Redpin, the parent company behind Currencies Direct and TorFX, partnered with Coralogix to build full-stack observability across a £10 billion international payments platform. The architecture uses OpenTelemetry as the connective tissue, linking frontend RUM sessions through distributed traces to Kubernetes pod metrics and logs via W3C TraceContext. Key outcomes include: AI-powered root cause analysis (CX-AI and Olly) reducing RCA time from hours to minutes, structured incident management via Coralogix Cases improving MTTR, real user monitoring surfacing performance regressions invisible to synthetic monitoring, and proactive SLO burn rate alerting. The OTel Collector runs as a DaemonSet with custom OTTL transforms and tail sampling policies capturing 100% of error traces while controlling data volume costs.
