Segment 10
This sub-session finalized Milestone 02 (Enterprise Grade) for the FGW distributed storage system. After previously setting up Loki/Promtail Ansible roles, the user completed the remaining enterprise-grade features: wallet backup and YugabyteDB backup Ansible roles with cron automation, a full backup playbook, Prometheus recording rules, and five detailed Grafana dashboards (overview, S3-SLA, deals, storage, financials). Six operational runbooks were written covering common issues, wallet recovery, database recovery, deal troubleshooting, capacity expansion, and emergency procedures. The AI support system was built as a LangGraph agent with self-hosted Mistral/Ollama models, including knowledge base ingestion and diagnostic tools. All work was committed under a single commit, and subsequent verification steps included integration testing with the Docker test harness, Ansible syntax validation, and adding comprehensive test coverage for GC, balance metrics, and deal metrics code, with careful singleton pattern usage to avoid Prometheus metric conflicts.
