It records messages and lets you download them as JSON. For repeatable diagnostics, attach a CDP client to the correct target, subscribe to the protocol domains you need (such as Network or Log), and write timestamped events to a file. If your question is only about HTTP traffic, export a HAR from the Network panel instead: a HAR is a network archive, not a complete CDP transcript.
Choose the artifact before you start
| Need | Use | Output |
|---|---|---|
| Inspect commands and responses exchanged through CDP | DevTools Protocol Monitor | Recorded protocol messages downloadable as JSON |
| Debug HTTP requests, responses, and failed loads | Network panel | Request log or HAR export |
| Collect network lifecycle data in a test or service | CDP client with the Network domain enabled | Your own event log |
| Collect browser console and runtime log entries | CDP client with the Log domain enabled | Log.entryAdded records |
| Capture from an extension | chrome.debugger |
Supported CDP commands and events for an attached target |
A Protocol Monitor JSON file answers “what protocol messages were sent and received?” A HAR answers “what network transactions occurred?” Do not label one as the other.
Record CDP messages with Protocol Monitor
- Open Chrome DevTools for the page or target you are investigating.
- If the tool is missing, open DevTools Settings, select Experiments, enable Protocol Monitor, and reopen DevTools.
- Open the Command menu with Ctrl+Shift+P on Windows, Linux, or ChromeOS, or Command+Shift+P on macOS. Search for Protocol monitor and open it. You can also use More options → More tools → Protocol monitor.
- Open the monitor before reproducing the bug. It begins recording when opened and, according to Chrome’s documentation, continues recording across a page reload and even if DevTools closes.
- Reproduce the exact action. Use the clear control first if earlier traffic would make the transcript noisy.
- Inspect a Method, Request, or Response cell to view its details.
- Download the recording as JSON and preserve the browser version and reproduction steps beside it.
This is the most direct built-in workflow for a protocol transcript. It is not a complete browser-process trace, and it does not guarantee that every worker, frame, or internal browser event appears in the same view.
See Chrome’s procedural reference for the current UI: Protocol monitor: View and send CDP requests.

Capture network events programmatically
For automation, the reliable pattern is: attach to the intended target, register listeners before reproducing the action, enable the domain, and stream events with correlation fields. The Network reference documents events including Network.requestWillBeSent, Network.responseReceived, Network.loadingFinished, and Network.loadingFailed (Network domain reference).
- Attach to the right target. A tab, iframe, worker, and service worker can have different targets or sessions. Do not assume a tab-level listener sees every target.
- Install handlers first. Register callbacks before sending
Network.enableand before the test action, otherwise early events can be lost. - Enable the domain. Send
Network.enablethrough your client. - Reproduce the behavior. Keep the request ID, loader or frame identifiers, timestamps, URL, method, status, and error fields that you need to join a lifecycle.
- Write incrementally. Newline-delimited JSON (one event per line) is practical for long sessions; rotate or cap files to prevent an unbounded capture.
- Fetch bodies only when needed. After a response has an ID, call
Network.getResponseBody. That command retrieves a body for a request ID; it is not a substitute for recording the event stream, and body availability depends on the request and target state.
attach to the page target
register handlers for:
Network.requestWillBeSent
Network.responseReceived
Network.loadingFinished
Network.loadingFailed
send Network.enable
reproduce the action
append {timestamp, event, requestId, selected fields} as NDJSON
when required, call Network.getResponseBody(requestId)
close or rotate the logThe exact method names for attaching, subscribing, and dispatching differ between Puppeteer, Playwright, Selenium, and other clients. Treat the outline as protocol logic, then check the client’s documentation and the browser’s matching protocol version rather than copying a library-specific call as universal syntax.
Capture browser log entries with the Log domain
Console and browser log records are separate from HTTP traffic. Enable the Log domain and process Log.entryAdded. The protocol specifies that Log.enable also delivers entries collected so far through that event. Consult the live Log domain reference for fields and command details.
Store the entry’s timestamp, level, source, text, URL, line and column where supplied, and any stack information. Keep this file separate from Network events or add an explicit domain field so downstream tools can distinguish them.

