Vercel Observability
Overview
Configure comprehensive observability for Vercel deployments using built-in analytics, runtime logs, log drains to external providers, OpenTelemetry integration, and custom instrumentation. Covers the full observability stack from function-level metrics to end-user experience monitoring.
Prerequisites
Vercel Pro or Enterprise plan (for log drains and extended retention)
External logging provider (Datadog, Axiom, Sentry) — optional
OpenTelemetry SDK — optional
Instructions
Step 1: Enable Vercel Analytics
In the Vercel dashboard:
Go to Analytics tab
Enable Web Analytics (Core Web Vitals, page views)
Enable Speed Insights (real user performance data)
import { Analytics } from '@vercel/analytics/react' ;
import { SpeedInsights } from '@vercel/speed-insights/next' ;
export default function RootLayout ({ children } ) {
return (
<html >
<body >
{children}
<Analytics />
<SpeedInsights />
</body >
</html > Install: npm install @vercel/analytics @vercel/speed-insights
Step 2: Runtime Logs
vercel logs https://my-app.vercel.app --follow
vercel logs https://my-app.vercel.app --level=error
"Authorization: Bearer $VERCEL_TOKEN "
"https://api.vercel.com/v2/deployments/dpl_xxx/events?limit=50&direction=backward"
'.[] | {timestamp: .created, level: .level, message: .text}'
Function invocation start/end with duration
console.log/warn/error output from functionsEdge Middleware execution logs
HTTP request/response metadata
Step 3: Structured Logging in Functions
interface LogEntry {
level : 'info' | 'warn' | 'error' ;
message : string ;
requestId ?: string ;
duration ?: number ;
[key : string ]: unknown ;
}
export function log (entry : LogEntry void {
const output = JSON .stringify ({
...entry,
timestamp : new Date ().toISOString (),
region : process.env .VERCEL_REGION ,
env : process.env .VERCEL_ENV ,
});
switch (entry.level ) {
case 'error' : console .error (output); break ;
case 'warn' : console .warn (output); break ;
default : console .log (output);
}
}
export async function GET (request : Request const requestId = crypto.randomUUID ();
const start = Date .now ();
try {
const data = await fetchData ();
log ({ level : 'info' , message : 'Fetched data' , requestId, duration : Date .now () - start });
return Response .json (data);
} catch (error) {
log ({ level : 'error' , message : 'Data fetch failed' , requestId, error : String (error) });
return Response .json ({ error : 'Internal error' , requestId }, { status : 500 });
}
}
Step 4: Log Drains (External Providers) Configure log drains to send all Vercel logs to your logging provider:
In dashboard: Settings > Log Drains > Add
Provider Type Setup Datadog HTTP API key + site URL Axiom HTTP API token + dataset Sentry HTTP DSN Custom HTTP/NDJSON Any HTTPS endpoint Grafana Loki HTTP Push URL + auth
Runtime logs : function invocations, console outputBuild logs : build step output, warnings, errorsStatic logs : CDN access logs (edge)Firewall logs : WAF events
curl -X POST "https://api.vercel.com/v2/integrations/log-drains" \
-H "Authorization: Bearer $VERCEL_TOKEN " \
-H "Content-Type: application/json" \
-d '{
"name": "my-datadog-drain",
"type": "json",
"url": "https://http-intake.logs.datadoghq.com/api/v2/logs",
"headers": {"DD-API-KEY": "your-datadog-api-key"},
"sources": ["lambda", "edge", "build", "static"]
}'
Step 5: OpenTelemetry Integration
import { NodeSDK } from '@opentelemetry/sdk-node' ;
import { OTLPTraceExporter } from '@opentelemetry/exporter-trace-otlp-http' ;
import { getNodeAutoInstrumentations } from '@opentelemetry/auto-instrumentations-node' ;
export function register (const sdk = new NodeSDK ({
traceExporter : new OTLPTraceExporter ({
url : process.env .OTEL_EXPORTER_OTLP_ENDPOINT ,
}),
instrumentations : [getNodeAutoInstrumentations ()],
serviceName : 'my-vercel-app' ,
});
sdk.start ();
}
module .exports = {
experimental : {
instrumentationHook : true ,
},
};
Step 6: Error Tracking with Sentry npx @sentry/wizard@latest -i nextjs
import * as Sentry from '@sentry/nextjs' ;
Sentry .init ({
dsn : process.env .NEXT_PUBLIC_SENTRY_DSN ,
environment : process.env .VERCEL_ENV ,
release : process.env .VERCEL_GIT_COMMIT_SHA ,
tracesSampleRate : process.env .VERCEL_ENV === 'production' ? 0.1 : 1.0 ,
});
Monitoring Dashboard Checklist Metric Source Alert Threshold Error rate Runtime logs > 1% of requests P95 function latency Vercel Analytics > 2s Cold start frequency Runtime logs > 20% of invocations Build success rate Build logs Any failure Core Web Vitals (LCP) Speed Insights > 2.5s Edge cache hit rate Static logs < 80%
Output
Vercel Analytics and Speed Insights enabled
Structured JSON logging in all functions
Log drains configured to external provider
Error tracking with Sentry or equivalent
OpenTelemetry tracing for distributed systems
Error Handling Error Cause Solution Logs missing Log retention expired (1hr free, 30d with Plus) Enable log drains for persistence Analytics not tracking Missing <Analytics /> component Add to root layout Log drain not receiving Wrong URL or auth headers Test the endpoint directly with curl Sentry not capturing errors DSN not set in production env Add NEXT_PUBLIC_SENTRY_DSN to Production scope OTEL traces missing instrumentation.ts not loaded Enable instrumentationHook in next.config.js
