I have a dozen load balanced cloud servers all monitored by Munin.
I can track each one individually just fine. But I'm wondering if I can somehow bundle them up to see just how much collective CPU usage (for example) there is among the cloud cluster as a whole.
How can I do this?
The munin.conf file makes it easy enough to handle this for subdomains, but I'm not sure how to configure this for simple web nodes. Assume my web nodes are named, web_node_1 - web_node_10.
My conf looks something like this right now:
[web_node_1] address 10.1.1.1 use_node_name yes ... [web_node_10] address 10.1.1.10 use_node_name yes
Your help is much appreciated.
