displays load information for LSF hosts and periodically updates the display
lsmon is a full-screen LSF monitoring utility that displays and updates load information for hosts in a cluster.
By default, displays load information for all hosts in the cluster, up to the number of lines that fit on-screen.
By default, displays raw load indices.
By default, load information is sorted according to CPU and paging load.
Displays effective CPU run queue length load indices. Options -N and -E are mutually exclusive.
Displays only load information for the requested number of hosts. Information for up to num_hosts hosts that best satisfy resource requirements is displayed.
Displays only load information for hosts that satisfy the specified resource requirements. See Administering Platform LSF for a list of built-in resource names.
Load information for the hosts is sorted according to load on the specified resources.
If res_req contains special resource names, only load information for hosts that provide these resources is displayed (use lshosts to find out what resources are available on each host).
If one or more host names are specified, only load information for the hosts that satisfy the resource requirements is displayed.
Displays only load information for the specified load indices. Load index names must be separated by a colon (for example, r1m:pg:ut).
If the index list index_list is too long to fit in the screen of the user who invoked the command, the output is truncated. For example, if the invoker's screen is 80 characters wide, then up to 10 load indices are displayed.
Sets how often load information is updated on-screen, in seconds.
Saves load information in the specified file while it is displayed on-screen.
If you do not want load information to be displayed on your screen at the same time, use lsmon -L file_name < /dev/null. The format of the file is described in lim.acct(5).
The following fields are displayed by default.
Name of specified hosts for which load information is displayed, or if resource requirements were specified, name of hosts that satisfied the specified resource requirement and for which load information is displayed.
Status of the host. A minus sign (-) may precede the status, indicating that the Remote Execution Server (RES) on the host is not running.
The host is in normal load sharing state and can accept remote jobs.
The host is overloaded because some load indices exceed configured thresholds. Load index values that caused the host to be busy are preceded by an asterisk (*). Built-in load indices include r15s, r1m, r15m, ut, pg, io, ls, it, swp, mem and tmp (see below). External load indices are configured in the file lsf.cluster.cluster_name.
The host is locked by its run window. Run windows for a host are specified in lsf.conf and can be displayed by lshosts. A locked host does not accept load shared jobs from other hosts.
The host is down or the Load Information Manager (LIM) on the host is not running.
The CPU utilization exponentially averaged over the last minute, between 0 and 1.
The memory paging rate exponentially averaged over the last minute, in pages per second.
On UNIX, the idle time of the host (keyboard not touched on all logged in sessions), in minutes.
On Windows, the it index is based on the time a screen saver has been active on a particular host.
