Introducing Performance Tuning
Describe performance tuning concepts and methodologies, and interpret different units of measurement to compare metrics.
Gathering Metrics with Performance Monitoring Tools
Investigate performance by using tools included with Red Hat Enterprise Linux to evaluate relevant performance metrics.
Identifying Hardware Resources
Identify system hardware on servers by using and interpreting the output of system utilities.
Configuring Kernel Tunables and System Tuning Daemon Profiles
Configure Red Hat Enterprise Linux for different workload requirements by adjusting tunable kernel settings and by setting a profile for the system tuning daemon.
Managing Resource Limits and Control Groups
Manage resource contention and set limits for resource use with POSIX limits and by assigning services, applications, and user processes to control groups.
Analyzing Performance with Performance Counters and System Call Tracing
Diagnose system and application behaviors by monitoring hardware performance counters and by tracing system calls and library function execution by processes.
Analyzing Performance with SystemTap and eBPF
Diagnose system and application behaviors by using the SystemTap and eBPF tools to trace performance counters and to examine system software events in the kernel and in user processes.
Tuning CPU Usage
Manage CPU resource sharing and scheduling to control CPU usage.
Tuning Memory Usage
Investigate how the Linux kernel manages memory, and tune memory usage for various workloads.
Tuning Storage Device I/O Performance
Evaluate storage I/O performance and use that information to tune performance for different types of storage devices, file systems, and use cases.
Tuning Network Performance
Optimize network throughput, latency, and efficiency.
Tuning Red Hat Enterprise Linux Virtual Machines
Optimize the performance of Red Hat Enterprise Linux virtual machines by tuning profiles and settings to limit virtualization overhead.
Comprehensive Review
Practice skills that you learned in Red Hat Enterprise Linux Performance Tuning. Test the knowledge that you acquired with the Red Hat Enterprise Linux Performance Tuning (RH442) course and prepare for the Red Hat Certified Specialist in Linux Performance Tuning (EX442) exam.
