T Jake Luciani commented on CASSANDRA-7838:
-------------------------------------------

Let's come up with another metrics that is a good "Hey you will have 
performance problems" check

Ones I can think of.  

    * Swap enabled.
    * High disk latency
    * Check Ulimits are sensible (sigar has a ulimit check I think)


> Warn user when disks are network/ebs mounted

> It would be nice on start-up to use this to warn users if they are running 
> with settings that will make them sad, like Network drive or EBS on Ec2.
