How can I generate a Red, Amber, Green (RAG) status for last months CPU of all my VMs in a cluster?

The Reports accordion has a number of highly configurable reports that allow the user to view and present their data in various ways. One of the more common reporting use cases is to generate a RAG status for a selection of Virtual Machines. To do this, follow these instructions:

• Go to the reporting accordion
• Select the Metric Analysis Multi Chart
• Select the baseline to be used for the report. This is normally set to be the default baseline, which is a summary of the previous 3 months of data.
• For the Level 1 Entity Type drop down, select ‘Cluster’
• For Grouping Filter 1 drop down, select ‘Select Clusters from list’
• For Grouping Value 1 drop down, select the Cluster in question.
• For the Level 2 Entity Type drop down, select ‘VM’
• For Grouping Filter 2 drop down, select ‘Select all VMs’

You have now filtered this to report to be run for all VMs in a chosen cluster.

This report allows for up to 3 metrics to be presented. Let’s configure it to use both CPU and Memory.

• For Metric drop down, select both ‘CPU Utilisation Server Level (%)’ and ‘Memory Utilisation MB (%)’
• Red Operator allows you to select the RAG condition, in this drop down, leave as default
• Set the threshold to be 80
• Amber Operator, leave as default
• Set the threshold to be 60
• For summary level, select ‘daily summary’
• Select ‘Specific date range’ - this will run the report over all data covered by the baseline duration
• In chart type, select box plot. This will speed up the report.
• For percentile value, use the default 95th percentile
• Leave all other entries as default

At this point, we have configured a report to show daily summaries of all VMs in a chosen cluster. Any cluster where 95th percentile of either CPU or Memory for any day goes above 80% will be highlighted as red. If above 60, it will be amber.
