vCloud Usage Meter - Introduction

As we mentioned in VSPP section, vCloud Usage Meter (UM) is the product used to monitor, measure, and report monthly points usage to Aggregator. Let's examine it.

Information collected on an hourly basis includes:

• Time at which data is collected

• Host DNS name
• Host RAM (physical memory)
• vSphere license type
• Virtual machine vCenter name
• Virtual machine hostname
• vRAM (allocated virtual memory)
• Billing vRAM (calculation based on reserved virtual memory and per-virtual-machine memory cap)

• Virtual machine CPU (count of virtual CPUs)
• Virtual machine Instance UUID (universal unique identifier)

• Virtual machine location in vSphere Inventory

Data collected is stored in the PostgreSQL database of the virtual appliance itself.

Deploying UM

1. Download UM OVA Template (by the time of this post UM v3.0.2 was the latest released from the following link http://www.vmware.com/download/download.do?downloadGroup=UMSV3) 
2. Deploy OVA Template using vCenter or Host (while deployment, you need to configure VA network settings) 
3. From the console, login to CLI using default username/password (root/vmware). Change the root password using passwd command.

4. Assuming network settings weren't properly configured during OVA deployment, you can run the following script from console to reconfigure network settings (/opt/vmware/share/vami/vami_config_net)

5. Next you need to configure Service Provider WebUI password. For this, run the following script /opt/vmware/cloudusagemetering/scripts/webpass. 
6. Change the hostname to user friendly one using the script /opt/vmware/share/vami/vami_set_hostname <NAME>.

7. Configure your time settings from UM console

8. After configuring hostname and time settings, you need to restart tomcat service as follow service tomcat restart for changes to reflect.

Once all above steps are completed, login to UM WEBUI using the URL https://<um-ip>:8443/um
