NetLog is an event logging mechanism for Chrome’s network stack to help debug problems and analyze performance. It enables a “capture → dump → analyze” style of workflow similar to tools like tcpdump. Here is a typical use case: User enables network logging. User reproduces a problem. User uploads the log file to a bug report.

NetLog parameters are specified as a JSON serializable base::Value. This has some subtle implications: 1. Do not use base::Value::Type::STRINGwith non-UTF-8 data. 2. Do not use base::Value::Type::BINARY(the JSON serializer can't handle it) Instead: 1. If the string is likely ASCII or UTF-8, use NetLogStringValue(). 2. If the string is arbitrary dat...
NetLog parameters are specified as a JSON serializable base::Valuewhich does not support 64-bit integers. Be careful when using base::Value::SetIntKey()as it will truncate 64-bit values to 32-bits. Instead use NetLogNumberValue().
There is no backwards compatibility requirement for NetLog events and their parameters, so you are free to change their structure/value as needed. That said, changing core events may have consequences for external consumers of NetLogs, which rely on the structure and parameters to events for pretty printing and log analysis. The NetLog viewerfor in...
Add an PROXY_RESOLUTION_SERVICEevent without any parameters, at all capture modes. Analysis: 1. Privacy: Logging the event at all capture modes only reveals timing information. 2. Performance: When not logging, has the overhead of an unconditional function call (BeginEvent), and then a branch (test on IsCapturing()). 3. Size: Minimal data added to ...
Add a FTP_COMMAND_SENTevent, at all capture modes, along with parameters that describe the FTP command. Analysis: 1. Privacy: Low risk given FTP traffic is unencrypted. BuildCommandForString()should additionally best-effort strip any identity information, as this is being logged at all capture modes. 2. Performance: Costs one branch when not captur...
Add a SSL_CERTIFICATES_RECEIVEDevent, along with the full certificate chain, at all capture modes. Analysis: 1. Privacy: Low risk as server certificates are generally public data. 2. Performance: Costs one branch when logging is off (hidden by template expansion). The code in the lambda which builds the base::Valueparameters is only executed when c...
Add a COOKIE_STORE_COOKIE_ADDED event at all capture modes. Moreover, if the capture mode is kIncludeSensitive or kEverything, also logs the cookie's name and value. Analysis: 1. Privacy: The cookie name and value are not included at the kDefaultcapture mode, so only cookie counts and timing information is revealed. 2. Performance: Costs one branch...

2020年4月8日 · The most common (by far) approach to reading NetLogs is to use the Catapult NetLog Viewer, a HTML/JavaScript application which loads the JSON file and parses it into a much more readable set of events. An alternative approach is to use the NetLog Importer for Telerik Fiddler.
chrome has several debugging tools: netlog (chrome://net-internals -> events). see NetLog: Chrome’s network logging system, or the list of netlog events and their meanings. chrome://net-internals/#chromeos -> controls to enable chromeos network debugging and to package up log files.
2020年1月17日 · This method is the easiest way to get a network trace to Microsoft: the JSON is transmitted and stored securely without you having to find a way to encrypt and transfer the data.
A NetLog dump is a log file of the browser's network-level events and state. You may be asked to provide this log when experiencing page load or performance problems. Note: if you want to take a netlog for Android WebView, read this guide instead.
The NetLog model is that long-lived network stack objects, called sources, emit events over their lifetime. A NetLogWithSource object contains a source ID, a NetLogSourceType, and a pointer to the NetLog the source emits events to.
