I’m not sure what you want really, client tools to view logs? try: https://github.com/gforcada/haproxy_log_analysis
For request simulation right up to full on load testing try one of these:
Pro’s: Very featureful, you can add host headers, ignore unsecure SSL certs and use them in your own scripts.
Con’s: Will need to write own scripts for anything more than single connection tests.
Automated / Load Testing:
Pro’s: quick and easy way of performing load testing with set number of concurrent users.
Con’s: no advanced features such as graphing as well as other things.
Advanced / Load Testing:
Pro’s: Advanced testing suites with everything you could need from graphing, custom payloads and advanced workload design.
Con’s: Much more complex with a steeper learning curve.
