Operating Systems Solaris Physical and Free mem on TOP command Post 302740351 by jlliagre on Thursday 6th of December 2012 04:27:23 AM

Don't use top on Solaris. It is not delivered with the OS and might report bogus or inaccurate data.

Use vmstat 2 2 to get free virtual and physical memory.
Use prstat -Z to get per process and global memory usage.
Use pmap -x pid to get detailed memory usage for a single process.
Use echo ::memstat | mdb -k to get RAM usage.
Use swap -s to get virtual memory usage.

NAME
pmap - display information about process memory mappings SYNOPSIS
pmap [ -d | -q | -h | -V | -A low,high ] pid DESCRIPTION
pmap(1) displays information about a process's memory mappings, such as its stack, data segment, mapped files, and so on. The pmap(1) utility will show, for each mapping of a given process, the starting byte address in the process's address space, the size, the RSS (size of the mapping in physical memory), the amount of dirty pages, the permission, the device node, the offset, and the file backing the mapping, if any. As the last line of output, the pmap(1) utility will tally up the total size of all mappings as well as show the total size of writable/private mappings and of shared mappings. OPTIONS
d, --device Display major and minor device numbers. A, --limit=low,high Limit results to the given range. q, --quiet Hide header and memory statistics. h, --help Show pmap usage. V, --version Display version information. FILES
