# Tracing
|
|
|
|
<!--introduced_in=v7.7.0-->
|
|
|
|
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.
|
|
|
|
```txt
|
|
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`](https://www.chromium.org/developers/how-tos/trace-event-profiling-tool)
|
|
tab of Chrome.
