Tinklo monitorius fiksuoja ir rodo kiekvieną dabartinio puslapio tinklo užklausą realiu laiku.
Chrome DevTools skirtukas „Network“ yra galingas, bet gremėzdiškas — jis užima daug ekrano vietos, atsistato pereinant į kitą puslapį ir reikalauja atsitraukti nuo paties puslapio turinio. Network Monitor pateikia svarbiausias tinklo stebėjimo funkcijas lengvame plaukiojančiame skydelyje, kuris yra virš puslapio.
Jis perima XHR ir Fetch užklausas bei stebi išteklių krovimą per Performance API, rodydamas kiekvieną tinklo užklausą jai vykstant. Kiekviena užklausa rodo URL, HTTP metodą (GET, POST, PUT, DELETE), būsenos kodą (pažymėtą spalva: žalia — 2xx, geltona — 3xx, raudona — 4xx/5xx), atsako dydį baitais ir trukmę milisekundėmis. Spustelėkite bet kurią užklausą, kad išplėstumėte jos detales: užklausos antraštes, atsako antraštes, užklausos duomenis (payload), atsako turinio peržiūrą ir laiko išklotinę.
Užklausos, atliktos per Beacon API (dažniausiai naudojamos analitikos signalams siųsti tiesiog prieš puslapiui užsidarant), taip pat fiksuojamos — tai paprastai sunku stebėti, nes jos suveikia navigacijos metu. Tai atskiras įrankis nuo WebSocket Inspector — Network Monitor sutelktas į HTTP užklausų ir atsakų srautą, o WebSocket ryšius ir jų kadrus apima specializuotas WebSocket Inspector įrankis, todėl kiekvienas skydelis lieka sutelktas ir įskaitomas, o ne sumaišo du visiškai skirtingus srauto tipus į vieną triukšmingą sąrašą.
Every network request appears in the panel as it happens — page loads, API calls, lazy-loaded resources, and background fetches. The feed updates in real-time with no manual refresh needed.
Click any request to see full details: request URL, method, headers, payload (for POST/PUT), response headers, response body preview (JSON auto-formatted), status code, size, and timing breakdown.
Filter requests by type: XHR/Fetch (API calls), JS (scripts), CSS (stylesheets), IMG (images), Font (web fonts), or All. Isolate API traffic from resource loading to focus on what matters.
Status codes are color-coded for instant recognition: green for 2xx (success), yellow for 3xx (redirects), red for 4xx (client errors) and 5xx (server errors). Failed requests are immediately visible.
Each request shows the response size (in KB) and total duration (in milliseconds). Identify slow API calls, oversized resources, and unnecessary requests that impact page performance.
A summary bar shows total request count and combined size for all captured requests. Filter the summary to see totals per type — how much bandwidth is spent on scripts vs images vs API calls.
Watch XHR/Fetch requests to verify your frontend is calling the correct API endpoints with the right parameters. Click to inspect request payloads and response bodies — catch mismatched data formats instantly.
Red 404 and 500 entries immediately highlight broken resources or failing API calls. See which URLs are failing, when they fail, and what error response the server returns.
Sort by duration to find the slowest requests. Sort by size to find the largest resources. The summary totals show the full bandwidth picture — is the page making too many requests or downloading too much data?
See what network requests the page makes in the background — analytics pings, heartbeat calls, polling requests, lazy-loaded resources. Understand the full network activity beyond what's visible to the user.
Filter requests and check which domains are being contacted. Identify third-party scripts making unexpected network calls — tracking pixels, data collection, or external API calls you didn't know about.
Open the DevSuite Pro floating dock and click the Network Monitor icon. A panel opens and begins capturing network requests immediately.
Use the page normally. Every network request appears in the feed as it's made — API calls, resource loads, and background fetches are all captured.
Click the type filters (XHR, JS, CSS, IMG, Font) to narrow the view. Show only API calls to debug data fetching, or only images to check asset loading.
Click any request row to expand its details: URL, headers, payload, response body, status code, size, and timing.
Red status codes (404, 500) indicate failed requests. Slow durations flag performance bottlenecks. Large sizes suggest resources that need optimization.
