Monthly Meeting - CGroups v2

Our monthly technical meeting

Control Groups (CGroups) provides methods for hierarchically managing resources within the system such as memory consumption, CPU time, block device bandwidth in read and write operations, etc. CGroups provides a great deal of useful features when the resource in question is shared across multiple workloads within the same system (such as backups being written to the same storage device as a production database or CPUs in any mixed workload).

Within the RHEL family, RHEL 6 introduced CGroups (now known as CGroups V1). Over time, the Linux community began CGroups V2 in an effort to improve upon the work accomplished by CGroups V1 and introduce a far more simple hierarchy and easier-to-use subsystem for managing resources hierarchically. RHEL 8 introduces CGroups V2.

Join Marc "unclemarc" Richter as he walks us through the major changes to CGroups V2 and how that might change how you deploy and use control groups in your organization. As usual, Marc will have a live demonstration which is sure to thrill audience members, both young and old.

• Lightning talk: tracer - Do I need to reboot? - Patrick Ladd

If you'd like to sign up to do a lightning talk (5-10 minutes on any technical topic) please contact me.

After the meeting we'll adjourn to a local watering hole for adult beverages and a bite to eat.
