To find out which processes are using swap space in Linux, you can use the “top” or “pmap” command.
- “top” command:
The “top” command provides an interactive display of system information, including a list of processes and their associated resource usage. You can use the “top” command to see the amount of swap space being used by each process. To display this information, run the following command:
top
In the output, the “SWAP” column shows the amount of swap space being used by each process.
- “pmap” command:
The “pmap” command provides a detailed view of the memory usage of a process, including its use of swap space. To see the amount of swap space used by a particular process, run the following command:
pmap pid
Replace “pid” with the process ID of the process you want to inspect. The “pmap” command will display information about the process’s memory usage, including the amount of swap space being used.
Both the “top” and “pmap” commands are useful tools for monitoring and understanding the use of swap space on a Linux system. By using these commands, you can identify processes that are using excessive swap space, and take appropriate action to optimize system performance.
