Inspect, Control, Report: HAProxy as the SRE's Door Man

CenterDevice offers secure document storage and sharing with OCR, full text indexing and automatic versioning. Our SREs use HAProxy to gain insights into usage of our services, diagnose issues, and throttle or reject requests based on HAProxy ACLs. In this talk, you will see how we generate HAProxy configuration files using templates. We will describe our custom log format and demonstrate how we integrate HAProxy data with Kibana.
