Memory

[Frédéric Devos]

We have 4GBytes memory. We want to know the current usage to see if there is space to add another important memory consuming process.
We have tried different command but are getting confused about the meaning of the various numbers.

Hi there.
Try to install glance trial version from the application cd. That will give you a real overview. If you like that tool, think about a license.

Hi
you could also evaluate PerfView and MeasureWare

MeasureWare is able to collect metrics representing system usage and workload for each subsystem (swap,CPU,memory,network)

PerfView is a graphical tool able to make graphics from collection data collected by MeasureWare.
