Linux virtual memory management (VMM) has often been a mystery to sysadmins and developers. Most either ignore the various kernel tunables or set vm.swappiness = 1 and then panic if anything ever shows up in swap. But there has been an overhaul of the VMM subsystem, and customers can now see systems with low swappiness and large amounts of memory (256G+), slowly grow their swap usage to 100%, and remain stable and performant. The old methods for monitoring memory usage need to change to reflect this, and you need to understand why and how. Plus, learn how to harness the capabilities of modern Linux systems to keep users from accidentally using too much memory.
This webinar will teach:
- What has changed in kernel virtual memory management.
- Why this is important for your workloads.
- How you should change your system monitoring in response.
- How to make use of cgroups v2 to avoid some common memory issues.
