How do check the root cause of ISE appliance hung?

[antonioyan99]

Hi Cisco Guru,

One of my client's ISE appliance just got hung this morning.  It was rebooted and is back to operational.

However, the client wants to know the root cause.

Is there a dump file which I can analyze?  The logging doesn't seem to have such info.

Thanks.

"show tech-support" from the cli may shed some light. (Set "term len 0" first and log the output - it will be over 10,000 lines.)

There are also a number of even more detailed logs - they are listed when you run "show tech" that the TAC can analyze if needed.

If the problem recurs they may ask you to turn on some debug level logs to get more supporting information,

Thank you Marvin for the quick response.
