Object Storage Metrics

Object Storage can store an unlimited amount of unstructured data of any content type, including analytic data and rich content, like images and videos. The Object Storage service metrics help you measure the amount of storage you're using. You can also use these metrics to monitor the performance of requests in terms of latency and utilization as measured by counts of requests made per bucket.

To monitor resources, you must be granted the required type of access in a policy  written by an administrator, whether you're using the Console or the REST API with an SDK, CLI, or other tool. The policy must give you access to the monitoring services as well as the resources being monitored. If you try to perform an action and get a message that you don't have permission or are unauthorized, contact the administrator to determine the type of access you were granted and which compartment  you need to work in. For more information about user authorizations for monitoring, see IAM Policies (Monitoring).

The metrics listed in the following tables are automatically available for any buckets you create. You do not need to enable monitoring on the resource to get these metrics. However, you must have an object stored in a bucket to get any metrics. Buckets with no objects emit no metric data.

Each metric includes the following dimensions :

RESOURCEID

The OCID  of the bucket to which the metric applies.

RESOURCEDISPLAYNAME

The name of the bucket .

TIER

The storage tier (standard or archive) where the object  resides.

Default Metrics

The following default metric charts are available for each Object Storage bucket from the bucket details page. See To view default metric charts for a bucket.

Metric	Metric Display Name	Unit	Description/ Emit Frequency	Dimensions
ObjectCount	Number of Objects	count	The count of objects in the bucket, excluding any multipart upload parts that have not been discarded (aborted) or committed. Emit frequency: every hour	resourceID resourceDisplayName tier
StoredBytes	Bucket Size	bytes	The size of the bucket, excluding any multipart upload parts that have not been discarded (aborted) or committed. Emit frequency: every hour

Custom Query Metrics

The following custom query metric charts are available using Metrics Explorer. See Using the Console.

Metric	Metric Display Name	Unit	Description/ Emit Frequency	Dimensions
AllRequests	All Requests Count	count	The total number of all HTTP requests made in a bucket. Emit frequency: every 100 ms	resourceID resourceDisplayName
ClientErrors	Client-Side Error Count	count	The total number of 4xx errors for requests made in a bucket. Emit frequency: every 100 ms
EnabledOLM	Enabled Object Lifecycle Management	count	Indicates whether a bucket has any executable Object Lifecycle Management policies configured. EnabledOLM emits: 1 if policies are configured 0 if no policies are configured Emit frequency: every 3 hours
FirstByteLatency	First Byte Latency Time	time (ms)	The per-request time measured from the time Object Storage receives the complete request to when Object Storage returns the first byte of the response. Emit frequency: every 100 ms
PostRequests	PostObject Request Count	count	The total number of HTTP Post requests made in a bucket. Emit frequency: every 100 ms
PutRequests	PutObject Request Count	count	The total number of PutObject requests made in a bucket. Emit frequency: every 100 ms
TotalRequestLatency	Overall Latency Time	time (ms)	The per-request time from the first byte received by Object Storage to the last byte sent from Object Storage. Emit frequency: every 100 ms
UncommittedParts	Incomplete MultiPart Upload Size	bytes	The size of any multipart upload parts that have not been discarded (aborted) or committed. Emit frequency: every hour	resourceID resourceDisplayName tier
