Hi,

I want to make a question about process monitoring.

I want to know if my process are efficient or not. My process is heavy, read a great volume of data, and make a lot of calculations, but I want to know if the process is optimun/efficient using machine resources.

I'm not machine administrator, I have a normal user, when I want to know machive consume I use:

ps -ef | grep user
ps aux | grep user
Uptime
vmstat

Any advice in order to improve process monitoring will be apreciatted. Comands to watch (memory, swapping, cpu use,….) and some help in order to understand this data will be very apreciatted.

Thanks in advance

first stop, you should check out the man pages
of ps, vmstat, uptime

I want to make another question about memory usage.

Using ps command I see three parameteres:

MEM
VSZ
RSS

What are the differences between this parameters. What I want to know is memory RAM usage and swapping. I want to know if my process produce much swapping in memory.

Thanks in advance
