Tracing

Trace Event provides a mechanism to centralize tracing information generated by V8, Node core, and userspace code.

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, node.async_hooks, and v8 categories are enabled.

node --trace-events-enabled --trace-event-categories v8,node,node.async_hooks server.js

Running Node.js with tracing enabled will produce log files that can be opened in the chrome://tracing tab of Chrome.
