Memory: Kernel Memory in Use

This statistic shows kernel memory that is in use (populated), and can be broken down by kernel cache (kmem cache).

An understanding of operating system internals is required to understand this statistic.

When to Check Kernel Memory in Use

Rarely. If the dashboard were to show kernel memory as a large consumer of available DRAM (in the Usage: Memory section), then this can be used when troubleshooting the cause. Also see Memory: Kernel Memory Allocated, But Not in Use.
