1Overview

With System Monitor function, you can:

Monitor the CPU utilization of the switch.

Monitor the memory utilization of the switch.

The CPU utilization should be always under 80%, and excessive use may result in switch malfunctions. For example, the switch fails to respond to management requests (ICMP ping, SNMP timeouts, slow Telnet or SSH sessions). You can monitor the system to verify a CPU utilization problem.

2Monitoring the CPU

2.1Using the GUI

Choose the menu MAINTENANCE > System Monitor > CPU Monitor to load the following page.

Figure 2-1 Monitoring the CPU

Click Monitor to enable the switch to monitor and display its CPU utilization rate every five seconds.

2.2Using the CLI

On privileged EXEC mode or any other configuration mode, you can use the following command to view the CPU utilization:

show cpu-utilization View the memory utilization of the switch in the last 5 seconds, 1minute and 5minutes.

The following example shows how to monitor the CPU:

Switch#show cpu-utilization

Unit CPU Utilization

No. | Five-Seconds One-Minute Five-Minutes

3Monitoring the Memory

3.1Using the GUI

Choose the menu MAINTENANCE > System Monitor > Memory Monitor to load the following page.

Figure 3-1 Monitoing the Memory

Click Monitor to enable the switch to monitor and display its memory utilization rate every five seconds.

3.2Using the CLI

On privileged EXEC mode or any other configuration mode, you can use the following command to view the memory utilization:

show memory-utilization View the current memory utilization of the switch

The following example shows how to monitor the memory:

Switch#show memory-utilization

Unit | Current Memory Utilization
