System Monitor Reference
The system monitor reports information on system resources:
• number of users, (/system/numUsers) tells you the number of users on a given
node.
• job queues, (/system/jobQueue1Min, /system/jobQueue5Min, and
/system/jobQueue15Min) tells you the number of processes waiting for CPU
and performing disk I/O as an average over 1, 5, and 15 minutes respectively.
This is the same as the load averages reported by uptime (1).
• file system free space, (/system/filesystem/availMb/fsName) tells you the
number of megabytes available for use in each filesystem fsName on the system.

Figure 5-1 shows the system resource monitor hierarchy.
Items in boxes are resource instances that can be monitored. The fsName in italics
changes depending on the names of the file systems.
