GCP Cloud Storage Metrics¶

This page lists the Cloud Storage metrics collected by the GCP app.

The table omits the metric type prefixes. For example, the full name of the request_count metric, of type api, is storage.googleapis.com/api/request_count.

API¶

Metric type prefix: storage.googleapis.com/api/

Metric	Description
`request_count`	Delta count of API calls, grouped by the API method name and response code.

AUTHN¶

Metric type prefix: storage.googleapis.com/authn/

Metric	Description
`authentication_count`	Count of HMAC/RSA signed requests grouped by authentication method and access id.

AUTHZ¶

Metric type prefix: storage.googleapis.com/authz/

Metric	Description
`acl_based_object_access_count`	Delta count of requests that result in an object being granted access solely due to object ACLs.
`acl_operations_count`	Usage of ACL operations broken down by type.
`object_specific_acl_mutation_count`	Delta count of changes made to object-specific ACLs.

Network¶

Metric type prefix: storage.googleapis.com/network/

Metric	Description
`received_bytes_count`	Delta count of bytes received over the network, grouped by the API method name and response code.
`sent_bytes_count`	Delta count of bytes sent over the network, grouped by the API method name and response code.

Replication¶

Metric type prefix: storage.googleapis.com/replication/

Metric	Description
`missing_rpo_minutes_last_30d`	Total number of minutes where the Recovery Point Objective (RPO) was missed, as measured over the most recent 30 days. The metric is delayed by storage.googleapis.com/replication/time_since_metrics_updated.
`object_replications_last_30d`	Total number of object replications, as measured over the most recent 30 days. The metric can be broken down by whether each object replication was meeting or missing Recovery Point Objective (RPO). The metric is delayed by storage.googleapis.com/replication/time_since_metrics_updated.
`time_since_metrics_updated`	Seconds since the last time when storage.googleapis.com/replication/* metrics were calculated.

Storage¶

Metric type prefix: storage.googleapis.com/storage/

Metric	Description
`object_count`	Total number of objects per bucket, grouped by storage class. This value is measured once per day, and there might be a delay after measuring before the value becomes available in Cloud Monitoring. Once available, the value is repeated at each sampling interval throughout the day. Buckets with no objects in them are not tracked by this metric. For this metric, the sampling period is a reporting period, not a measurement period.
`total_byte_seconds`	Total daily storage in byte*seconds used by the bucket, grouped by storage class. This value is measured once per day, and there might be a delay after measuring before the value becomes available in Cloud Monitoring. Once available, the value is repeated at each sampling interval throughout the day. Buckets with no objects in them are not tracked by this metric. For this metric, the sampling period is a reporting period, not a measurement period.
`total_bytes`	Total size of all objects in the bucket, grouped by storage class. This value is measured once per day, and there might be a delay after measuring before the value becomes available in Cloud Monitoring. Once available, the value is repeated at each sampling interval throughout the day. Buckets with no objects in them are not tracked by this metric. For this metric, the sampling period is a reporting period, not a measurement period.
