I’ve never been asked to provide one of these logs, yet there are over 400 of them in my VIQ dating back to 2018. It sounds looks like this could be a valuable source of information regarding devices rebooting or failing (following up on system core dump alarms etc).
Documentation states that this is off by default, but I can’t find the “Device Data Collection” mentioned in the documentation to check my settings (https://docs.aerohive.com/330000/docs/help/english/ng/Content/gui/administration/downloading-kddr-logs.htm?Highlight=kddr)
This previous thread was never answered. https://community.extremenetworks.com/hivemanager-platform-233172/is-there-better-documentation-for-extreme-cloud-iq-about-kddr-logs-the-link-i-have-is-for-hive-manager-7828368

Sorry, just realizing I never answered your first question- What are KDDR logs for? These are Kernel Diagnostic Data Recorder (KDDR) logs, and they are basically troubleshooting logs that record failures or interruptions within ongoing processes. These are more advanced troubleshooting logs that would need to be interpreted by our engineers, at least partly because the logs come out in binary content. Typically we ask for KDDR logs when we are experiencing unexplained reboots or crashes.
