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".

Webflow Observability
Overview
Full observability stack for Webflow Data API v2 integrations: Prometheus metrics
for API call counting and latency, OpenTelemetry distributed tracing, structured
JSON logging, and alerting rules for error rate and rate limit exhaustion.
Prerequisites
prom-client for Prometheus metrics@opentelemetry/api for tracing (optional)pino for structured loggingPrometheus + Grafana (or compatible backend)
Instructions
Step 1: Prometheus Metrics
import { Registry , Counter , Histogram , Gauge } from "prom-client" ;
export const registry = new Registry ();
export const apiRequests = new Counter ({
name : "webflow_api_requests_total" ,
help : "Total Webflow API requests" ,
labelNames : ["operation" , "status_code" , "method" ] as const ,
registers : [registry],
});
export const apiDuration = new Histogram ({
name : "webflow_api_request_duration_seconds" ,
help : "Webflow API request duration in seconds" ,
labelNames
"operation"

Step 2: Instrumented Client Wrapper
import { WebflowClient } from "webflow-api" ;
import { apiRequests, apiDuration, apiErrors, rateLimitRemaining } from "./metrics.js" ;
export async function instrumentedCall<T>(
operation : string ,
method : string ,
fn : () => Promise <T>
): Promise <T> {
const timer = apiDuration.startTimer ({ operation });
try {
const result = await fn ();
apiRequests.inc ({ operation, status_code : "200" , method });
timer ();
return result;
} catch (error : any ) {
const statusCode = String (error.statusCode || error.status || "unknown" );
apiRequests.inc ({ operation, status_code : statusCode, method });
apiErrors.inc ({
operation,
status_code : statusCode,
error_type : statusCode === "429" ? "rate_limit" : statusCode >= "500" ? "server" : "client" ,
});
timer ();
throw error;
}
}
const { sites } = await instrumentedCall ("sites.list" , "GET" , () =>
webflow.sites .list ()
);
const { items } = await instrumentedCall ("items.listLive" , "GET" , () =>
webflow.collections .items .listItemsLive (collectionId)
);
const item = await instrumentedCall ("items.create" , "POST" , () =>
webflow.collections .items .createItem (collectionId, {
fieldData : { name : "Test" , slug : "test" },
})
);
Step 3: Metrics Endpoint
import express from "express" ;
import { registry } from "../observability/metrics.js" ;
const app = express ();
app.get ("/metrics" , async (req, res) => {
res.set ("Content-Type" , registry.contentType );
res.send (await registry.metrics ());
});
Step 4: OpenTelemetry Distributed Tracing
import { trace, SpanStatusCode , context } from "@opentelemetry/api" ;
const tracer = trace.getTracer ("webflow-integration" , "1.0.0" );
export async function tracedCall<T>(
operationName : string ,
attributes : Record <string , string >,
fn : () => Promise <T>
): Promise <T> {
return tracer.startActiveSpan (`webflow.${operationName} ` , async (span) => {
span.setAttributes ({
"webflow.operation" : operationName,
...attributes,
});
try {
const result = await fn ();
span.setStatus ({ code : SpanStatusCode .OK });
return result;
} catch (error : any ) {
span.setStatus ({
code : SpanStatusCode .ERROR ,
message : error.message ,
});
span.recordException (error);
span.setAttributes ({
"webflow.error.status_code" : String (error.statusCode || "unknown" ),
});
throw error;
} finally {
span.end ();
}
});
}
const { collections } = await tracedCall (
"collections.list" ,
{ "webflow.site_id" : siteId },
() => webflow.collections .list (siteId)
);
Step 5: Structured Logging
import pino from "pino" ;
