Measurement Unit |
Interpretation |
| Total_memory |
Indicates the total amount of memory allocated for the security server. |
MB |
|
| Used_memory |
Indicates the amount of memory that is currently utilized by the security server. |
MB |
A value close to the Total_memory measure indicates that the memory resources are depleting rapidly. |
| Free_memory |
Indicates the amount of memory that is currently available for use in the security server. |
MB |
A sudden decrease in this value could indicate an unexpected/sporadic spike in the memory utilization of the security server. A consistent decrease however could indicate a gradual, yet steady erosion of memory resources, and is hence a cause for concern. |
| Memory_utilization |
Indicates the percentage of memory that is utilized by the security server. |
Percentage |
If the value of this measure is close to 100%, it indicates that the memory utlization of the appliance is at its peak. Therefore, the administrator may need to allocate additional memory resources to the security server. |
