Part 2

Dashboards

6. Performance-Monitoring Dashboards

What is the overall IaaS performance?

Creating the super metrics

Applying the super metrics

Creating the dashboard

The performance SLA line

Step 1 – create a super metric to define the SLA

Step 2 – create a group for each tier

Step 3 – create policies for each group

Step 4 – map super metrics to policy

Step 5 – add the SLA to each line chart

The resultant dashboard

Alerts

Which VMs are affected?

Adapting the dashboards to different environments

Are you serving my VM well?

Is vMotion causing performance hit?

Is any VM abusing the shared IaaS?

Summary

7. Capacity-Monitoring Dashboards

Utilization information

Rightsizing VMs

Rightsizing large VMs

Rightsizing vCPUs

Step 1 – create a group

Step 2 – create super metrics

Step 3 – create a heatmap
