Make a dump of the V8 heap for later inspection.
npm install heapdump
node-gyp configure build
Load the add-on in your application:
var heapdump = require('heapdump');
The module exports a single, no-arg function called writeSnapshot() that
writes a heapdump-xxxx.xxxx.heapsnapshot file to the application's current
directory.
heapdump.writeSnapshot();
On UNIX, it forks off a new process that writes out the snapshot in an asynchronous fashion. (That is, the function does not block.)
On Windows, however, it returns only after the snapshot is fully written. If the heap is large, that may take a while.
On UNIX platforms, you can force a snapshot by sending the node.js process a SIGUSR2 signal:
$ kill -USR2 <pid>
Open Google Chrome and press F12 to open the developer toolbar.
Go to the Profiles tab, right-click in the tab pane and select
Load profile....
Select the dump file and click Open. You can now inspect the heap snapshot
at your leisure.
