I am trying to gather some cpu metrics from nova instances on devstack newton.
I am trying to gather some cpu metrics from nova instances on devstack newton.I am employing [JMX] (https://en.wikipedia.org/wiki/Java_Ma... approach, however even after configuring the security group rules to permit the traffic, the connection still fails. Has anyone ever faced/overcome this challenge ? I am also not too sure if there are requisite configuration I have left out.
Is it possible that there is a firewall running in the guest itself? Is other connectivity (e.g. SSH) working end to end?
@sgordon I can ssh into these instances, pinging out for within them is also possible. I have confirmed that there is no firewall. I really don't know what is happening, I also ensured that the security rules are permissive for all HTTP, TCP, ICMP and SSH traffic.
