Memory Usage in Linux

Is there a good tool that can monitor memory usage in linux. Maybe even one that generates a graphical display?

Thanks,

T.J.

The sar command from the sysstat package, vmstat, the free and top commands are command line utilities to display memory usage.

You can also use mrtg, nagios or another rrdtool or monitoring software to graphic the memory usage in a monitoring server.

Ganglia is another good monitoring software.

gpm if installed has some decent tools for memory monitoring.

sar also does.

Glance from HP costs money but has been ported to Linux and provides EXCELLENT displays.

you can export sar, or top to a txt to make graphs in excel or something like that, but if you want online graphical reporting and you can spent some money I think Glance is the betther choice.
