Viewing detailed server host information
Run bhosts -l host_name and lshosts -l host_name to display all
information about each server host such as the CPU factor and the load thresholds to
start, suspend, and resume jobs. For example:
% bhosts -l hostB
HOST hostB
STATUS CPUF JL/U MAX NJOBS RUN SSUSP USUSP RSV DISPATCH_WINDOWS

Viewing host load by host
The lsload command reports the current status and load levels of hosts in a cluster.
The
lshosts -l command shows the load thresholds.
The
lsmon command provides a dynamic display of the load information. The LSF
administrator can find unavailable or overloaded hosts with these tools.
Run
lsload to see load levels for each host. For example:
% lsload
HOST_NAME status r15s r1m r15m ut pg ls it tmp swp mem
hostD ok 1.3 1.2 0.9 92% 0.0 2 20 5M 148M 88M
hostB -ok 0.1 0.3 0.7 0% 0.0 1 67 45M 25M 34M
hostA busy 8.0 *7.0 4.9 84% 4.6 6 17 1M 81M 27M
The first line lists the load index names, and each following line gives the load levels for
one host.
