How can I tell which process is using my memory?
You can check memory of a process or a set of processes in human readable format (in KB or kilobytes) with pmap command. All you need is the PID of the processes you want to check memory usage of. As you can see, the total memory used by the process 917 is 516104 KB or kilobytes.

How do I find the top 10 memory consuming process in Linux?
The Linux ‘top’ command is the best and widely used command that everyone uses to monitor Linux system performance. It displays a real-time view of the system processes running on the interactive interface. You should run the top command in batch mode to find out top memory consuming processes in Linux.
What is top command used for in Unix?
The Unix top command is a very useful way to see what programs are currently running on the system and how heavily they are using system resources. (The command is named “top” because it shows the top users of the system.)

How do I find the top memory consuming process in Unix?
One of the best commands for looking at memory usage is top. One extremely easy way to see what processes are using the most memory is to start top and then press shift+m to switch the order of the processes shown to rank them by the percentage of memory each is using.
What is available memory Linux?
available memory (or free -/+ buffers/cache) is close to zero or is significantly small. swap used values start to increase or fluctuate as there are no free memory pages for the system to use and so it must resort to using the swap disk.

- For remote Linux server use the ssh command for log in purpose.
- Type the ps aux command to see all running process in Linux.
- Alternatively, you can issue the top command or htop command to view running process in Linux.
What is the niceness of the process?
nice is used to invoke a utility or shell script with a particular CPU priority, thus giving the process more or less CPU time than other processes. A niceness of -20 is the highest priority and 19 is the lowest priority. The default niceness for processes is inherited from its parent process and is usually 0.
What is RSS and PSS?
Rss = resident set size. Pss = proportional set size.
