5 > Stability: 1 - Experimental
7 <!-- source_link=lib/trace_events.js -->
12 Tracing can be enabled with the `--trace-event-categories` command-line flag
13 or by using the `trace_events` module. The `--trace-event-categories` flag
14 accepts a list of comma-separated category names.
19 * `node.async_hooks`: Enables capture of detailed [`async_hooks`][] trace data.
25 * `node.dns.native`: Enables capture of trace data for DNS queries.
27 * `node.fs.sync`: Enables capture of trace data for file system sync methods.
