System requirements

Splunk Enterprise supports workload management on Linux operating systems only.

Linux kernel

Splunk Enterprise version 9.0 and higher requires Linux kernel version 3.x or higher. For more information on supported Linux kernel versions for Splunk Enterprise, see Supported operating systems in the Installation Manual.

Supported Linux distributions

Splunk Enterprise version 9.0 and higher supports workload management on these Linux distributions:

• RHEL 7, 8, and 9
• CentOS 7, and 8
• Ubuntu 16.04 LTS and higher
• SUSE 12 and 15

Supported cgroups version

Workload management supports Linux cgroups v1 only.

Workload management does not currently support Linux cgroups v2. If your Linux system has been upgraded to a version running cgroups v2, you must revert your system to cgroups v1 to use Workload Management in Splunk Enterprise. For additional guidance and resources, see Workload Management operation during the transition to cgroups v2.

Before you can configure and enable workload management in Splunk Enterprise, you must set up the underlying Linux operating system to allow splunkd to manage cgroups. See Set up Linux for workload management.

Systemd version

Workload management requires systemd version 219 or higher.

Systemd is not a mandatory requirement, but if systemd is running on your Linux instance, it must be version 219 or higher.
