Description of problem (please be detailed as possible and provide log
snippests):
 In multiStorageCluster , metrics values like "Raw Capacity,Used capacity,IOPS	,Throughput,Latency"  are showing as zero for external storagesystem. 
for internal storagesystem we can see the values. 

if we create ODF with only external storagesystem we can see the values. 
when we create ODF with internal storagesystem and add external storagesystem then values are shown correctly only for internal storagesystem not external one. attached screenshot for reference.

Does this issue impact your ability to continue to work with the product
(please explain in detail what is the user impact)?


Is there any workaround available to the best of your knowledge?


Rate from 1 - 5 the complexity of the scenario you performed that caused this
bug (1 - very simple, 5 - very complex)?


Can this issue reproducible?
Yes

Can this issue reproduce from the UI?
Yes

If this is a regression, please provide more details to justify this:


Steps to Reproduce:
1. Install OCP cluster
2. Install ODF.
3. Create internal storagesystem
4. Create external storagesystem
5. In the UI, Navigate to Data Foundation and Storage Systems, we can see both the storagesystems but metrics are shown zero for external storage system.

Actual results:
In the UI, Navigate to Data Foundation and Storage Systems, we can see both the storagesystems but metrics are shown zero for external storage system. for internal storagesystem the metrics are shown correctly.

Expected results:
In the UI, Navigate to Data Foundation and Storage Systems, we can see both the storagesystems metrics should be shown correctly for external storage system as well.
