langchain-deploy-integration Deploy a LangChain 1.0 / LangGraph 1.0 app to Cloud Run, Vercel, or LangServe correctly — with timeouts sized for chain length, cold-start mitigation, SSE anti-buffering headers, and Secret Manager over .env. Use when prepping a first production deploy, debugging a stream that hangs behind a proxy, or diagnosing p99 latency spikes. Trigger with "langchain deploy", "langchain cloud run", "langchain vercel python", "langchain langserve", or "langchain docker".

Deepgram Observability
Overview
Full observability stack for Deepgram: Prometheus metrics (request counts, latency histograms, audio processed, cost tracking), OpenTelemetry distributed tracing, structured JSON logging with Pino, Grafana dashboard JSON, and AlertManager rules.
Four Pillars
Pillar Tool What It Tracks Metrics Prometheus Request rate, latency, error rate, audio minutes, estimated cost Traces OpenTelemetry End-to-end request flow, Deepgram API span timing Logs Pino (JSON) Request details, errors, audit trail Alerts AlertManager Error rate >5%, P95 latency >10s, rate limit hits
Instructions
Step 1: Prometheus Metrics Definition

Step 2: Instrumented Deepgram Client import { createClient, DeepgramClient } from '@deepgram/sdk' ;
class InstrumentedDeepgram {
private client : DeepgramClient ;
private costPerMinute : Record <string , number > = {
'nova-3' : 0.0043 , 'nova-2' : 0.0043 , 'base' : 0.0048 , 'whisper-large' : 0.0048 ,
};
constructor (apiKey : string this .client = createClient (apiKey);
}
async transcribeUrl (url : string , options : Record <string , any > = {}const model = options.model ?? 'nova-3' ;
const timer = latencyHistogram.startTimer ({ method : 'prerecorded' , model });
try {
const { result, error } = await this .client .listen .prerecorded .transcribeUrl (
{ url }, { model, smart_format : true , ...options }

const status = error ? 'error' : 'success' ;
timer ();

}
}
connectLive (options : Record <string , any >const model = options.model ?? 'nova-3' ;
activeConnections.inc ();
const connection = this .client .listen .live (options);
const originalFinish = connection.finish .bind (connection);
connection.finish = () => {
activeConnections.dec ();
return originalFinish ();
};
return connection;
}
}
Step 3: OpenTelemetry Tracing import { NodeSDK } from '@opentelemetry/sdk-node' ;
import { OTLPTraceExporter } from '@opentelemetry/exporter-trace-otlp-http' ;
import { getNodeAutoInstrumentations } from '@opentelemetry/auto-instrumentations-node' ;
import { Resource } from '@opentelemetry/resources' ;
import { SEMRESATTRS_SERVICE_NAME } from '@opentelemetry/semantic-conventions' ;
import { trace } from '@opentelemetry/api' ;
const sdk = new NodeSDK ({
resource : new Resource ({
[SEMRESATTRS_SERVICE_NAME ]: 'deepgram-service' ,
'deployment.environment' : process.env .NODE_ENV ?? 'development' ,
}),
traceExporter : new OTLPTraceExporter ({
url : process.env .OTEL_EXPORTER_OTLP_ENDPOINT ?? 'http://localhost:4318/v1/traces' ,
}),
instrumentations : [
getNodeAutoInstrumentations ({
'@opentelemetry/instrumentation-http' : {
ignoreIncomingPaths : ['/health' , '/metrics' ],
},
}),
],
});
sdk.start ();
const tracer = trace.getTracer ('deepgram' );
async function tracedTranscribe (url : string , model : string return tracer.startActiveSpan ('deepgram.transcribe' , async (span) => {
span.setAttribute ('deepgram.model' , model);
span.setAttribute ('deepgram.audio_url' , url.substring (0 , 100 ));
try {
const instrumented = new InstrumentedDeepgram (process.env .DEEPGRAM_API_KEY !);
const result = await instrumented.transcribeUrl (url, { model });
span.setAttribute ('deepgram.duration_seconds' , result.metadata .duration );
span.setAttribute ('deepgram.request_id' , result.metadata .request_id );

return result;
} catch (err : any ) {
span.recordException (err);
span.setStatus ({ code : 2 , message : err.message });
throw err;

