As we all know, NodeJS is very sensitive to memory.

In April last year I used NodeJS to build a marketing project, on the day of project online PV broke one million.

Which is showing a continuous upward trend in memory, in the process of troubleshooting problems, i want to find a lightweight, as long as the visual display of the use of memory tools, but no result.

Then there is the idea of this project, but at that time because of the busy only made a simple Demo to use (Memeye v0.0.3).

Recently there is time, once again turned out to reorganize and revision, add more type of the data display.

For install simply run :

npm install memeye --save-dev
Copy the code

Then require it in your nodejs application

const memeye = require('memeye');
memeye();
Copy the code

Then open your browser and load address:

http://localhost:23333  //23333 port by defaul.
Copy the code

That’s it! No more options, no more config, just so easy.

Collector will wathching and collecting data from the host node process, v8 heap and operrating system, then send the datas to dashboard process with IPC communication channel.

The dashboard , will calling at the child process way. It will create an Indicator instance and start a http server which provide a socket.io instance.

Then bind the indicator with process IPC channel, to recive massage from parent process.

And then bind the indicator with socket.io, to send messages while indicator attrbutes changed.

• Mutil process support
• Report export
