# Heap Stats
|
|
|
|
Heap stats is a HTML-based tool for visualizing V8-internal object statistics.
|
|
For example, the tool can be used to visualize how much heap memory is used for
|
|
maintaining internal state versus actually allocated by the user.
|
|
|
|
The tool consumes log files produced by d8 (or Chromium) by passing
|
|
`--trace-gc-object-stats` or a trace captured using Chrome's tracing
|
|
infrastructure. Chrome trace files can either be processed as gzip or raw text
|
|
files.
|
|
|
|
|
|
Hosting requires a web server, e.g.:
|
|
|
|
cd tools/heap-stats
|
|
python -m SimpleHTTPServer 8000
