 #### Cost and observability correlation
 
-Viewing costs in the context of observability data is important for understanding how infrastructure changes impact costs, identifying why costs change, and optimizing infrastructure for both costs and performance.

 Datadog updates resource identifying tags on cost data for top OCI products to simplify correlating observability and cost metrics. For example, to view cost and utilization for each Compute instance, you can make a table with `oci.cost.amortized`, `oci.computeagent.cpu_utilization`, and `oci.computeagent.memory_utilization` (or any other Compute metric) and group by `host`. To see Object Storage usage and costs side by side, you can graph `oci.objectstorage.stored_bytes` and `oci.cost.amortized` grouped by `name`.

+Additionally, Datadog provides the following tags that can be used with many observability metrics. For example, to view cost and execution duration of OCI Functions for each compartment, you can make a table with `oci.cost.amortized`, `oci.faas.function_execution_duration`, and group by `compartment_id`.

 ### Container cost allocation
 Container cost allocation is not available for OCI. See [Container Cost Allocation][5] for more details.
