Displays state information and statistics for the specified node.
This command can be run by any Scheduler Administrator.
|NODE||Node name you want to check.|
|-h||Help for this command.|
This command shows detailed state information and statistics for nodes that run jobs (those running LoadL_startd).
NOTEThis command returns an error message if it is run against a scheduling node (one running schedd).
The following information is returned by this command:
|Disk||Disk space available|
|Swap||Swap space available|
|Adapters||Network adapters available|
|Frame||IBM SP frame number associated with node|
|Node||IBM SP node number associated with node|
|StateTime||Time node has been in current state in HH:MM:SS notation|
|Downtime||Displayed only if downtime is scheduled|
|Load||CPU Load (Berkley one-minute load average)|
|TotalTime||Total time node has been detected since statistics initialization expressed in HH:MM:SS notation|
|UpTime||Total time node has been in an available (Non-Down) state since statistics initialization expressed in HH:MM:SS notation (percent of time up: UpTime/TotalTime)|
|BusyTime||Total time node has been busy (allocated to active jobs) since statistics initialization expressed in HH:MM:SS notation (percent of time busy: BusyTime/TotalTime)|
After displaying this information, some analysis is performed and any unusual conditions are reported.

Further information about node status can be found using the showstate command.
You can determine scheduling nodes with the LoadLeveler llstatus command (nodes that have Avail in the Schedd column).
