Node.js Question

Node.js OpsWorks Layer console logs

I have an Opsworks stack with a Node.js Layer and Node.js Application. I'm wondering if anyone knows where on an ubuntu 14.04LTS instance the console logs from my application are being printed to. I know the opsworks uses monit to run my application but i'm not sure where its outputting the logs to.

So annoyingly enough, the Monit configuration rendered for Node.JS apps on Opsworks doesn't send the output anywhere! Source for this claim. (This surprised me when I learned about it!)

What I recommend doing is overriding that template - see the OpsWorks documentation on overriding templates: essentially all you need to do is copy paste the Monit config from Amazon, but change line 2 to redirect the output to a file, like I do below so:

start program = "/bin/bash -c 'cd <%= @deploy[:deploy_to] %>/current ; source <%= @deploy[:deploy_to] %>/shared/app.env ; /usr/bin/env PATH=$PATH:/usr/local/bin PORT=<%= @deploy[:nodejs][:port] %> NODE_PATH=<%= @deploy[:deploy_to] %>/current/node_modules:<%= @deploy[:deploy_to] %>/current /usr/local/bin/node <%= @monitored_script %> &> <%= @deploy[:deploy_to] %>/current/log/production.log'"
