Monitoring / Utilization tab remains disabled for OpenStack (Gnocchi) in Radjabov despite C&U enabled

[dhamo-ror]

Description

In ManageIQ Radjabov, we are using OpenStack with Gnocchi for metrics.
Gnocchi connectivity works from the Rails console, but the Monitoring / Utilization tab in the UI remains greyed out and no metrics or graphs are shown.

---

Environment

• ManageIQ version: Radjabov
• Provider: OpenStack
• Metrics service: Gnocchi

---

What Works

Gnocchi metrics are accessible from the Rails console:

ems = ManageIQ::Providers::Openstack::CloudManager.first
vm  = ems.vms.first

gnocchi_client = ems.connect(:service => "Metric")
gnocchi_client.list_meters([{"field" => "resource_id", "value" => vm.ems_ref}])

Valid meters (cpu, memory, vcpus, disk, etc.) are returned.

---

Issue

• Monitoring / Utilization tab is greyed out

• No metrics are shown:

  • On the OpenStack provider
  • On powered-on VMs

---

Steps Already Tried

1. Enabled Capacity & Utilization (C&U) in Region Settings
2. Restarted ManageIQ appliance
3. Checked Monitoring tab on powered-on VMs
4. Waited more than one week for rollups

Issue still persists.

---

Expected Behavior

Monitoring / Utilization tab should be enabled and display metrics when:

• C&U is enabled
• Gnocchi metrics are available

---

Actual Behavior

Monitoring / Utilization tab remains disabled and no metrics are shown.

@dhamo-ror bunch of initial questions:
Do you have a openstack metrics collector worker running?
If so, do you see that worker logging anything?
Do you have all 3 C&U roles enabled?
Do you have capture for all clusters and datastores enabled in the Region / C&U settings per the documentation

[agrare]

Also I would expect this to only impact cpu metrics, but this fix isn't on radjabov only spassky: #923

[dhamo-ror]

Metrics collector worker is running, I'll update the log status tomorrow, 3 C&U roles are enabled, capture for all clusters and datastores also enabled Adam

[agrare]

One last role question, do you have the scheduler role enabled on any appliances in the zone that your openstack is in?

Hi @agrare, I have the below configs:
