The following information is returned by this command:
| Name | Description |
|---|---|
| Disk | Disk space available |
| Memory | Memory available |
| Swap | Swap space available |
| State | Node state |
| Opsys | Operating system |
| Arch | Architecture |
| Adapters | Network adapters available |
| Features | Features available |
| Classes | Classes available |
| 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) |
| ActiveTime | 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) |
| EffNodeAccessPolicy | Configured effective node access policy |
After displaying this information, some analysis is performed and any unusual conditions are reported.
