In the first part for this series we’ve installed and configured vCloud adapter for vC Ops.
The OvDC Admin Custom Dashboard includes many elements related to one another which are mostly rely on Super Metrics. In this post we will create the Virtual Machine related Super Metrics.
Super Metrics
As I mentioned in my previous post, OOTB the vCloud adapter will not show performance metrics for vCloud resource kinds, it will only show the logical structure.
PvDC > OvDC > vApp > VM > Datastore
For that reason, I will be using vC Ops 5.8.1 in order to create quite a few Super Metrics, starting with Virtual Machines related ones.
VM Configured Memory in GB
sum(This Resource: Memory|Guest Configured Memory (KB))/1048576
| Memory|Guest Configured Memory (KB) = Resource Kinds > Virtual Machine > Attribute Kinds: Memory > Guest Configured Memory (KB) |
Note: before double clicking the metric attribute kind, click on the THIS button first
VM Snapshot Used Space (%)
(sum(This Resource: Disk Space|Snapshot Space (GB))/sum(This Resource: Disk Space|Virtual machine used (GB)))*100
| Disk Space|Snapshot Space (GB) = Resource Kinds > Virtual Machine > Attribute Kinds: Disk Space > Snapshot Space (GB) |
| Disk Space|Virtual machine used (GB) = Resource Kinds > Virtual Machine > Attribute Kinds: Disk Space > Virtual machine used (GB) |
Note: before double clicking the metric attribute kind, click on the THIS button first
The next two SM will use to show how much vCPU and vMemory is recommended for each VM in the OvDC based on how much resources are being wasted.
I used +1 basis in my calculations based on the fact that potentially vC Ops can recommend removing all vCPU/vMem for an idle VM. This doesn’t make a lot of sense so I did some manipulation to provide the minimum recommended number.
VM Recommended vCPU Based on +1 vCPU
(sum(This Resource: CPU Usage|Provisioned CPU Cores)-sum(This Resource: Waste|vCPU|Total))+1
| CPU Usage|Provisioned CPU Cores = Resource Kinds > Virtual Machine > Attribute Kinds: CPU > Provisioned CPU Cores |
| Waste|vCPU|Total = Resource Kinds > Virtual Machine > Attribute Kinds: Waste > vCPU > Total |
Note: before double clicking the metric attribute kind, click on the THIS button first
VM Recommended vMem Based on +1GB
((sum(This Resource: Memory|Guest Configured Memory (KB))-sum(This Resource: Waste|Memory|Total))/1048576)+1
| Memory|Guest Configured Memory (KB) = Resource Kinds > Virtual Machine > Attribute Kinds: Memory > Guest Configured Memory (KB) |
| Waste|MemoryTotal = Resource Kinds > Virtual Machine > Attribute Kinds: Waste > Memory > Total |

In the next part for this series, we will be focusing on creating PvDC, OvDC and vApp level Super Metrics, stay tuned!
