lim Load Information Manager (LIM) running on each server host. Collects host load
and configuration information and forwards it to the master LIM running on the

ncpus) change. Static indices are:
◆ Number of CPUs (ncpus)
◆ Number of disks (ndisks)
◆ Total available memory (maxmem)
◆ Total available swap (maxswp)
◆ Total available temp (maxtmp)
◆ The number of physical processors per CPU configured on a host (nprocs).
◆ The number of cores per processor configured on a host (ncores).
◆ The number of threads per core configured on a host (nthreads).
Dynamic indices for host load collected at regular intervals are:
◆ Hosts status (status)
◆ 15 second, 1 minute, and 15 minute run queue lengths (r15s, r1m, and r15m)
◆ CPU utilization (ut)
◆ Paging rate (pg)
◆ Number of login sessions (ls)
◆ Interactive idle time (it)
◆ Available swap space (swp)
◆ Available memory (mem)
◆ Available temp space (tmp)
◆ Disk IO rate (io)
Commands:
◆ lsadmin limstartup—Starts LIM
