Measures reported by NexentaMemTest
By proactively detecting a potential memory contention on the NexentaStor appliance, administrators can easily avert slowdowns or outages of the NexentaStor appliance. The NexentaMemTest test helps administrators in this exercise. This test reports how well the NexentaStor appliance uses the physical memory allocated to it, and leads administrators to abnormal memory usage patterns (if any).
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| totalMemory |
Indicates the total amount of physical memory allocated for the NexentaStor appliance. |
MB |
|
| freeMemory |
Indicates the amount of physical memory that is currently available on the NexentaStor appliance. |
MB |
A high value is desired for this measure. |
| usedMemory |
Indicates the amount of physical memory that is currently used by the NexentaStor appliance. |
MB |
Ideally, the value of this measure should be low. A consistent increase in this value could be a cause for some serious concern, as it indicates a gradual, but steady erosion of valuable memory resources. If this unhealthy trend is not repaired soon, it could severely hamper storage performance. |
| usedPercent |
Indicates the percent usage of physical memory by the NexentaStor appliance. |
Percent |
A low value is desired for this measure. A consistent increase in this value is a sign that physical memory is being over-utilized by the appliance. |
