A budget is a plan that describes what you expect to spend on Cloud
projects, plus the rules to execute as spend is tracked against that plan,
(for example, send an alert when 90% of the target spend is met).
The budget time period is configurable, with options such as month (default),
quarter, year, or custom time period.
Describes a budget amount targeted to the last
[Filter.calendar_period][google.cloud.billing.budgets.v1beta1.Filter.calendar_period]
spend. At this time, the amount is automatically 100% of the last calendar
period's spend; that is, there are no other options yet.
Future configuration options will be described here (for example, configuring
a percentage of last period's spend).
LastPeriodAmount cannot be set for a budget configured with
a
[Filter.custom_period][google.cloud.billing.budgets.v1beta1.Filter.custom_period].
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.
A CalendarPeriod represents the abstract concept of a time period that
has a canonical start. Grammatically, "the start of the current
CalendarPeriod". All calendar times begin at 12 AM US and Canadian
Pacific Time (UTC-8).
Specifies how credits are applied when determining the spend for
threshold calculations. Budgets track the total cost minus any applicable
selected credits.
See the documentation for a list of credit
types.
