  @param appId ID of the application. This is Application ID from the API Access settings blade in the Azure portal.
  @param eventType The type of events to query; either a standard event type (`traces`, `customEvents`, `pageViews`, `requests`, `dependencies`, `exceptions`, `availabilityResults`) or `$all` to query across all event types. Possible values include: '$all', 'traces', 'customEvents', 'pageViews', 'browserTimings', 'requests', 'dependencies', 'exceptions', 'availabilityResults', 'performanceCounters', 'customMetrics'
  @param eventId ID of event.
  @throws IllegalArgumentException thrown if parameters fail the validation
