Memory Page Swapping

The memory page swapping graph shows how frequently the system must page to disk, in kilobytes per second.

The system is designed to swap memory regularly, so some memory swapping is expected and is not an indication of problems with your appliance. Unless the system consistently swaps memory in high volumes, memory swapping is normal and expected behavior (especially on C170appliances). To improve performance, you may need to add Email Security appliances to your network or tune your configuration to ensure maximum throughput.

Note

This graph also indicates a threshold for memory page swapping that is a visual reference only. To adjust the position of this line, see Adjusting the Reference Threshold in System Health Graphs for Email Security Appliances. You can configure your Email Security appliances to send you alerts that will suggest actions that you can take to address capacity issues.
