restart node.js forever process if response time too big
forever, node.js
Solution
I am assuming you want to restart the server if most of the reply are taking longer than x seconds. There are many tools that helps you to restart your instances based on their health. Monit is one of them. In this guide, monit restart the instance if reply doesn't come back in 10 seconds.
If you want to kill the instance if one request if any of the requests are taking too long, then you note down the time when you take in the request, and note down the time when request leaves. If the time is too long, throw an exception that you know will not get caught and the server would restart by itself. If you use express, then check the code for their logger under development mode, as it tracks the response time.
Problem
I got forever script for managing `node.js` site. Sometimes `node.js` site hangs and response time go above 30 seconds. And in fact site is down. Then fast cure for it is restarting `forever`: ``` $ forever restart 3 ``` where `3` is script number in `forever list`. Is it possible to make it automatically? Is there option in `forever` which make it restart if response time will be more than 2 seconds for example? Or maybe I got to run external script which will check response time and make descension to restart hanging `forever` script. Or maybe I need to write this logic inside my `node.js` site?
