api gateway

Practical, vendor-agnostic guide to monitor an AI API gateway from Linux using only Bash, curl, jq, and nginx: define SLOs (availability, p95 latency, 429/5xx, timeouts, token cost), enable JSON access logs, turn logs into live counters with jq/awk, run minute-by-minute synthetic probes via systemd, export Prometheus textfile metrics, and trigger lightweight alerts—catching throttles, errors, and cost runaways fast.

A practical guide to automating Nginx or Caddy reverse-proxy configs with a Bash pipeline that queries an OpenAI-compatible LLM, extracts a fenced config, validates (nginx -t/caddy validate), and reloads atomically with rollbacks and systemd timers. Includes a JSON inventory, TLS/auth/rate limiting, apt/dnf/zypper install steps, safety/debug tips, and real-world routing patterns.
