Monitoring processor activity

The Support> top command displays the dynamic real-time view of currently running tasks. It shows the resources that users and processes consume at a given time for a specified node.

To use the top command

  • To use the Support> top command, enter the following:
    Support> top [nodename] [iterations] [delay]

    nodename

    Displays the resources and processes at a given time for the specified node.

    iterations

    Specifies the number of iterations you want to run. The default is three.

    delay

    Specifies the delay between screen updates. The default is five seconds.

    For example, to show the dynamic real-time view of tasks running on the node access_01, enter the following:

    Support> top access_01 1 1
top - 16:28:27 up 1 day, 3:32, 4 users, load average: 1.00, 1.00, 1.00
Tasks: 336 total, 1 running, 335 sleeping, 0 stopped, 0 zombie