Export a HAR when the problem is network-only
- Open DevTools and select Network before reproducing the action.
- Ensure recording is active. Enable preservation across page loads when your scenario navigates.
- Reproduce the request, inspect timing, headers, status, and response details, then export a HAR from the panel.
Chrome’s Network panel overview documents the current controls. Choose HAR for exchange with HTTP-session tools or request-level analysis; choose Protocol Monitor JSON when you need CDP methods and responses themselves.
Automation, versions, and target scope
CDP is powerful but version-sensitive. Selenium describes its CDP interface as temporary while WebDriver BiDi is implemented, warns that CDP was not designed as a stable testing API, and notes that functionality depends heavily on browser version. Dynamically generated bindings may need updates for the protocol version in use (Selenium Chrome DevTools Protocol documentation).
- Record the Chrome/Chromium version, automation-library version, operating system, and target type with every capture.
- Pin versions in reproducible tests and check the matching protocol reference before relying on a command.
- Playwright and Puppeteer provide CDP-session abstractions, but APIs vary by library, browser, target, and release; do not present one library’s syntax as generic CDP.
- For unusual iframes, workers, or service workers, explicitly discover and attach to their targets or sessions.
Use a Chrome extension as an alternate transport
An extension can attach to a tab with chrome.debugger, send CDP commands, and listen for events. Declare the debugger permission in the manifest. Chrome restricts which protocol domains the API exposes, and enterprise policy can block attachment. Target types and frame-to-target relationships are not always one-to-one, so design the extension around the documented target model. See the chrome.debugger API reference.
Make captures useful and safe
- Start early: enable domains and handlers before the trigger, not after a failure.
- Correlate: retain request IDs and timestamps; include frame, loader, session, and target identifiers when available.
- Bound storage: stream and rotate high-volume logs; body payloads can be substantially larger than event metadata.
- Redact before sharing: URLs, headers, cookies, authorization values, identifiers, and page content may be sensitive. Remove secrets and avoid publishing raw session files.
- Preserve context: record the exact reproduction, browser build, client version, and whether cache, service workers, or extensions were enabled.

The log misses the first request
You opened the monitor or installed handlers after navigation began. Clear the log, start capture first, then reload or reproduce the action.
You see network requests but no CDP methods
The Network panel and Protocol Monitor produce different artifacts. Open Protocol Monitor for commands and responses; use the Network domain in a CDP client for automated events.
A response body cannot be retrieved
Network.getResponseBody needs the correct request ID and a body still available to that target/session. Capture the response event, call the method promptly, and handle failures for redirects, cached items, blocked requests, and targets that have closed.
Events disappear from an iframe or worker
Attach to the relevant target or session and include its identifier in your records. A tab listener is not proof that every related target is covered.

A Selenium command breaks after a browser upgrade
Check the Chrome and Selenium versions and the matching CDP domain schema. CDP compatibility is not a stable cross-version contract; pin versions or migrate appropriate workflows toward WebDriver BiDi.
An extension cannot attach
Verify the manifest’s debugger permission, target eligibility, and enterprise policies. Managed devices can prohibit debugger attachment, and unsupported domains cannot be enabled through this API.

Frequently Asked Questions
Can Protocol Monitor capture traffic from a different Chrome tab?
Open DevTools for the specific page or target you need; target and session scope determine which messages are visible.
Should I save JSON or HAR?
Save Protocol Monitor JSON for CDP commands and responses, and HAR for HTTP request and response analysis.
Is CDP suitable as a long-term test API?
It is version-sensitive; record browser and client versions, and consider WebDriver BiDi for standards-based automation where it meets your requirements.
Are captured logs safe to upload to a bug tracker?
Not automatically. Inspect and redact cookies, authorization headers, identifiers, URLs, and page content first.
