How to configure munin to run on nginx instead of apache

Question

I have couple of production ubuntu 10.04 ec2 instances which are running ruby on rails web app using NGINX. I need to deploy munin for the production servers to monitor it. But the thing is I tried couple of examples suggested by google. I have DNS parked in Route 53. SO how do I enable munin to monitor and how do I get the graph via HTTP.

And also my another question is there any way to monitor my AWS MYSQL RDS using munin. If yes give me heads up.

Thanks

Answer 1

Munin generates a set of static HTML files, normally to /var/cache/www/munin. You can set up nginx to point to this directory or set up a static subdomain with its root set to this domain:

server {
    listen       *:80;
    server_name  munin.yourdomain.com;

    root   /var/cache/munin/www;

    [...other options go here...]

}

For your second question, you can of course monitor RDS instances like any other mysql instances. Just use a mysql plugin of your choice (for example the munin-mysql set of plugins) and point the connection string of the plugin to your RDS instance (in case of munin-mysql this should go in mysql.conf). Often these plugins are already available as a package for your distribution, too. Also make sure that the server you are running the plugin on is allowed to connect to RDS and has the necessary database privileges available.
