gli avvisi delle metriche supportano l'invio di avvisi per metriche multidimensionali e fino a 5 criteri per ogni regola di avviso. Nell'esempio seguente viene creata una regola di avviso delle metriche metrica per le metriche dimensionali e vengono specificati più criteri.

I vincoli seguenti si applicano quando si usano le dimensioni in una regola di avviso che contiene più criteri:

  • È possibile selezionare un solo valore per dimensione all'interno di ogni criterio.

  • Non è possibile utilizzare "*" come valore della dimensione.

  • Quando le metriche configurate in criteri diversi supportano la stessa dimensione, è necessario impostare esplicitamente un valore di dimensione, allo stesso modo per tutte le metriche nei criteri pertinenti.

    • Nelle esempio seguente, poiché sia le metriche Transactions che SuccessE2ELatency hanno una dimensione ApiName e criterion1 specifica il valore "GetBlob" per la dimensione ApiName, anche criterion2 deve impostare un valore "GetBlob" per la dimensione ApiName.

Più dimensioni, soglia statica

Una singola regola di avviso può monitorare più serie temporali di metriche alla volta, riducendo così il numero di regole di avviso da gestire. L'esempio seguente crea una regola di avviso statica per metriche dimensionali.

In questo esempio la regola di avviso monitora le combinazioni di valori delle dimensioni ResponseType e ApiName per la metrica Transactions:

  1. ResponsType : l'uso del carattere jolly "*" indica che per ogni valore della dimensione ResponseType , inclusi i valori futuri, viene monitorata singolarmente una serie temporale diversa.
  2. ApiName: viene monitorata una serie temporale diversa solo per i valori delle dimensioni GetBlob e PutBlob.

Ad esempio, alcune possibili serie temporali monitorate da questa regola di avviso sono:

  • Metrica = Transactions, ResponseType = Success, ApiName = GetBlob
  • Metrica = Transactions, ResponseType = Success, ApiName = PutBlob
  • Metrica = Transactions, ResponseType = Server Timeout, ApiName = GetBlob
  • Metrica = Transactions, ResponseType = Server Timeout, ApiName = PutBlob

    }
  }
}

Nota

L'uso di "All" come valore della dimensione equivale a selezionare "*" (tutti i valori correnti e futuri).

Più dimensioni, soglie dinamiche

Una regola di avviso con soglie dinamiche può creare soglie personalizzate per centinaia di serie temporali di metriche (anche di tipi diversi) alla volta, riducendo così il numero di regole di avviso da gestire. L'esempio seguente crea una regola di avviso con soglie dinamiche per metriche dimensionali.

In questo esempio la regola di avviso monitora le combinazioni di valori delle dimensioni ResponseType e ApiName per la metrica Transactions:

  1. ResponsType: per ogni valore della dimensione ResponseType, inclusi i valori futuri, viene monitorata singolarmente una serie temporale diversa.
  2. ApiName: viene monitorata una serie temporale diversa solo per i valori delle dimensioni GetBlob e PutBlob.

Ad esempio, alcune possibili serie temporali monitorate da questa regola di avviso sono:

  • Metrica = Transactions, ResponseType = Success, ApiName = GetBlob
  • Metrica = Transactions, ResponseType = Success, ApiName = PutBlob
  • Metrica = Transactions, ResponseType = Server Timeout, ApiName = GetBlob
  • Metrica = Transactions, ResponseType = Server Timeout, ApiName = PutBlob

Nota

Attualmente per le regole di avviso delle metriche che usano soglie dinamiche non sono supportati più criteri.

Metrica personalizzata, soglia statica

È possibile usare il modello seguente per creare una regola di avviso con soglia statica per una metrica personalizzata.

Per altre informazioni sulle metriche personalizzate in Monitoraggio di Azure, vedere Metriche personalizzate in Monitoraggio di Azure.

Quando si crea una regola di avviso per una metrica personalizzata, è necessario specificare sia il nome che lo spazio dei nomi della metrica. È anche necessario assicurarsi che la metrica sia già stata segnalata, perché non è possibile definire una regola di avviso per una metrica personalizzata che non esiste ancora.

Per trovare lo spazio dei nomi di una specifica metrica personalizzata, esplorare le metriche personalizzate tramite il portale di Azure

Più risorse

Monitoraggio di Azure supporta il monitoraggio di più risorse dello stesso tipo con una singola regola di avviso delle metriche, per le risorse esistenti nella stessa area di Azure. Questa funzionalità è attualmente supportata solo nel cloud pubblico di Azure e solo per macchine virtuali, database di SQL Server, pool elastici di SQL Server e dispositivi Azure Stack Edge. Inoltre, questa funzionalità è disponibile solo per le metriche della piattaforma e non è supportata per le metriche personalizzate.

Le regole di avviso con soglie dinamiche possono anche creare soglie personalizzate per centinaia di serie di metriche (persino di tipi diversi) alla volta, riducendo così il numero di regole di avviso da gestire.

Questa sezione descrive i modelli di Azure Resource Manager per tre scenari per il monitoraggio di più risorse con una singola regola.

  • Monitoraggio di tutte le macchine virtuali (in un'area di Azure) in uno o più gruppi di risorse.
  • Monitoraggio di tutte le macchine virtuali (in un'area di Azure) in una sottoscrizione.
  • Monitoraggio di un elenco di macchine virtuali (in un'area di Azure) in una sottoscrizione.

Nota

  • In una regola di avviso delle metriche che monitora più risorse è supportata una sola condizione.
  • Se si crea un avviso di metrica per una singola risorsa, il modello usa la ResourceId proprietà della risorsa di destinazione. Se si sta creando un avviso per le metriche per più risorse, il modello usa scope, TargetResourceTypee TargetResourceRegion per le risorse di destinazione.

Avviso con soglia statica su tutte le macchine virtuali in uno o più gruppi di risorse

Questo modello creerà una regola di avviso delle metriche con soglia statica che monitora il valore di Percentuale CPU per tutte le macchine virtuali (in un'area di Azure) in uno o più gruppi di risorse.

Test di disponibilità con avviso delle metriche

I test di disponibilità di Application Insights consentono di monitorare la disponibilità del sito Web o dell'applicazione da diverse località in tutto il mondo. Gli avvisi dei test di disponibilità segnalano quando i test di disponibilità non riescono da un determinato numero di località. Gli avvisi dei test di disponibilità sono dello stesso tipo di risorsa degli avvisi delle metriche (Microsoft.Insights/metricAlerts). L'esempio seguente crea un semplice test di disponibilità e l'avviso associato.

Nota

& è il riferimento all'entità HTML per &. I parametri URL sono ancora separati da un singolo carattere &, ma se si cita l'URL in HTML, è necessario codificarlo. Quindi, se nel valore del parametro pingURL è presente un carattere "&", è necessario eseguirne l'escape con "&"
