What should you check first if you notice a missing resource in OCI?

When you notice a missing resource in Oracle Cloud Infrastructure (OCI), one of the most effective first steps is to navigate to the Audit console to check for any delete actions. The Audit service in OCI records all the API calls made to the resources in your account, including actions like creating, modifying, or deleting resources. By reviewing this audit trail, you can identify if the resource was deleted, who performed the action, and when it occurred. This information is crucial because it allows you to determine whether the resource was intentionally removed or if there was an issue that needs to be addressed.

Reviewing the Audit console can save time by providing immediate insights into the actions that have affected your resources. This proactive approach helps in troubleshooting and understanding the current state of your cloud environment.

In contrast, verifying your resources in the Management Console can confirm if a resource is missing, but it won't provide context about its deletion or modification. Checking service limits is important for confirming capacity, but it won’t address instances where resources were removed. Contacting Oracle support might be necessary if you can't determine the cause on your own, but it's usually more efficient to check the audit logs first to gather initial insights.
