I am load testing my service (using jMeter). The service works just fine when accessed normally (ie via Swagger).
But when I load test it, it will start giving me 503 responses say "Service Unavailable".
But when I load test using IIS, I don't get that error. I have tried adding a ton more pods (35), but the issue still happens.
While I would love a direct answer, I know that is unlikely. What I am looking for is a way to debug this. How can I get more than "Service Unavailable"?
I need some logs from Istio to see why it is doing this. Is it really just too much for it? Do I need to have 100 pods? Without logs I cannot know.
FYI: My load test has 100 threads that continually call my service for 200 seconds. My service takes the call and directly puts a message on a RabbitMQ server, and then returns.
How can I get more debug information out of Istio?
