Hi,

I'm trying to look at the Linux server memory utilization. I don't see any thing on the graph. Can any one guide me on this.

Thanks,

you can use vmstat command.
you may keep the command running and output to a log file. You can use the log file to generate a graph in Excel.

If you need graphs, you can use MRTG or Cacti to poll memory usage and create graphs.

Check Cacti here:

If you just want to see the memory usage in command line, theres a nice tool called top.

Htop is nice.

http://htop.sourceforge.net/

It shows memory usage (system, swap, buffers) in a sort of a graph.
