Description Gajanan 2015-10-20 22:33:59 UTC 
======= RFE Request ========

1. Proposed title of this feature request  

> Monitoring Guest CPU steal from the Hypervisor
      
      
3. What is the nature and description of the request?  
      
> Customer wants to have the  CPU steal for a vm reported on the on the RHEV-M portal as they want to monitor the CPU-steal within the guest VMs from the hypervisor. 

    
4. Why does the customer need this? (List the business requirements here)  

Customer mentioned:

> We have a several fairly heavily loaded RHEV clusters.  While we collect statistics at the VM level for some of the environments, we don't collect statistics for our "self-service" dev clusters.
We would like to be able to monitor for CPU-steal within the guest VMs from the hypervisor.  
      
    
5. How would the customer like to achieve this? (List the functional requirements here)  

> RHEV-M should report %steal for a vm on the RHEV-M portal. It would be very useful to be able to see the CPU steal from within RHEV-M (either just the APIs or the Web GUI too)
    
    
6. For each functional requirement listed, specify how Red Hat and the customer can test to confirm the requirement is successfully implemented.  
      
    
7. Is there already an existing RFE upstream or in Red Hat Bugzilla ? 

- No 
      
    
8. Does the customer have any specific timeline dependencies and which release would they like to target (i.e. RHEL5, RHEL6)?  
      
    
9. Is the sales team involved in this request and do they have any additional input?  
      
    
10. List any affected packages or components.  
      
    
11. Would the customer be able to assist in testing this functionality if implemented?

Shirly, do we store in Elastic the steal time via the CPU plugin?
Comment 6 Shirly Radco 2017-12-10 12:03:55 UTC 
No. We currently only report system and user for vms.

Steal time is reported on the host. Please check if it's available on the CPU plugin and if it can be added.
Comment 8 Shirly Radco 2017-12-11 07:30:04 UTC 
We collect cpu usage percent by states - steal, interrupt, user, wait, nice, softirq, system, idle.

Excellent - can you attach a screenshot of such an example (even on the Elastic level) and move this to ON_QA for 4.2?

Hi,
Shirly screenshots are taken from openshift and not from RHEVM.
I didn't see anything related to "cpu steal" in RHEVM, I checked in the UI dashboard and tried to get any related stats from vdsm to see if it reports anything and i couldn't find any.

Can you please point me where should i look or what to search?
Comment 15 Liran Rotenberg 2017-12-26 14:30:52 UTC 
Verified on:
RHV: 4.2.0.2-0.1.el7

OpenShift Master:
v3.7.14
Kubernetes Master:
v1.7.6+a08f5eeb62

Steps of verification:
1. Create OpenShift linked to the RHEV environment.
2. In the OpenShift move to applications and click on the logging kibana.
3. In the kibana click on visualize then create the visualization.
4. In the visualization make the new search to be on the RHEV environment.
5. Add the metrics and buckets to use.

For the verification i have made:
1. Area Chart - (metrics)Y-Axis: Max, collectd.cpu.percent;(Buckets) X-Axis: Data Histogram, timestamp, auto; Split-Area: terms, collectd.type_instance, size 6. Then I clicked on the zoom from the right bar into 'cpu steal'.
2. Pie Chart - (metrics)Slice Size: sum, coolectd.cpu.percent;(Buckets) Split Slices: terms, collectd.type_instance, size 10.

Attaching images.
