In order to obtain a full core dump for analysis when the Edge Secure Web Gateway (ProxySG) appliance restarts, you have to change the 'Core Images' settings to 'Full'. Or else, by default, the 'Full core' will not be written during the restart.


You can do the following to change the Core Images settings to 'Full' either through Management Console or CLI:

In the Management Console:

  1. Log in to the Management Console (https://<IP_address>:8082/ ).
  2. Select Maintenance  > Core Images > Core Images.
  3.  For the core image type, select Full.
  4. Click Apply to save your changes.

In the CLI:

  1. Log in to the CLI via SSH or the serial console.
  2. Type the following commands:
#conf t
#(config)restart core-image full
After you change the above settings:
A. Whenever the Proxy encounters an unexpected reboot/restart, it will write a Full Core automatically (you do not have to manually force the core, just collect the existing Core for analysis).
B. If there is a hang, or if there is a need to investigate the Proxy unexpected behavior or if Proxy is in a bad state, we may need to force a 'Full' core dump for further analysis.
  1. To force a core dump, you will have to restart the Edge SWG. Restarting the Edge SWG via GUI will not generate the core dump. You will to restart via CLI.
  2. Once you have logged into the CLI via SSH or serial console, use the following commands
#restart abrupt

IMPORTANT: When the full core dump is enabled, the appliance takes a longer time to reboot as it need time to generate/write the core dump. The duration of reboot depends on how much memory the unit has and how much of it was in use at the time of the restart. It usually takes 10 to 20 minutes to generate a full core dump.


Also You can Validate from Sysinfo Provided by Customer, If "Full-Core" is Enabled or not, Look for Below Config in Sysinfo

!- BEGIN general
restart core-image full  <------- This indicates full core is Enabled, If you do not see that indicates full core is disabled.
restart mode hardware
!- END general
