Hi there,

Surely this is something I am doing wrong, or a result of my inexperience with node, but I can't seem to get this daemon to startup. Forgive me if this is not the best place to post, I could not locate other means of contacting you

root@master:/home/ubuntu/cloudwatch-librato# node ./index.js --config settings.json

node.js:201
throw e; // process.nextTick error, or 'error' event on first tick

/usr/local/bin/node

root@master:~# node --version
v0.6.17

I've tried installing from apt and also from source, and both produce the same error when i run it.

It seems node does work if i start the sample application from their website:
root@master:# cat server.js
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');
root@master:# node server.js
Server running at http://127.0.0.1:1337/

I appreciate any help/advice as this looks like a really fun integration.
