Build OCI Events service rules with event type conditions and notification/function actions.
Required Fields
compartmentIddisplayNameconditionactionsOutput will appear here...The builder constructs OCI Events rule configurations: rule resource (display name, condition expression matching service+eventType+resource attributes+tags, actions array with destinations: Functions function OCID, Notifications topic OCID, Streaming stream OCID). Output is generated as oci events rule commands and Terraform oci_events_rule resources.
OCI Events service delivers real-time notifications when resources in your tenancy change state — instances start or stop, buckets are created, users are modified, and hundreds of other operations across OCI services. Events rules match incoming events using attribute filters and route them to actions like OCI Functions, Notifications topics, or Streaming streams. This builder helps you configure event rules with service-based filters, event type conditions, tag-based filtering, and action destinations.
Your security team needs real-time alerting on every IAM policy modification across the org. The builder generates an Events rule: condition matches `eventType=com.oraclecloud.identity.update.policy OR ...add.policy OR ...remove.policy`, action sends to a Notifications topic with PagerDuty + Slack subscriptions plus an OCI Function that logs the change to a tamper-evident audit log. Within seconds of any IAM change, security gets notified with the full event details. Compliance audit closed; real-time IAM monitoring established at zero ongoing cost beyond the Function invocations.
Tag-based filtering is the cleanest pattern for environment-specific automation. Instead of maintaining lists of resource OCIDs in your event rules, tag resources with `environment:production` and filter events on that tag. New production resources are automatically covered by the rule; dev resources are excluded.
Always set Functions as the action for non-trivial event responses. The naive 'send to Notifications, have a human respond' pattern is too slow for time-sensitive automation (e.g., 'auto-revoke compromised credential'). Functions enable sub-second automated response.
Audit log events (the 'admin events' showing IAM changes, resource modifications) are the highest-value events to monitor. Build rules for: IAM policy modifications, identity domain changes, root account activity, and Security Zone violations. These are the events that detect security incidents in real-time.
OCI Events captures resource lifecycle events from nearly every OCI service — Compute (instance start, stop, terminate), Object Storage (object create, update, delete), Networking (VCN, subnet, security list changes), Identity (user, group, policy modifications), Database (DB system state changes), and many more. Each event includes the resource OCID, compartment, event type, timestamp, and additional service-specific details. You can filter events by service, event type, resource OCID, and freeform or defined tags.
Yes. Event rules support tag-based filtering using both freeform tags and defined tags. This lets you create rules that only fire for tagged resources — for example, trigger a notification only when an instance tagged 'environment:production' is stopped. Tag-based filtering is powerful for building environment-specific automation without maintaining lists of resource OCIDs in your rules.
