How to monitor memory usage on heroku (node.js)

Question

There is New Relic for Rails, but I could not find anything available for node.js. Is there any tool or an API to monitor memory usage of heroku dynos?

Answer 1

This may not be the full solution you're looking for, but you can get the current memory usage of a Node.js process via process.memoryUsage().

Answer 2

Use node-usage, additionally you can see the CPU usage too.

Answer 3

Although not as full-featured as New Relic, the nodetime npm package (and matching site) does provide memory usage, latency and similar monitoring.
