Chapter 3. Viewing resource optimization reports
Historical data reports are available to help you assess your level of optimization over time, in order to make informed decisions about your future public cloud investment.
3.1. Viewing historical utilization data
The resource optimization service enables you to see how your system utilization scores have been trending over the last 7-45 days. The service displays a bar chart that indicates CPU Utilization and Memory Utilization percentages on a daily basis.
Complete the following steps to view, filter, and sort system historical utilization data:
Procedure
- Navigate to the Business > Resource Optimization page. The system states screen opens.
- Click on the Name header on the left side of the page to filter by Name, State or Operating system. Use the sort arrow to the right of each column name to sort by OS, CPU, Memory Utilization, I/O Output, Suggestions, State, and Last Reported. Clicking once sorts the column so that optimized systems are displayed first. Clicking a second time sorts the column so that systems categorized as Waiting for data are displayed first.
- Systems that have been analyzed render in blue. Click on the blue system name for a more detailed view.
- Click on the Actions dropdown to see the system’s properties in Inventory, such as operating system, infrastructure, configuration, BIOS and other data.
- By default, the resource optimization system displays 7 days of utilization results. Click on the dropdown labeled Last 7 Days to view 45 days of utilization data. To view specific days and the utilization scores for those days, use the mouse wheel and buttons to pan and zoom across the bar chart.
- Scroll down to see specific suggestions for that system.
3.2. Downloading resource optimization service reports
You can download the resource optimization reports for all registered systems. The report identifies the following data gathered over the last 7- 45 days:
- Registered systems. This section details the number of systems that are optimal, non-optimal, and stale. The optimized state is determined by examining CPU, RAM, and disk I/O usage, combined with CPU idle time, over a period of 24 hours. If the calculation, based on the examination of the three factors, results in a middle point, the resource optimization service labels the system as optimized. A stale system is defined as one that has not submitted data to the resource optimization service in 7 days.
- Kernel pressure stall information (PSI). This is an analysis of the number of systems that have PSI enabled and the number of systems that have NOT enabled PSI. PSI allows you to receive better system recommendations since it can identify resource pressure increases as they develop.
- System performance issues. Specific performance issues such as RAM or CPU related peaks are identified along with the number of occurrences.
- Most used current instance types. The service will evaluate and display your top 5 most frequently used instance types across all registered systems.
- Suggested instance types. The service identifies the top 5 frequently suggested instance types based on the most recent utilization metrics. This may indicate that a change is necessary for better resource allocation.
- Suggested instance types in 45 days. This metric displays the top 5 frequently suggested instance types based on 45 days of historical data. You can also view the effectiveness of changes you have made in the recent past.
Prerequisites
The following prerequisites and conditions must be met to create a PDF of the executive report:
- The Insights client is installed on the system and is operational.
- Performance Co-Pilot is installed and correctly configured.
- At least one system is registered and sending data to the resource optimization.
The longer your systems have been sending information to the resource optimization, the more accurate and valuable the recommendations will be.
Procedure
- Navigate to Business > Resource Optimization.
- In the top right corner, click on Download executive report.
- You will see a dialog box with the message, Export successful and notice the PDF file in your taskbar.
