Red Hat Performance Tuning: Linux in Physical, Virtual, and Cloud - Red Hat Learning Subscription (RH442LS)
Diagnose and remove performance bottlenecks on Red Hat Enterprise Linux, wherever it runs.
About this course
Diagnose and remove performance bottlenecks on Red Hat Enterprise Linux, wherever it runs. You will gather metrics and benchmarks, trace and profile system activity, apply tuned profiles and kernel tunables, set resource limits with control groups, and tune CPU, memory, storage, file system and network use on physical hosts, virtual guests and cloud instances.
What you'll learn
- Analyze and tune for resource-specific scenarios
- Applying tuning profiles with the tuned tool
- Tune in virtual environments (hosts and guests)
- Trace and profile system events and activities
- Tune resource limits and utilization using systemd-integrated cgroups
- Gather performance metrics and benchmarking data
Curriculum
- Describe performance tuning concepts and goals.
- Evaluate the large selection of performance monitoring tools that are included with Red Hat Enterprise Linux.
- View and interpret hardware resource listings.
- Configure the operating system to tune for different workload requirements.
- Manage resource contention and set limits for resource use on services, applications, and users using cgroup configuration.
- Diagnose system and application behaviors using a variety of resource-specific tracing tools.
- Manage CPU resource sharing and scheduling to control utilization.
- Manage settings for efficient memory utilization for different types of workloads.
- Manage settings for efficient disk utilization in various use cases.
- Manage application efficiency for file system utilization.
- Manage application efficiency for network utilization.
- Distinguish the requirements for tuning in virtualized environments.
- Demonstrate skills learned in this course by observing system performance using the appropriate tools, evaluating system metrics, and configuring settings to improve performance.
Who it's for
RHCE-level administrators who need to get more performance from critical systems.
