Monitoring compute nodes
You can monitor the compute node status on the Compute > Nodes screen. Nodes in the compute cluster can have the following statuses:
- Healthy
- The node operates normally.
- Configuring
- The node configuration (the default CPU model for VMs or the compute role) is changing.
- Fenced
- The node has become available after a failure, it is now fenced from scheduling new VMs on it.
- Critical
- The node has encountered a critical problem and is not operational.
To view compute node details
Admin panel
On the Compute > Nodes screen, click a compute node. You can view the following compute node information:
-
Virtual CPU and RAM reservations:
- Reserved for the system and storage services
- Provisioned to virtual machines located on the node
- Free virtual CPUs and RAM left on the node
The number of virtual CPUs is a product of the number of physical CPUs on a node and the overcommitment ratio. The amount of RAM is a product of the amount of physical RAM on a node and the overcommitment ratio. To learn more about physical CPU and RAM reservations for system and storage services, refer to Server requirements.
- Hosted virtual machines and their resource consumption
Command-line interface
Use the following command:
vinfra service compute node show <node>
<node>- Node ID or hostname
For example, to view the details of the compute node node001, run:
# vinfra service compute node show node001 +---------------+------------------------------------------+ | Field | Value | +---------------+------------------------------------------+ | host | node001.vstoragedomain | | host_ip | 10.37.130.101 | | hypervisor | id: 86f1ca2c-71c7-47a0-9c7f-bb9dd705e67e | | | state: up | | | status: enabled | | | vms: 0 | | id | 7ffa9540-5a20-41d1-b203-e3f349d62565 | | orig_hostname | node001 | | placements | [] | | roles | - controller | | | - compute | | services | - name: cinder-scheduler | | | state: healthy | | | - name: cinder-volume | | | state: healthy | | | - name: neutron-dhcp-agent | | | state: healthy | | | - name: neutron-l3-agent | | | state: healthy | | | - name: neutron-metadata-agent | | | state: healthy | | | - name: neutron-openvswitch-agent | | | state: healthy | | | - name: nova-compute | | | state: healthy | | | - name: nova-conductor | | | state: healthy | | | - name: nova-scheduler | | | state: healthy | | state | healthy | +---------------+------------------------------------------+
