Question about simulating problems about concurrency-limits

[spockz]

Latency spikes can be simulated by routing the traffic through a proxy (envoy supports it out of the box and there are many others) or even just on the tcp level with iptables or tc on Linux or throttle/pfctrl on macOS.

Tools such as chaos monkey can be used to simulate resource contention like another process using up all the cpu and ram in a vm. I'm not aware of something doing this in the same JVM process.

@guilherme unfortunately not - it's not been a priority and I haven't had a chance to look at this since. I'd still be interested in knowing good techniques to simulate this though!

Thank you for the hints @spockz I found this video here: https://www.youtube.com/watch?v=CQvmSXlnyeQ you might find interesting @adamconnelly

@adamconnelly hi! did you manage to simulate?

@guilherme thanks for sharing that - the talk was really interesting. It was really cool seeing the graphs from the various test scenarios that were run!
