In this section you will learn how VirtualMetric calculates the recommendation under analysis.
The CPU recommendation report shows the CPU usage of devices and the recommendations provided.
| Metric Name | Calculation | Statistical Operation |
|---|---|---|
CPU Limit (MHz) | Max Clock Speed * Processor Count * CPU Maximum / 100 | MAX |
CPU Usage (MHz) | (Max Clock Speed * Processor Count * CPU Maximum / 100) * Cpu Usage MHZ Percent/100 | AVG |
Recommended (MHz) | 1.0 / 0.6 * Avg CPU Usage | |
Reclaimed (MHz) | Max CPU Limit - Recommended Limit MHz | |
Recommendation | ◆ If Max CPU Limit - Recommended = 0 No Change ◆ If Max CPU Limit > Recommended Decrease ◆ If Max CPU Limit < Recommended Increase |
| Metric Name | Calculation | Statistical Operation |
|---|---|---|
CPU Limit (MHz) | Max Clock Speed * Processor Count | MAX |
CPU Usage (MHz) | Average of Cpu Usage | AVG |
Recommended (MHz) | 1.0 / 0.6 * Avg CPU Usage | |
Reclaimed (MHz) | Max CPU Limit - Recommended Limit MHz | |
Recommendation | ◆ If Max CPU Limit - Recommended = 0, No Change ◆ If Max CPU Limit > Recommended, Decrease ◆ If Max CPU Limit < Recommended, Increase |
The memory recommendation report shows the memory usage of devices and the recommendations provided.
| Metric Name | Calculation | Statistical Operation |
|---|---|---|
Current Memory | Memory Capacity | AVG |
Memory Usage | Memory Usage | AVG |
Recommended (MB) | 1.0 / 0.6 * Avg CPU Usage | |
Reclaimed (MB) | Memory Capacity - Recommended Limit | |
Recommendation | ◆ If Memory Capacity - Recommended Limit = 0, No Change ◆ If Memory Capacity > Recommended Limit, Decrease ◆ If Memory Capacity < Recommended Limit, Increase |
The power-off report shows inactive devices and how long they have been offline.
| Metric Name | Calculation | Statistical Operation |
|---|---|---|
Duration | Current Date - Power Off Since | |
Powered Off Since | Epoch | ◆ When counter value returns 0, MAX ◆ When counter value returns 1, MIN |
Used Disk (MB) | Storage Used | MAX |
Provisioned Disk (MB) | Total Storage | MAX |
All of the powered off reports have one common condition: State = 'Off' and Record Status > 0 and Since off > 0
This report displays the idle machines in the environment. VirtualMetric checks the data from the last 14 days, and, if the ratio of hosts on a machine with
an average CPU use below 100 MHz -or-
an average IO use below 20 KB/s -or-
an average network use below 1 KB/s
is greater than 90%, then it flags that machine as idle on the report.
| Metric Name | Calculation | Statistical Operation |
|---|---|---|
Duration | Current Date - Date of Idle | |
Current CPU | Avg CPU | AVG |
Memory Used | Storage Used | MAX |
Memory Capacity | Total Storage | MAX |
Used Disk (MB) | Consumed Memory | MAX |
Disk Capacity (MB) | Total Memory | MAX |
All idle reports have one common condition: State = 'Running' and RecordStatus > 0
