About
The Host Information page displays information about a specific host.
The following information are displayed: host name, status, hardware related information, host load and, if defined, information about other resources.
Status
The current status of the host and the sbatchd daemon. Batch jobs can only be dispatched to hosts with an ok status. The possible values for host status are as follows:
- ok
- The host is available to accept batch jobs.
- unavail
- The host is down, or LIM and sbatchd on the host are unreachable.
- unreach
- LIM on the host is running but sbatchd is unreachable.
- closed
- The host is not allowed to accept any remote batch jobs.
- unlicensed
- The host does not have a valid LSF license.
Hardware
Information about the hardware of the host.
The following information are displayed:
- Host type
- The host type as reported by LSF.
- Host model
- The host model as reported by LSF.
- Number of processors
- The number of processors on the host.
- Physical memory
- The maximum amount of physical memory available for user processes.
- Swap space
- The total available swap space.
The hardware section also contains an icon representing the operating system running on the host.
Load
Load information for host.
The following information are displayed:
- Number of users
- The number of current login users.
- CPU utilization
- The CPU utilization exponentially averaged over the last minute, in percentage.
- CPU run queue length averaged over 15 sec
- The 15-second exponentially averaged CPU run queue length.
- CPU run queue length averaged over 1 min
- The 1-minute exponentially averaged CPU run queue length.
- CPU run queue length averaged over 15 min
- The 15-minute exponentially averaged CPU run queue length.
- Available physical memory
- The amount of available physical memory.
- Available swap space
- The amount of available swap space.
- Free space in /tmp
- The amount of free space in /tmp
- Paging rate
- The memory paging rate exponentially averaged over the last minute, in pages per second.
- I/O throughput
- The disk I/O rate exponentially averaged over the last minute, in Kb per second.
- Idle time
- On UNIX, the idle time of the host (keyboard not touched on all logged in sessions), in minutes. On Windows, the idle time index is based on the time a screen saver has been active on the host.
