Giant Log Lenses: Testing Wide Content

Giant Log Lenses: Testing Wide Content

When dashboards hide detail, I still go back to raw logs and text-first tools.
This short note is intentionally built as a rendering stress test: some code lines are much wider than the article window to verify horizontal scrolling behavior. The examples are realistic enough to copy, but the primary goal is visual QA for long literals, long command chains, and dense tabular output.

1-liner (intentionally very long)

1

rg --no-heading --line-number --color=never "timeout|connection reset|tls handshake|upstream prematurely closed" ./logs/production/edge/*.log | jq -R 'split(":") | {file:.[0], line:(.[1]|tonumber), message:(.[2:]|join(":"))}' | awk 'BEGIN{FS="|"} {printf "%-42s | L%-6s | %s\n",$1,$2,$3}' | sort -k1,1 -k2,2n

2-liner (wide structured print)

1
2

rows=[{"ts":"2026-02-22T04:31:55Z","service":"api-gateway-eu-central-1-prod-blue","endpoint":"/v1/orders/checkout/recalculate-shipping-and-tax","latency_ms":912,"trace":"9f58b69b2d7d4a21a3f17d5e4f7a0112"}]
print("\n".join(f"{r['ts']} | {r['service']:<36} | {r['latency_ms']:>4}ms | {r['endpoint']} | trace={r['trace']}" for r in rows))

4-liner (wide payload path)

1
2
3
4

const payload = {tenant:"northwind-enterprise-platform",env:"production-eu-central-1",featureFlags:["long-session-replay-streaming","websocket-fallback-polling","incremental-checkpoint-serializer-v2"],meta:{requestId:"4b1d3be8fd7e4ad6a9f8c71e2bbf9a44",userAgent:"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 Chrome/124.0.0.0 Safari/537.36"}};
const digest = btoa(JSON.stringify(payload)).replace(/\+/g,"-").replace(/\//g,"_").replace(/=+$/,"");
const url = `https://collector.example.internal/v2/telemetry/ingest/really/long/path/that/keeps/going?tenant=${payload.tenant}&env=${payload.env}&digest=${digest}`;
fetch(url,{method:"POST",headers:{"content-type":"application/json","x-trace-id":"4b1d3be8fd7e4ad6a9f8c71e2bbf9a44"},body:JSON.stringify(payload)});

If this article behaves correctly, code blocks and tables stay on one logical line and can be scrolled horizontally without breaking the text grid style.
