High load on the server cause performance degrade. In a Linux server/system we can check the load by different ways. This is a necessary thing to check the load-average on your server for its better and stable performance. Load monitoring in Linux servers – top, w and uptime commands’ usage for checking the load on server How to show process usage for single user with TOP command Top command usages and examples in Unix/Linux PS command usage with example (Unix/Linux) Must try this and comment your suggestions.
You can use the grep command to separate users. To list top 10 Memory consuming processes with user # watch "ps -e -o pmem,pid,user,args|sort -k1 -nr|head -10" To list top 10 CPU usage processes with user # watch "ps -e -o pcpu,pid,user,args|sort -k1 -nr|head -10" You can refer this “ How to show process usage for single user with TOP command” for more details.
To show the process usage of a user with ‘top’ # top -u $username To get a dynamic result you must use the ‘ top‘ command instead of ‘ps’ or use the ‘ watch‘ command along with the ‘ps’. Or # ps -e -o pid,user,args|grep $username To list top 10 Memory consuming processes with user # ps -e -o pmem,pid,user,args|sort -k1 -nr|head -10įind out the top 10 memory consuming process # ps -auxf|sort -nr -k4|head -10įind out every process running under a user # ps -U user-name -u user-name u 🙂 To list top 10 CPU usage processes with user # ps -e -o pcpu,pid,user,args|sort -k1 -nr|head -10įind out top 10 CPU consuming process # ps -auxf|sort -nr -k3|head -10 It’s simply a static output of current resource usage in the server. You can use the grep command to separate users. “ ps command” and “ top command” have a lot of options, here I am explaining some useful command combinations to find the resource(cpu, memory…) usages of users in the server.
