Measures reported by ARSWMemUsageTest

The Arista Switch offers true innovation for high performance data center switches delivering support for a programmable forwarding pipeline, flexible profiles, up to 6.4Tbps of forwarding with 24MB of dynamic packet buffer and a choice of interface types in a set of power efficient compact systems. This switch also offers high density, non-blocking ethernet ports that are controlled through an extensible modular Linux based network operating system. Arista switches are designed for high availability and provide various hardware and software-based availability features that help prevent loss of data flow in the unlikely event of subsystem failure.

Often, in environments where Arista Switch is deployed, unavailability and poor performance of the switch can adversely impact inter-device communication. If not detected and resolved quickly, such issues can snowball and degrade performance of mission-critical applications in the target environment. This may directly impact the reputation and business revenue of the environment. To avoid such adversities, it is important to monitor the operations of the Arista switch continuously.

This test monitors the memory utilization of the Arista Switch and proactively alerts administrators to potential memory contention, if any.

Outputs of the test : One set of results for the target Arista Switch that is to be monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Total_memory Indicates the total amount of memory allocated to the target switch. GB  
Used_memory Indicates the amount of memory that was already utilized by the switch. GB 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. GB A sudden decrease in this value could indicate an unexpected/sporadic spike in the memory utilization of the switch. A consistent decrease however could indicate a gradual, yet steady erosion of memory resources, and is hence a cause for concern.
Buffer_memory Indicates the total amount of real or virtual memory allocated for use as memory buffers. GB  
Memory_usage Indicates the percentage of memory currently utilized by switch. Percent A value close to 100% indicates abnormal memory consumption by switch.
