Pinba is a MySQL storage engine that acts as a realtime monitoring/statistics server using MySQL as a read-only interface. Node-pinba provides client for Pinba server that provides statistics sending from your node.js application.
Check out the Github repo for the source code.
You can install this module via npm:
$> npm install pinba
Node.js is not a bottleneck anymore! Now you can use pinba to measure particular code parts and collect information about requests to your server.
Because Node.js operates in single-threaded event loop and does not orient only for HTTP servers,
there was some differences between this module and original Pinba for PHP. Mostly, there is no
isolate requests in Node.js, so you should take care of creating
for each code chain that you mention as request and call
flush method at response end.
There is a simple example how to capture timer value around database call during request:
var http = ;var PinbaRequest = Request;var db = ;http;
Read this module API docs and original Pinba docs for more information.
Connect Pinba middleware can be founded here. Feel free to write any for other frameworks.
There was some difference between original PHP threaded model and Node.js event-loop requests processing. So not all original Pinba features are supported.
