Example

The example below illustrates how to create a web application and set up a diagnostics setting against it, whilst setting up three destinations for the diagnostics (storage, event hub and log analytics). Also notice the using of the Logging. namespace, which contains all documented Logging categories.

open Farmer
open Farmer.Builders
open Farmer.DiagnosticSettings

let data = storageAccount { name "isaacsuperdata" }
let hub = eventHub { name "isaacsuperhub" }
let logs = logAnalytics { name "isaacsuperlogs" }
let web = webApp { name "isaacdiagsuperweb"; app_insights_off }

let mydiagnosticSetting = diagnosticSettings {
    name "myDiagnosticSetting"
    metrics_source web

    add_destination data
    add_destination logs
    add_destination hub
    loganalytics_output_type Dedicated
    capture_metrics [ "AllMetrics" ]
    capture_logs [
        Logging.Web.Sites.AppServicePlatformLogs
        Logging.Web.Sites.AppServiceAntivirusScanAuditLogs
    ]
}

let deployment = arm {
    add_resources [ data; web; hub; logs; mydiagnosticSetting ]
}
