Specifies the audit configuration for a service. The configuration determines which permission types are logged, and what identities, if any, are exempted from logging. An AuditConfig must have one or more AuditLogConfigs. If there are AuditConfigs for both allServices and a specific service, the union of the two AuditConfigs is used for that service: the log_types specified in each AuditConfig are enabled, and the exempted_members in each AuditLogConfig are exempted. Example Policy with multiple AuditConfigs: { "audit_configs": [ { "service": "allServices", "audit_log_configs": [ { "log_type": "DATA_READ", "exempted_members": "user:jose@example.com" }, { "log_type": "DATA_WRITE" }, { "log_type": "ADMIN_READ" } ] }, { "service": "sampleservice.googleapis.com", "audit_log_configs": [ { "log_type": "DATA_READ" }, { "log_type": "DATA_WRITE", "exempted_members": "user:aliya@example.com" } ] } ] } For sampleservice, this policy enables DATA_READ, DATA_WRITE and ADMIN_READ logging. It also exempts jose@example.com from DATA_READ logging, and aliya@example.com from DATA_WRITE logging.

A metadata key/value entry.
Builder for MetadataArgs.
Opaque filter criteria used by load balancers to restrict routing configuration to a limited set of load balancing proxies. Proxies and sidecars involved in load balancing would typically present metadata to the load balancers that need to match criteria specified here. If a match takes place, the relevant configuration is made available to those proxies. For each metadataFilter in this list, if its filterMatchCriteria is set to MATCH_ANY, at least one of the filterLabels must match the corresponding label provided in the metadata. If its filterMatchCriteria is set to MATCH_ALL, then all of its filterLabels must match with corresponding labels provided in the metadata. An example for using metadataFilters would be: if load balancing involves Envoys, they receive routing configuration when values in metadataFilters match values supplied in of their XDS requests to loadbalancers.
