Tracing provides a mechanism to collect tracing information generated by V8, Node core and userspace code in a log file. Tracing can be enabled by passing the --trace-events-enabled flag when starting a Node.js application.
The set of categories for which traces are recorded can be specified using the --trace-event-categories flag followed by a list of comma separated category names. By default the node and v8 categories are enabled.
node --trace-events-enabled --trace -event-categories v8,node server.js
Running Node.js with tracing enabled will produce log files that can be opened in the chrome://tracing tab of Chrome.
