OCI Functions monitoring
Oracle Cloud Infrastructure (OCI) Functions is a serverless platform that lets you run code without managing infrastructure. You organize your code into applications, which serve as containers for your function configurations, networking, and logging resources. You can create functions that contain the actual code logic within the application using OCI Functions.
Overview
Monitoring OCI Functions with Site24x7 ensures your serverless workloads stay reliable, cost-effective, and aligned with business goals. Without active monitoring, errors in function logic, inefficient executions, or misconfigured applications may go unnoticed until they affect customers.
Site24x7 provides real-time visibility into both the application and function layers, enabling quick detection of failures, performance bottlenecks, and scaling issues. This proactive approach helps you minimize downtime, optimize usage costs, and deliver consistent service quality. This integration provides the following two monitors:
- OCI Application: Tracks the overall health and configuration of OCI Functions applications. It collects metadata such as the application’s compartment, networking details, and associated functions.
- OCI Functions: Focuses on individual functions running within an application. Site24x7 captures key metrics such as Function Invocation , Function Responses , and Function Error Responses . This helps you isolate issues, measure function efficiency, and optimize execution costs.
Use cases
- An e-commerce site uses OCI Functions to generate invoices, send email confirmations, and update order statuses. By monitoring both the application and functions in Site24x7, the operations team ensures these workflows run reliably, leading to seamless order processing and improved customer trust.
- A logistics company deploys multiple functions inside an application to manage inventory updates, shipment tracking, and notifications. If the application’s configuration or VCN setup has issues, all functions inside may fail. With Site24x7's integrated OCI Application monitor, the team quickly identifies that the root problem lies at the application level, saving hours of manual troubleshooting.
- A payments team deploys functions to process online transactions. If a sudden code error causes failures in the payment function, Site24x7’s integrated OCI Functions monitor immediately captures the spike in error count and sends alerts. The team can roll back or patch the function quickly, reducing downtime and minimizing impact on customers.
Benefits of Site24x7's OCI Functions integration
Integrate your OCI Functions with Site24x7 and leverage the following benefits:
- Error detection: Get alerts on failures or anomalies in execution trends.
- Cost optimization: Identify inefficient functions that consume excessive time or resources.
- Dependency visibility: Understand how application-level issues may impact multiple functions.
- Proactive monitoring: Catch problems early with automated thresholds and alerting.
Setup and configuration
- Site24x7 uses cross-tenancy access to monitor your resources using Site24x7's tenancy user. Log in to your Site24x7 account, and create a specific policy to allow Site24x7 to view your resources without affecting your security.
- On the Integrate OCI Monitor page, select OCI Functions from the Services to be discovered list.
Policies and permissions
Ensure that the associated OCI policy has the following statement:
- "read functions-family"
Polling frequency
Site24x7 queries OCI service-level APIs according to the set polling frequency (from once a minute to once a day) to collect metrics from the OCI Functions monitors.
