Monitoring Kong API Gateway

eG Enterprise provides a specialized monitoring for Kong API Gateway.

Figure 1 : Kong API layer model

Each layer of Figure 1 is mapped to a variety of tests pertaining to the Kong API server, Kong API Server, Kong API Data, Kong API Nginx and Kong API Applications layer. Each layer is mapped to specialized tests that track resource utilization, performance metrics, policy enforcement, and availability indicators. Using the metrics reported, administrators can find quick and accurate answers for the following performance questions:

1. Is the Kong API Gateway currently healthy and running?

2. Is latency for any API route exceeding expected thresholds?

3. Are there 5xx errors being returned from upstream services?

4. Is Kong experiencing rate limit violations?

5. Are authentication failures occurring frequently?

6. Is the response time for key endpoints within acceptable limits?

7. Are all plugins (e.g. rate limiting, authentication) working as expected?

8. Has there been a sudden spike in traffic on any route?

9. Is any service or route down or returning consistent errors?

10. Is Kong running out of system resources (CPU, memory)?

11. Are there any unauthorized access attempts detected?

12. Is the database connection (e.g. PostgreSQL, Cassandra) stable?

13. Is TLS termination working correctly?

14. Are custom metrics being collected and exposed properly?

15. Have any alerts been triggered in the last 24 hours?
