Collect baseline latency data during periods of low call volume. Compare with latency during peak call volume to quantify the impact.
Obtain the current rate limit settings and evaluate if they are sufficient to handle peak traffic.
Determine if API responses are being cached and if the cache is functioning effectively. Inspect cache hit/miss ratios to determine effectiveness.
The UPark API likely relies on a finite pool of resources (CPU, memory, database connections) within its hosting environment. A surge in customer service calls may indirectly indicate a parallel surge in API requests, potentially overwhelming the available resources. API rate limiting, DNS propagation delays, token validation overhead, and caching inefficiencies contribute to processing delays.
While diagnosing API performance, avoid activities that could further stress the system, such as running excessive queries or making configuration changes without proper testing. If any server needs restarting, follow Safe Handling procedures and ensure a scheduled maintenance window to avoid disruption. Ensure environmental controls (temperature, humidity) are within acceptable operational ranges for server infrastructure to prevent hardware-related issues.
Examine API response headers for caching directives (Cache-Control, Expires) to diagnose caching issues. Implement client-side caching where applicable to reduce server load. Consider leveraging a Content Delivery Network (CDN) to distribute API responses geographically.
