Report generation takes approximately 25 seconds when analyzing 90 days of data.

The dashboard provides overall information about your cluster and has six tiles.

Click New Report to generate the report. Select a History (Date Range). Before the initial report generation, the default is a seven day history. Click Run; Running replaces Run and a countdown is displayed until Unravel starts collecting the data. A dark green bar banner is briefly displayed noting the report has started. New Report pulsates blue until the report is completed.

If the report has been generated New Report remains blue, a light green bar notes the success, and the page is populated with the new data. If the report generation was unsuccessful, a red bar containing an error message is displayed. The New Report button becomes orange and remains so until a report is successfully generated. The tab continues to show the last successfully generated report. All successful reports are archived. Click Download JSON to download the report.

This tile contains information about your cluster, including the hosts. The Host Summary section shows the cluster's capacity across all hosts.

To see each host's hardware specifications and the host's roles click . The table can be searched on hostname. The potential roles are:

The donut graphs display the top 10 for each category. This example has three app types, four users, and six queues over the period analyzed.

The first two graphs display the cluster's CPU and memory utilization over the time period. The average usage is listed on the right-hand side of the title bar. Hover over the parenthetical text next to the resource's name to see Unravel's analysis of your cluster's usage for that resource. Here, the CPU and Memory are both "Very under-utilized and over-provisioned".

The heat-map is a map of the CPU/Memory usage and capacity by a weekday and hour, e.g., Monday between 5 and 6 a.m. Each time slot is color coded to show how relatively hot the time slot is relative to the rest of the map. You can quickly see the load distribution across your cluster.age. You can filter the heatmap by CPU or memory. It opens displaying CPU. The CPU graph above noted the CPU is under-utilized and the heatmap graphically supports that analysis.

Report generation takes approximately 20 seconds.

Generating reports

Click New Report. If you have previously generated a report, the modal opens with your prior settings.

You must select:

1. Cloud Product/Service:

   • Google Compute Engine (IaaS)

   • Google DataProc

   • Amazon EC2 (Iaas)

   • Amazon EMR

   • Azure (Iaas)

   • Azure HDInsight

2. Region: The available regions are specific to the Cloud Product/Service selected.

3. Storage Type: You can choose Local Storage or Object Storage. The Storage Name is determined by the storage type chosen.

4. One or more VM types: The list is populated based upon the Cloud Product/Service and Region you chose.

To select a subset of VM types, check the box for each VM Type. To select all types check the box in the header. Unravel maps each host to the best fit of the VM types you selected. Click Reset to clear your selections.

Unravel uses publicly listed prices. You can enter a custom cost for a VM type for Unravel to use for the cost calculation for that VM type.

Once you have made your selections you can either run or schedule your report.

Click Run to immediately generate the report. The pop-up is greyed out and then closed once Unravel starts to generate the report. If Unravel can generate the report a dark green banner is briefly displayed at the top of the window noting the report has started; if the report can't be started a dark red banner appears with an error message.

New Report pulsates blue until the report is completed. If the report is successful a light green bar appears and New Report remains blue. If Unravel couldn't generate the report, New Report becomes orange and light red bar noting the error is displayed. (Note: the button remains orange until a report is successfully generated.)

To schedule the report, click Schedule. Click Download JSON to download the displayed report in the JSON.

Unravel generates reports using:

• Lift and Shift: a one-to-one mapping of each on-prem host on the cloud based on your host's capacity.

• Cost Reduction: a one-to-one mapping of each on-prem host on the cloud based on your host's actual usage.

Report Layout

By default, the tab opens displaying the last report generated for Lift and Shift. Click Cost Reduction to see that report. Each host is mapped to one of the instances you selected when generating the report.

Immediately below the method tab is a brief explanation of the method along with the Cloud Product/Service used for the report.

A summary for the Total Hourly Cost, Total Object Storage Required (or Local Storage), and instance your hosts are mapped to. Immediately below a table lists the mapping for each host to a VM type.

The table contains:

• Host: Your on-prem host.

• Host Role: Shows the host role, server, worker, or client. A host can have more than one role. This column is only available in Unravel 4.5.3.0 or later.

• Actual Usage: The host's actual resource usage.

• Capacity: The total capacity of the host.

• Recommendation: The cloud instance Unravel maps your host to.

• Total Cost ($/Hour): The hourly cost of the instance.

Lift and Shift

This method is a one-to-one mapping of each on your on-prem host's capacity to an equivalent VM type in the cloud (the mapping meets or exceeds, where necessary, your host's capacity). In this case, the on-prem host is under-utilized. Since Unravel is matching capacity, the mapped instance is also underutilized with a Total Hourly Cost of 2.211.

Cost Reduction

This method maps each host to an instance based on the host's actual usage not its capacity. This report maps the same host used in the Lift and Shift report. The Total Hourly Cost is $1.147, a saving of $1.064.

Comparison of lift and shift to cost reduction

Both Lift and Shift and Cost Reduction perform a one-to-one mapping, but Cost Reduction typically is less expensive since it maps host to a VM based upon the host's actual usage.

Report generation takes approximately 20 seconds. This report is only available in 4.5.3.0 and later.

The report is a matrix mapping on-prem platforms to the service which are available and compatible on a cloud provider. To generate a report select New Report. Select the Cloud Product (Google DataProc, Amazon EMR, Azure HDInsight) you want to use for the report for.
