public sealed class ThresholdRule : IMessage<ThresholdRule>, IEquatable<ThresholdRule>, IDeepCloneable<ThresholdRule>, IBufferMessage, IMessage
Reference documentation and code samples for the Cloud Billing Budget v1 API class ThresholdRule.
ThresholdRule contains the definition of a threshold. Threshold rules define
the triggering events used to generate a budget notification email. When a
threshold is crossed (spend exceeds the specified percentages of the
budget), budget alert emails are sent to the email recipients you specify
in the
NotificationsRule.
Threshold rules also affect the fields included in the
JSON data
object
sent to a Pub/Sub topic.
Threshold rules are required if using email notifications.
Threshold rules are optional if only setting a
pubsubTopic NotificationsRule,
unless you want your JSON data object to include data about the thresholds
you set.
