Memory Usage Spike

[Scott Frye_1]

We just had a spike in memory usage, from 74% to 88% (usually hovers around 74%). Are there any commands that show a breakdown of what is using the memory? Especially user memory, and perhaps by process?

Top and glance are both useful for memory usage.

Spikes occur all the time and can be the result of either the programms running or the os monitoring itself.

As long as memory in not consistantly at 100% then all is normally ok.

Hi,

You can use the following command

UNIX95= ps -e -o "vsz ruser args" |sort -n

Note the space between = and ps.

ps command shows how programs use memort, "ipcs -mat" shows shared memory you will need to add these two together to get the user memory usage
