OCI Service Gateway monitoring
The Service Gateway in Oracle Cloud Infrastructure (OCI) allows private access to Oracle services from within your virtual cloud network (VCN) without exposing resources to the public internet. This helps maintain security while ensuring seamless connectivity for workloads running in OCI.
Site24x7 automatically discovers and monitors your OCI Service Gateways across compartments. It tracks their availability, connectivity status, and configuration changes. With continuous polling and metrics collection, you can detect performance issues early, stay informed about service accessibility, and troubleshoot faster.
Overview
Integrating Site24x7 with OCI Service Gateway lets you monitor the availability, performance, and usage of your service gateway endpoints in real time. This is important because service gateways are often a critical link for accessing services like Object Storage, Autonomous Database, or other Oracle services from private subnets.
Any downtime or performance issue in the gateway can disrupt data transfers, application workflows, or analytics jobs relying on these services. Monitoring ensures you detect problems early, maintain service reliability, and avoid costly downtime.
Use case
Consider a financial services company running critical applications in a VCN that need constant access to Oracle Object Storage through an OCI Service Gateway. Any downtime or misconfiguration could disrupt access, impact transactions, or delay customer services.
With Site24x7’s Service Gateway monitoring, the IT team gets real-time alerts on connectivity issues or status changes. They can quickly identify whether the problem is due to the gateway or a configuration update and fix it before it affects business operations.
Benefits of Site24x7's service gateway integration
Integrate your service gateway with Site24x7 and leverage the following benefits:
- Proactive monitoring: Detect gateway downtime or performance degradation before it impacts applications.
- Enhanced visibility: Track metrics like availability, latency, and traffic for informed troubleshooting.
- Secure operations: Maintain private access to OCI services without exposing endpoints to the public internet.
- Reduced downtime: Mitigate business disruptions with faster incident response.
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 Service Gateway from the Services to be discovered list.
Policies and permissions
Ensure that the associated OCI policy has the following statement:
- "read service-gateways"
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 Service Gateway monitor.