export const logger = pino ({
name : "webflow-integration" ,
level : process.env .LOG_LEVEL || "info" ,
serializers : {
err : pino.stdSerializers .err ,
},
redact : {
paths : ["accessToken" , "apiToken" , "*.authorization" , "req.headers.authorization" ],
censor : "[REDACTED]" ,
},
});
export function logApiCall (
operation : string ,
durationMs : number ,
status : "success" | "error" ,
metadata ?: Record <string , any >
) {
const logFn = status === "error" ? logger.error .bind (logger) : logger.info .bind (logger);
logFn ({
service : "webflow" ,
operation,
durationMs,
status,
...metadata,
}, `webflow.${operation} ${status} (${durationMs} ms)` );
}
export function logWebhook (triggerType : string , status : "processed" | "failed" | "skipped" info ({
service : "webflow" ,
event : "webhook" ,
triggerType,
status,
}, `webhook.${triggerType} ${status} ` );
}
Step 6: AlertManager Rules
groups:
- name: webflow
rules:
- alert: WebflowHighErrorRate
expr: |
(
rate(webflow_api_errors_total[5m]) /
rate(webflow_api_requests_total[5m])
) > 0.05
for: 5m
labels:
severity: warning
annotations:
summary: "Webflow API error rate > 5%"
description: "{{ $value | humanizePercentage }} errors in last 5m"
- alert: WebflowRateLimited
expr: |
rate(webflow_api_errors_total{status_code="429"}[5m]) > 0
for: 2m
labels:
severity: warning
annotations:
summary: "Webflow API rate limited"
- alert: WebflowHighLatency
expr: |
histogram_quantile(0.95,
rate(webflow_api_request_duration_seconds_bucket[5m])
) > 3
for: 5m
labels:
severity: warning
annotations:
summary: "Webflow P95 latency > 3s"
- alert: WebflowDown
expr: |
sum(rate(webflow_api_requests_total{status_code=~"5.."}[5m])) /
sum(rate(webflow_api_requests_total[5m])) > 0.5
for: 2m
labels:
severity: critical
annotations:
summary: "Webflow API > 50% server errors"
- alert: WebflowRateLimitLow
expr: webflow_rate_limit_remaining < 10
for: 1m
labels:
severity: warning
annotations:
summary: "Webflow rate limit nearly exhausted"
Step 7: Grafana Dashboard Queries {
"panels" : [
{
"title" : "Request Rate by Operation" ,
"targets" : [ { "expr" : "sum by (operation) (rate(webflow_api_requests_total[5m]))" } ]
} ,
{
"title" : "Error Rate" ,
"targets" : [ { "expr" : "sum(rate(webflow_api_errors_total[5m])) / sum(rate(webflow_api_requests_total[5m]))" } ]
} ,
{
"title" : "Latency P50 / P95 / P99" ,
"targets" : [
{ "expr" : "histogram_quantile(0.5, rate(webflow_api_request_duration_seconds_bucket[5m]))" , "legendFormat" : "p50" } ,
{ "expr" : "histogram_quantile(0.95, rate(webflow_api_request_duration_seconds_bucket[5m]))" , "legendFormat" : "p95" } ,
{ "expr" : "histogram_quantile(0.99, rate(webflow_api_request_duration_seconds_bucket[5m]))" , "legendFormat" : "p99" }
]
} ,
{
"title" : "Rate Limit Remaining" ,
"targets" : [ { "expr" : "webflow_rate_limit_remaining" } ]
} ,
{
"title" : "Webhook Events by Type" ,
"targets" : [ { "expr" : "sum by (trigger_type) (rate(webflow_webhook_events_total[5m]))" } ]
}
]
}
Output
Prometheus metrics: request count, latency histogram, error rate, rate limit gauge
OpenTelemetry tracing for end-to-end request visibility
Structured JSON logging with PII redaction
AlertManager rules for error rate, latency, and rate limits
Grafana dashboard panels
Error Handling Issue Cause Solution Missing metrics Calls not instrumented Wrap with instrumentedCall() High cardinality Too many label values Limit operation to known set Trace gaps Missing context propagation Pass OTel context in async calls Alert storms Thresholds too sensitive Increase for duration
