From shell you can use 'top' command
or read /proc/meminfo
From Grafical Interface there are many tools for monitor a linux box, one of these is gkrellm (http://www.gkrellm.net/). This tool monitor CPU, MEM, FileSystem, Network, etc....

We can memory informations with top for most using process? It is also containing the service informations too.

Some sort of scripting to pipe the top output and get only service memory usage informations.

As like,

top -d 1 -n 100 -f /tmp/topoutput

It will contain 100 process informations there.

If you have RH and installed the System Tools/System Monitor, this will also give you the info you seek.

For automateted monitoring use a cron-script like this:

top -n 1 -b -p `pidof -s PROCESSNAME` | tail -2 | mail -s "Top Information for process PROCESSNAME" your@e-mail.address

top -n 1 -b -p blabla
---------------------
-n 1: top runs once then exits
-b: for dumb terminals, don't use escaps (for colouring terminal for example)
-p Number: wich PID to show (this switch could be used up to 20 times per top
`pidof -s PROCNAME`: searches for the first process with the name PROCNAME and returns its PID

tail -2
-------

-2: show the last 2 lines of output. if you are using more then one -p argument at top, you should increase the value to -3, -4, ...

mail -s "blabla" e-mail
-----------------------

-s "blabla": the subject for the e-mail
e-mail: your e-mail address
