Issue/Introduction

CPU monitor provides very useful data when troubleshooting a Symantec ProxySG or Advanced Secure Gateway (ASG) that is experiencing a high CPU related issue.  
 

Resolution

The CPU monitor can be enabled on the ProxySG or ASG using the web management GUI or using the CLI.

To enable the CPU monitor using the GUI

1. Access the CPU monitor URL at https://x.x.x.x:8082/Diagnostics/CPU_Monitor/statistics.
2. Click the start link to enable CPU monitor.
3. Click the view link to verify that CPU monitor is enabled.  

To enable CPU monitor using the CLI, please perform the following steps

1. Log into the SG via SSH or serial console;
2. Enter the following commands:

#en

#configure terminal

#(config) diagnostics

#(config diagnostics) cpu-monitor enable

      3. Verify that CPU monitor is enabled by entering the show cpu-monitor command.  The output will be similar to:

CPU Monitor:
Configured interval duration:  5 seconds
Current interval complete in:  1 seconds
CPU 0                                               16%
    Miscellaneous                                   13%
    TCPIP                                            1%
    HTTP and FTP                                     1%

NOTE: The CPU monitor should only be enabled when troubleshooting a high CPU issue as it can increase CPU utilization by 2-4% depending on the platform. All other times CPU monitor should be disabled.
