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.
NMS Workstation
Monitoring Resource Availability from Multiple Ports and Switches
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.
