extends com.google.protobuf.GeneratedMessageV3.Builder<AlertPolicy.Condition.PrometheusQueryLanguageCondition.Builder>
implements AlertPolicy.Condition.PrometheusQueryLanguageConditionOrBuilder
     A condition type that allows alert policies to be defined using
 [Prometheus Query Language
 (PromQL)](https://prometheus.io/docs/prometheus/latest/querying/basics/).

 The PrometheusQueryLanguageCondition message contains information
 from a Prometheus alerting rule and its associated rule group.

 A Prometheus alerting rule is described
 [here](https://prometheus.io/docs/prometheus/latest/configuration/alerting_rules/).
 The semantics of a Prometheus alerting rule is described
 [here](https://prometheus.io/docs/prometheus/latest/configuration/recording_rules/#rule).

 A Prometheus rule group is described
 [here](https://prometheus.io/docs/prometheus/latest/configuration/recording_rules/).
 The semantics of a Prometheus rule group is described
 [here](https://prometheus.io/docs/prometheus/latest/configuration/recording_rules/#rule_group).

 Because Cloud Alerting has no representation of a Prometheus rule
 group resource, we must embed the information of the parent rule
 group inside each of the conditions that refer to it. We must also
 update the contents of all Prometheus alerts in case the information
 of their rule group changes.

 The PrometheusQueryLanguageCondition protocol buffer combines the
 information of the corresponding rule group and alerting rule.
 The structure of the PrometheusQueryLanguageCondition protocol buffer
 does NOT mimic the structure of the Prometheus rule group and alerting
 rule YAML declarations. The PrometheusQueryLanguageCondition protocol
 buffer may change in the future to support future rule group and/or
 alerting rule features. There are no new such features at the present
 time (2023-06-26).
