Logs

The loadbalancing_logs dataset collects logs of the requests sent to and handled by GCP Load Balancers.

An example event for loadbalancing looks as following:

ECS Field Reference

Please refer to the following document for detailed information on ECS fields.

Exported fields

Field	Description	Type
@timestamp	Event timestamp.	date
cloud.image.id	Image ID for the cloud instance.	keyword
data_stream.dataset	Data stream dataset.	constant_keyword
data_stream.namespace	Data stream namespace.	constant_keyword
data_stream.type	Data stream type.	constant_keyword
event.dataset	Event dataset	constant_keyword
event.module	Event module	constant_keyword
gcp.load_balancer.backend_service_name	The backend service to which the load balancer is sending traffic	keyword
gcp.load_balancer.cache_hit	Whether or not an entity was served from cache (with or without validation).	boolean
gcp.load_balancer.cache_id	Indicates the location and cache instance that the cache response was served from. For example, a cache response served from a cache in Amsterdam would have a cacheId value of AMS-85e2bd4b, where AMS is the IATA code, and 85e2bd4b is an opaque identifier of the cache instance (because some Cloud CDN locations have multiple discrete caches).	keyword
gcp.load_balancer.cache_lookup	Whether or not a cache lookup was attempted.	boolean
gcp.load_balancer.forwarding_rule_name	The name of the forwarding rule	keyword
gcp.load_balancer.status_details	Explains why the load balancer returned the HTTP status that it did. See https://cloud.google.com/cdn/docs/cdn-logging-monitoring#statusdetail\_http\_success\_messages for specific messages.	keyword
gcp.load_balancer.target_proxy_name	The target proxy name	keyword
gcp.load_balancer.url_map_name	The URL map name	keyword
host.containerized	If the host is a container.	boolean
host.os.build	OS build information.	keyword
host.os.codename	OS codename, if any.	keyword
input.type	Input type	keyword
log.offset	Log offset	long
