On April 23, 2025, OS Management reaches end of life (EOL). Effective now, the service is no longer available to you in regions where you are not already using OS Management, or to new users with new tenancies. Before the EOL date, we recommend that you migrate your managed instances to the OS Management Hub service. If you are an Oracle Autonomous Linux user, see Important Maintenance Event. For more information, see the Service Change Announcement.
This topic describes the metrics emitted by the OS Management
service in the oci_osms metric namespace.
Resources: managed instances
Overview of Metrics for an Instance and Related Resources
The OS Management service metrics help you measure the number of active and inactive
managed instances, managed instances with available security updates, and managed
instances with available updates.
Prerequisites 🔗
IAM policies: To monitor resources, you must be given 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 and the resources being
monitored. If you try to perform an action and get a message
that you don't have permission or are unauthorized, confirm
with your administrator the type of access you've been granted
and which compartment. For more information on
user authorizations for monitoring, see the Authentication and
Authorization section for the related service:
Monitoring
or
Notifications.
For more information about the policy statement required to access metrics
emitted by OS Management, see Required IAM Policies.
The metrics listed on this page are automatically available
for any managed instance you create. You do not need to enable
monitoring on the resource to get these metrics.
