ISE troubleshooting with CLI and log files

[nolanrumble]

Hi All,

I'm looking for some assistance please. I'm struggling to find a table which details what each log file's purpose is on the CLI. For example:

What log files must I look at to troubleshoot active directory issues?

What log files must I look at to troubleshoot replication issues across the ISE deployment?

What log files must I look at to troubleshoot patch upgrade status on a particular node?

I'm looking for something like this:

Log file name	Function/purpose
replication.log	All replication status/updates that happen throughout the ISE deployment and any errors that might occur.

This information would need to cover both system and application based logs.

Can someone point me in the right direction please?

Thanks!

Nolan

If your customers are experiencing these issues, it's best to open TAC cases. The reports, live logs, and log sessions are what for customers whereas the debug logs are mainly for TAC, etc. If customers preferring to troubleshoot themselves, then the debug log file names imply the areas they are for. Often, we would need to cross reference multiple debug log files from different nodes so TAC assistance is preferred.
