Create alerts via Bicep

Create alerts via Bicep

It is possible to automate alert deployment with bicep. This leverages the Microsoft.Insights/scheduledQueryRules@2018-04-16 and custom AI query. To store info for the alerts TelemetryCleint can be used in a following way:

// Trigger alert by logging a custom event in AppInsights
_telemetryClient.TrackEvent(
eventName: "APP.Entities.NotReceived",
properties: new Dictionary<string, string>()
{
  { "InternalId", attachment.Id.ToString() },
  { "Name", entity.Name },
  { "Number", entity.Number },
  { "DocumentType", entity.Document.Type },
});
