Hi guys, is there any option that allows me to see what resources are available to create instances? I noticed that default flavors and project quoatas are editable and that can cause problems if we set more resources than we have like error state having 48GB RAM ! So there is a way to see what resources are "realy" available? Thanks!
Hi,
Hope this will help you :
nova hypervisor-stats
It will return the statistics of the Hypervisor node example,
+----------------------+-------+
| Property | Value |
+----------------------+-------+
| count | 2 |
| current_workload | 0 |
| disk_available_least | 1378 |
| free_disk_gb | 1606 |
| free_ram_mb | 47003 |
| local_gb | 1606 |
| local_gb_used | 0 |
| memory_mb | 48027 |
| memory_mb_used | 1024 |
| running_vms | 0 |
| vcpus | 28 |
| vcpus_used | 0 |
+----------------------+-------+
Yes, you can see this also from horizon under Admin->Hypervisors section, but in my experience I've noticed that the real ram usage, launching the "free -mh" command on the computes node, is different from what the above command says. Can you verify this?
@RomilGupta , using nova hypervisor-stats command i got
free_ram_mb = -1510
