Swap space (swp)
The swp index gives the currently available virtual memory (swap space) in MB. This
represents the largest process that can be started on the host.
Memory (mem)
The mem index is an estimate of the real memory currently available to user processes.
This represents the approximate size of the largest process that could be started on a
host without causing the host to start paging.
LIM reports the amount of free memory available. LSF calculates free memory as a sum
of physical free memory, cached memory, buffered memory and an adjustment value.
The command
vmstat also reports free memory but displays these values separately.
There may be a difference between the free memory reported by LIM and the free
memory reported by
vmstat because of virtual memory behavior variations among
operating systems. You can write an ELIM that overrides the free memory values
returned by LIM.
I/O rate (io)
The io index measures I/O throughput to disks attached directly to this host, in KB per
second. It does not include I/O to disks that are mounted from other hosts.
Viewing information about load indices
lsinfo -l
The lsinfo -l command displays all information available about load indices in the
system. You can also specify load indices on the command line to display information
about selected indices:
% lsinfo -l swp
RESOURCE_NAME: swp
DESCRIPTION: Available swap space (Mbytes) (alias: swap)
TYPE ORDER INTERVAL BUILTIN DYNAMIC RELEASE
Numeric Dec 60 Yes Yes NO
lsload -l
The lsload -l command displays the values of all load indices. External load indices
are configured by your LSF administrator:
% lsload
HOST_NAME status r15s r1m r15m ut pg ls it tmp swp mem
hostN ok 0.0 0.0 0.1 1% 0.0 1 224 43M 67M 3M
