Monitoring Switch Health

To monitor resource availability, the NMS (Network Management System) needs to collect significant 
amounts of data from each switch. As the number of ports per switch (and the number of switches) 
increases, the volume of data can become overwhelming. The Health Monitoring feature can identify and 
monitor a switch’s resource utilization levels and thresholds, improving efficiency in data collection.

Health Monitoring provides the following data to the NMS:

• Switch-level Input/Output, Memory and CPU Utilization Levels

• Module-level and Port-level Input/Output Utilization Levels

For each monitored resource, the following variables are defined:

• Most recent utilization level (percentage)

• Average utilization level over the last minute (percentage)

• Average utilization level over the last hour (percentage)

• Maximum utilization level over the last hour (percentage)

• Threshold level

Additionally, Health Monitoring provides the capacity to specify thresholds for the resource utilization 
levels it monitors and generates traps based on the specified threshold criteria.
