openstack - 如何启用云高仪的“memory.usage”、“disk.usage”、“disk.device.usage”？

Question

我曾经Kolla部署OpenStack，但他们现在没有。 公制

Answer 1

This is not an issue in Kolla and an issue in Ceilometer.

The OpenStack compute service must be configured to use Telemetry. Then, Ceilometer can extract CPU, memory and disk usage from the VMs. Add the following in /etc/nova/nova.conf on all the compute nodes:

[DEFAULT]
...
instance_usage_audit = True
instance_usage_audit_period = hour
notify_on_state_change = vm_and_task_state
compute_monitors= cpu.virt_driver

[oslo_messaging_notifications]
...
driver = messagingv2

I suggest using the latest Ceilometer release (10.0.0 or Queens):
