Installing And Monitoring Linux Services E-Learning
Virtual training for installing and monitoring Linux services provides the following:
- Monitor and adjust Linux performance
- Introduction to performance monitoring in Linux
- Four important subsystems to control:
I / O
Familiarity with CPU usage
Such as field switches, executable queue, CPU usage and average load
Familiarity and understanding using memory
Familiarity and understanding with input / output analysis
Familiarity and understanding with network monitoring
tcpdump Network Packet Analyzer
- Below are the Linux performance statistics using the sar command:
Collective use of the processor
Individual CPU statistics
Memory used and available
Replace used and available space
General system input and output activities
Individual device I / O activities
Load the queue and load medium data
Report sar data from a specific time
- Process management:
Understand ps commands with custom properties and beautiful values and so on
Various process statistics such as “D”, “S”, “T”, “Z” and so on
- Find commands in Linux:
Find files based on their permissions
Search for files by owners and groups
Find files and directories by date and time
Find files and directories by size
- Top running processes:
Command to list the top processes that use the most memory
Command to list the top processes with the highest CPU usage
Lab on lsof
- List of open files and fuses:
The lsof command is used in many systems such as Linux / Unix to display a list of all open files and processes.
Lab in tcpdump
- Network packet analyzer:
For example: number of packets received (transferred) via network card, packet failure statistics, etc.
- Practice lab sessions:
Practical Lab Session – High CPU Usage
Practical lab session – high memory usage
The student learns in this course:
- Familiarity with monitoring tools that can be used to investigate performance issues on a Linux server.
- Familiar with the four subsystems that need to be monitored. Processor / Memory / IO / Network
- Created many labs to illustrate performance issues with examples.
- Understand the use of high memory in a Linux server that causes performance problems.
- Perception of high CPU usage on a Linux server that causes performance issues.
- Understanding network usage (packet loss, errors) in Linux Server causes performance problems.
- Understand the use of High IO disk in Linux server that causes performance problems.
- Familiar with tcpdump – Network packet analyzer
- Familiar with lsof – List open files
Linux + finds commands using various examples
- Command to list the top processes that use the most memory
- Command to list the top processes with the highest CPU usage
This course is useful for the following groups:
Anyone who wants to gain knowledge and understanding of performance monitoring and tuning in Linux management can take this course.
