Hi all,
I’m using Kong 1.4 with Prometheus plugin and need help understanding the latency metrics of my services.
The plugin indicates that:
Latencies Histograms : Latency as measured at Kong:
- Request : Total time taken by Kong and Upstream services to serve requests.
- Kong : Time taken for Kong to route a request and run all configured plugins.
- Upstream : Time taken by the Upstream service to respond to requests.
So I thought that the Request latency was the sum of the Kong and Upstream latencies but on my Grafana dashboard I’m seeing a great divergence on these latencies:
How can I find what’s causing the difference between the Upstream and Request times?
Thank you
