# Oracle Cloud Observability ## Overview Set up programmatic monitoring for OCI infrastructure using the Monitoring, Logging, and Notifications services. The OCI Console buries these features behind nested menus, and the status page has historically failed to acknowledge outages (e.g., London region, January 2026). This skill builds monitoring you control through code — metric queries, alarm rules, custom metric publishing, and log searches — so you are never surprised by an outage you should have caught. **Purpose:** Create a code-driven observability stack that queries metrics, fires alarms, publishes custom metrics, and searches logs without depending on the OCI Console. ## Prerequisites - **OCI tenancy** with an API signing key in `~/.oci/config` - **Python 3.8+** with `pip install oci` - **Compartment OCID** containing the resources to monitor - **IAM policies** granting `manage alarms` and `read metrics` in the target compartment - **Notification topic** created for alarm destinations (or create one in Step 4) ## Instructions ### Step 1: Query Metrics with MonitoringClient OCI publishes built-in metrics for compute, networking, block storage, and more. Query them programmatically: ```python import oci from datetime import datetime, timedelta config = oci.config.from_file("~/.oci/config") monitoring = oci.monitoring.MonitoringClient(config) # Query CPU utilization for all instances in a compartment response = monitoring.summarize_metrics_data( compartment_...
