We use Xenserver and want to do basic Ping checks and cpu, memory, disk, ? We have Nagios in place so I will look to see what level of hypervisor monitoring can be achieved.

It depends on two things: What you're trying to monitor and what hypervisor you have. We've been looking into this subject and we want to poll basic monitoring data (cpu, memory, disk, etc) which can be done at the hypervisor level with the right monitoring tool. To get beyond that and dig down into the guests the only thing we've come up with is by installing/configuring a monitoring agent on all of our templates so that when the template is deployed it will automatically update our monitor with info about the guest VM. I guess you could also look at modifying the virtual router system VM and deploying something on there that would discover all of the VMs, pull from them, and send it back to a central monitoring system. But that adds more work for what is already a pretty light weight installation so it might not be desirable. -Clayton -----Original Message----- From: David Nalley [mailto:da...@gnsa.us] Sent: Wednesday, April 25, 2012 4:50 AM To: cloudstack-dev@incubator.apache.org Subject: Re: Cloudstack Questions Welcome Marlon > > 1) Will NFS be phased out for secondary storage in the future?

Alternatively, you could configure log4j to send logs of warning or higher to syslog - and thus on to some central logging facility like logstash, greylog, or splunk.
