Swapinfo output.

[Adam Winebaugh]

Here is the output from my swapinfo -tam

# swapinfo -tam
Mb Mb Mb PCT START/ Mb
TYPE AVAIL USED FREE USED LIMIT RESERVE PRI NAME
dev 2048 219 1829 11% 0 - 1 /dev/vg00/lvol2
reserve - 428 -428
memory 1537 1410 127 92%
total 3585 2057 1528 57% - 0 -
My memory is at 92% but the system is at 99.9% idle. I am relatively new to HP-UX. How do I find what is using the memory?

Hi

"Memory" in swapinfo is Pseudoswap.

Pseudoswap is nothing but, 75% of your physical memory act as a swap space ( where swap_mem=on )

pseudo swap is only used for reserving a process. fro your output, there is a total of 1537 megs of pseudo swap configured, 1410 megs of pseudo swap are being
used by processes running in memory. The remainder of pseudo swap that it is
not used.system performance would be the same on a system that had 3% or 99% percent of pseudo swap used. It is usually
recommended that the "memory" line simpily be ignored when looking at swapinfo.

It does not mean the physical memory on the system.

Best Regards,
Ramesh

Try top and better yet glance(press m key).

Glance will will give you a memory report

Thanks GUys, that actually makes a lot more sense. I appreciate the help.

top will give you
Memory Data
Includes virtual and real memory in use (with the amount of memory considered "active" in parentheses) and the amount of free memory.

It will also graphically show all processes and the memory they're using.

You can output this to a file. Don't know how readable it will be.

man top

[Adam Winebaugh]

Glance.... I must investigate.

Use "top -f file -n 10000" and it will readable.
