Count number of hosts per network
I am trying to calculate number of hosts connected to a specific network in openstack. Is there any efficient way to do so ?
KIndly Help.
You can add --ip <ip-address-regex>, thereby filtering for certain IP addresses. This may enable you to narrow the list down to the servers connected to one network, or at least fewer networks. Whether it's really faster, I don't know.

What do you mean by "host"? If you mean instances, run
openstack server list --all-projectsand use the Networks column to count instances per network.Hi Bernd, this command gives all nodes. What I am trying to do is count hosts attached to a specific network-id. The process of using openstack server list --all-projects would be very inefficient, I think.
