# 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` and `v8` categories are enabled.
|
||
|
|
|
||
|
|
```txt
|
||
|
|
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`](https://www.chromium.org/developers/how-tos/trace-event-profiling-tool)
|
||
|
|
tab of Chrome.
