A systems administrator received a notification that a system is performing slowly. When running the top command, the systems administrator can see the following values: Which of the following commands will the administrator most likely run NEXT?
Based on the output of the top command, which shows a high percentage of CPU time spent on I/O wait (%wa), the command that the administrator would most likely run next is vmstat.
A. vmstat - This command provides a summary of system memory, CPU usage, and I/O statistics. It can be used to identify I/O bottlenecks and other performance issues.
B. strace - This command is used to trace system calls and signals made by a process. It is not directly relevant to identifying I/O bottlenecks.
C. htop - This command is an interactive process viewer that is similar to top but provides more features and capabilities. It may be useful for more detailed analysis of system performance, but is not necessary in this case.
D. lsof - This command lists open files and can be used to identify processes that are holding open file handles. It is not directly relevant to identifying I/O bottlenecks.
A is the answer here, as the I/O wait time is 95%. vmstat will show the resource usage for each process
