Familiar & understanding with Memory Utilization

Familiar & understanding with I/O Analyses

Familiar & understanding with Network Monitoring

Familiar with various Commands to manage performance issues in Linux Servers

top

vmstat

iostat

free

lsof

tcpdump- Network Packet Analyzer

Following are the Linux performance statistics using sar command.

Collective CPU usage

Individual CPU statistics

Memory used and available

Swap space used and available

Overall I/O activities of the system

Individual device I/O activities

Run queue and load average data

Network statistics

Report sar data from a specific time

Process Management

Understanding ps commands with custom properties & Nice values etc

Different stats of a process like "D", "S", "T", "Z" etc

Kill commands to terminate the process

Lab

Linux Find Commands

Basic find commands for finding files with names

Find files based on their permissions

Search files based on owners & groups

Find files and directories based on date & time

Find files and directories based on size

Top Running Processes

Command to list out top processes consuming highest memory utilization

Command to list out top processes consuming highest cpu utilization

Lab on lsof - List open files & fuser

lsof command used in many Linux/Unix like system that is used to display list of all the open files and the processes.

Lab on tcpdump- Network Packet Analyzer

For example: number of packets received (transmitted) through the network card, statistics of packet failure etc

Practice Lab Sessions
