Thresholds can be set with a view to alert the user by raising a system fault when the set threshold value is crossed. An example would be a system fault raised when the Sensor CPU usage crosses an upper threshold value of say 90%.
Thresholds can be set for CPU usage, Sensor throughput, port throughput, L2 error drop (Layer 2 here refers to too many CRC and Ethernet Packet Compliance errors) and L3/L4 error drop (Layer 3/4 here refers to too many checksum and protocol errors) and memory usage. Thresholds can be set at the root admin domain device list node, child admin domain device list node and the Device_Name node. The threshold page is used to change threshold values for select metrics and optionally generate system faults when those thresholds are exceeded. Thresholds set represent the average values for every minute.
Note
Threshold generated faults for a given device are flushed out on reboot. Settings can be inherited upto two admin domain levels
