Groq Observability
Overview
Monitor Groq LPU inference for latency, token throughput, rate limit utilization, and cost. Groq's defining advantage is speed (280-560 tok/s), so latency degradation is the highest-priority signal. The API returns rich timing metadata (queue_time, prompt_time, completion_time) and rate limit headers on every response.
Prerequisites
A Groq account with an API key exported as the GROQ_API_KEY environment variable — the groq-sdk client reads it automatically (new Groq()).
Node.js with groq-sdk and prom-client installed (npm install groq-sdk prom-client).
A Prometheus scrape target and (optionally) Grafana for the dashboard panels.

Instructions
Apply these six steps in order. Steps 1-2 are the core instrumentation loop —
wrap the client, then feed a Prometheus instrument set from each call. Steps 3-6
add rate-limit tracking, alerting, structured logs, and dashboards on top. The
lean client skeleton is below; the full code for every step lives in
references/implementation.md.
Instrumented client — wrap groq.chat.completions.create so latency, tokens, queue time, and estimated cost are captured on the same path as the request ().
trackedCompletion
Prometheus metrics — register a histogram (latency), counters (tokens, cost, errors), and gauges (throughput, rate-limit remaining), then feed them from emitMetrics.
Rate limit header tracking — parse x-ratelimit-remaining-* off every response into a gauge so you alert before a 429, not after.
See references/implementation.md for the complete
GroqMetrics shape, pricing table, Prometheus instruments, rate-limit tracking,
alert rules, structured logging, and dashboard panel list.
Output
Applying the workflow produces:
A trackedCompletion wrapper that returns { result, metrics }, where metrics is a GroqMetrics object (latency, TTFT, tokens/sec, token counts, queue time, estimated cost).
A Prometheus metric set — groq_latency_ms (histogram), groq_tokens_total / groq_cost_usd / groq_errors_total (counters), and groq_tokens_per_second / groq_ratelimit_remaining (gauges).
Five alert rules (GroqLatencyHigh, GroqRateLimitCritical, GroqThroughputDrop, GroqErrorRateHigh, GroqCostSpike).
A structured JSON log line per request and a 7-panel dashboard spec.
Examples
Instrument a single completion and emit a structured log line:
const { result, metrics } = awaittrackedCompletion(
"llama-3.3-70b-versatile",
[{ role: "user", content: "Summarize this incident report in two sentences." }]
);
logGroqRequest(metrics, result.id);
// metrics.tokensPerSec -> 310, metrics.estimatedCostUsd -> 0.000404
