Linux operating system requirements

Workload management for Splunk Enterprise is supported on Linux operating systems only.

Linux kernel

Workload management requires Linux kernel version 2.6.25 or higher. For information on currently supported and deprecated Linux kernel versions for Splunk Enterprise, see Supported operating systems in the Installation Manual.

Supported Linux distributions

Splunk Enterprise supports workload management on these Linux distributions:

• RHEL 6, 7, 8, and 9
• CentOS 6, 7, and 8
• Ubuntu 16.04 LTS and higher
• SUSE 11 and 12

Supported cgroups version

Workload management supports Linux cgroups v1 only.

Workload management is not compatible with Linux cgroups v2. If your Linux system has been upgraded to a version that runs cgroups v2 by default, you must revert your system to cgroups v1 to use Workload Management in Splunk Enterprise.

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.
