count [hw hw]

List the status of the communication system(s) on the selected node(s). Various counters are displayed.

If the hw option is given, only the counters concerning the hw hardware type are displayed. The default is to display the counters of all enabled hardware types on this node.

down

List all nodes which are marked as "DOWN".

hardware

Show the hardware setup on the selected node(s).

Besides the types of the communication hardware enabled within the ParaStation system on each node also the number of available CPUs are displayed. The two numbers shown in this column mark the number of virtual and physical CPUs respectively. These number might differ due to technologies like Intel's HyperThreading or multi core CPUs.

load

Show the load and the number of processes managed by the ParaStation system on the selected node(s).

The three load values displayed are the averages for 1, 5 and 15 minutes respectively. The two numbers of processes are as follows: The total number of processes contains all processes managed by the ParaStation system, including Logger, Forwarder and psiadmin(1) processes. Furthermore of course the actual working processes started by the users are included. The latter ones are the “normal” processes, additionally displayed in the last column of the output.

mcast

List the status of the MCast facility of the ParaStation daemon psid(8) on the selected node(s).

memory

Show the overall and available memory on the selected node(s).

node

List the status of the selected node(s). Depending on the state of the ParaStation daemons, the node(s) are marked to be "UP" or "DOWN".

proc [cnt count]

Show the processes managed by the ParaStation system on the selected node(s).

Only user, logger and admin processes are displayed. If forwarder and other special processes should also be displayed, use the list allproc directive.

Up to count processes per node are displayed. If more processes are controlled by ParaStation on this node, a short remark will tell the number of not displayed processes. The default is to show 10 processes.

The listed fields have the following meaning:

Node

The ParaStation ID of the node the process is running on.