Step 4: Structured Logging with Pino import pino from 'pino' ;
const logger = pino ({
level : process.env .LOG_LEVEL ?? 'info' ,
formatters : {
level : (label ) => ({ level : label }),
},
timestamp : pino.stdTimeFunctions .isoTime ,
base : {
service : 'deepgram-integration' ,
env : process.env .NODE_ENV ,
},
});
const transcriptionLog = logger.child ({ component : 'transcription' });
const metricsLog = logger.child ({ component : 'metrics' });
transcriptionLog.info ({
action : 'transcribe' ,
model : 'nova-3' ,
audioUrl : url.substring (0 , 100 ),
requestId : result.metadata .request_id ,
duration : result.metadata .duration ,
confidence : result.results .channels [0 ].alternatives [0 ].confidence ,
}, 'Transcription completed' );
transcriptionLog.error ({
action : 'transcribe' ,
model : 'nova-3' ,
error : err.message ,
statusCode : err.status ,
}, 'Transcription failed' );
Step 5: Grafana Dashboard Panels {
"title" : "Deepgram Observability" ,
"panels" : [
{
"title" : "Request Rate" ,
"type" : "timeseries" ,
"targets" : [ { "expr" : "rate(deepgram_requests_total[5m])" } ]
} ,
{
"title" : "P95 Latency" ,
"type" : "gauge" ,
"targets" : [ { "expr" : "histogram_quantile(0.95, rate(deepgram_request_duration_seconds_bucket[5m]))" } ]
} ,
{
"title" : "Error Rate %" ,
"type" : "stat" ,
"targets" : [ { "expr" : "rate(deepgram_requests_total{status='error'}[5m]) / rate(deepgram_requests_total[5m]) * 100" } ]
} ,
{
"title" : "Audio Processed (min/hr)" ,
"type" : "timeseries" ,
"targets" : [ { "expr" : "rate(deepgram_audio_processed_seconds_total[1h]) / 60" } ]
} ,
{
"title" : "Estimated Daily Cost" ,
"type" : "stat" ,
"targets" : [ { "expr" : "increase(deepgram_estimated_cost_dollars_total[24h])" } ]
} ,
{
"title" : "Active WebSocket Connections" ,
"type" : "gauge" ,
"targets" : [ { "expr" : "deepgram_active_websocket_connections" } ]
}
]
}
Step 6: AlertManager Rules groups:
- name: deepgram-alerts
rules:
- alert: DeepgramHighErrorRate
expr: >
rate(deepgram_requests_total{status="error"}[5m])
/ rate(deepgram_requests_total[5m]) > 0.05
for: 5m
labels: { severity: critical }
annotations:
summary: "Deepgram error rate > 5% for 5 minutes"
- alert: DeepgramHighLatency
expr: >
histogram_quantile(0.95,
rate(deepgram_request_duration_seconds_bucket[5m])
) > 10
for: 5m
labels: { severity: warning }
annotations:
summary: "Deepgram P95 latency > 10 seconds"
- alert: DeepgramRateLimited
expr: rate(deepgram_rate_limit_hits_total[1h]) > 10
for: 10m
labels: { severity: warning }
annotations:
summary: "Deepgram rate limit hits > 10/hour"
- alert: DeepgramCostSpike
expr: >
increase(deepgram_estimated_cost_dollars_total[24h])
> 2 * increase(deepgram_estimated_cost_dollars_total[24h] offset 1d)
for: 30m
labels: { severity: warning }
annotations:
summary: "Deepgram daily cost > 2x yesterday"
- alert: DeepgramZeroRequests
expr: rate(deepgram_requests_total[15m]) == 0
for: 15m
labels: { severity: warning }
annotations:
summary: "No Deepgram requests for 15 minutes"
Metrics Endpoint import express from 'express' ;
const app = express ();
app.get ('/metrics' , async (req, res) => {
res.set ('Content-Type' , registry.contentType );
res.send (await registry.metrics ());
});
Output
Prometheus metrics (6 metrics covering requests, latency, usage, cost)
Instrumented Deepgram client with auto-tracking
OpenTelemetry distributed tracing with custom spans
Structured JSON logging (Pino)
Grafana dashboard panel definitions
AlertManager rules (5 alerts)
Error Handling Issue Cause Solution Metrics not appearing Registry not exported Check /metrics endpoint High cardinality Too many label values Limit labels to known set Alert storms Thresholds too sensitive Add for: duration, tune values Missing traces OTEL exporter not configured Set OTEL_EXPORTER_OTLP_ENDPOINT
