How get some kind of Metrics/Utilization of VM's to working?

[maly-glod]

Hi Guys,

I need Your support or some hints, how to get utilization data working.

1. Describe your environment: ManageIQ: official Petrosian OpenStack version deployed on 4 VMs:
   • 2x Appliance (HA based on high_availability_guide)

     
     Welcome to the ManageIQ Virtual Appliance.

To modify the configuration, use a web browser to access the management page.

Hostname: miq-app-1 IPv4 Address: 10.1.1.11/255.255.255.0 IPv4 Gateway: 10.1.1.1 IPv6 Address:
IPV6 Gateway:
Primary DNS: 10.1.1.4 Secondary DNS: 10.1.1.15 Search Order: os.local MAC Address: fa:16:3e:60:af:ff Timezone: Europe/Warsaw Local Database Server: not initialized ManageIQ Server: running ManageIQ Database: miq-app-4-db Database/Region: vmdb_production / 0 External Auth: xxxxx ManageIQ Version: petrosian-1

Cloud: OpenStack AIO Caracal (stable/2024.1) version deployed on BareMetal host (based on [OpenStack-Ansible Quickstart: AIO](https://docs.openstack.org/openstack-ansible/2024.1/user/aio/quickstart.html)
 - additional services installed (all defaults): 
>  - aodh,

>  - ceilometer,
>  - skyline

On fresh installation ceilometer is no longer registered as endpoint (replaced by Gnocchi??):

2. Describe the issue you are having and what you expected to happen.
I'm having trouble getting/displaying any metrics showing current resource usage (CPU, memory, etc.) on running VM. Can I ask for some advice on how to start collecting this data and get it working? All "tutorials/tips" concern old versions of OpenStack (e.g. Pike) where telemetry was based on a ceilometer and it was registered as OS endpoint.

3. Describe the steps to reproduce, including any log snippets and stack traces that will help diagnose.
As  originally posted by @dikonoor in https://github.com/ManageIQ/manageiq-providers-openstack/issues/199#issuecomment-554250255 

and official documentation: 

Ceilometer previously provided a storage and API solution. As of Newton, this functionality is officially deprecated and discouraged. For efficient storage and statistical analysis of Ceilometer data, Gnocchi is recommended.

I couldn't validate cloud with Ceilometer as events source:

So I decided to try with AMQP:
I had to make DNAT rule on aio1 host to get into rabbitmq-server 5672 port (because it doesn't normally expose it to a "public" ip):

root@aio1:~# iptables -nv -L -t nat Chain PREROUTING (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination
5 300 DNAT tcp -- 0.0.0.0/0 10.13.16.75 tcp dpt:5672 to:172.29.239.196:5672

Unfortunately, connecting directly to Rabbit did not change anything.

And one more thing, based on #295 which refers to [this](https://github.com/ManageIQ/manageiq-ui-classic/pull/5270) thread, there should be 2 AMQP fallback ip fields and there aren't:

Merge is from 2019, shouldn't this be included in the official version of Petrosian?

Hi Maly,

Is the ceilometer generated the metrics ? check it using command openstack metric list and openstack metric resource show

Hi @remo233

Yes ceilometer on my AIO is generating the metrics.
