This utility displays the BProc status of cluster nodes, and processes running on those nodes. Node information includes the node's IP address, state, user ownership, group ownership, and running node user processes.
The following options are available to the bpstat program.
Print the command usage message and exit. If -h is the first option, all other options will be ignored. If -h is not the first option, the other options will be parsed up to the -h option, and those options will be processed.
Print the command version number and exit. If -V is the first option, all other options will be ignored. If -V is not the first option, the other options will be parsed up to the -V option, and those options will be processed.
Continuously update the status; otherwise, print status once and exit.
Print compacted listing of nodes (default).
Print long list of node status. This includes IP address, status, mode, user and group information.
Prints the IP address of the indicated node.
Prints the state for the indicated node. The BProc states are "down", "boot", "error", "unavailable", "up", "reboot", "halt", and "pwroff".
Prints the node numbers that are being used and/or are available for the nodes in the cluster.
Prints the total number of nodes configured for the cluster. The number is calculated from the cluster configuration in the /etc/beowulf/config file. Note that this is the potential size of the cluster, not the current number of available nodes or the count of machines assigned node numbers.
Prints the node list in reverse sorted order.
Prints the node list sorted by node number.
Prints the node list sorted by node status.
Prints the nodes in the order returned by the system (no sorting is done).
Prints the node number that corresponds to the specified hostname or IP address.
Prints a list of processes (by PID) that are currently running on the specified node.
Postprocesses the output from the ps command, prepending the node number that BProc-controlled processes are running on. This is typically used as ps -aux | bpstat -P. Processes not controlled by the BProc system will not have a number appended. If nodes is supplied, then the ps output is filtered to show only the specified node(s). Node(s) can be identified by names, numbers, or a list of numbers.
Optionally, specify the nodes for which information is to be displayed. Nodes can be specified individually, in a list, or as ranges. Alternatively, allup specifies all nodes that are in an up state.
Print the number of available nodes:
[user@cluster user] $ bpstat --total allup 9 |
Generate a list of all usable nodes:
[user@cluster user] $ bpstat --number allup
0 1 2 4 5 10 16 17 20
[user@cluster user] $ bpstat --number allup | awk '{ print "."$1 }'
.0 .1 .2 .4 .5 .10 .16 .17 .20 |
Print status for all nodes:
[user@cluster user] $ bpstat Node(s) Status Mode User Group 8,11,22-31 down ---------- root root 3,6-7,9,12-15,18-19,21 error ---x------ root root 0-2,4-5,10,16-17,20 up ---x--x--x root root |
Print the PIDs and associated node number of currently running processes:
[user@cluster user] $ bpstat -p PID Node 7503 0 8262 1 |
Print status for specific nodes:
[user@cluster user] $ bpstat 0-2,3,8 Node(s) Status Mode User Group 8 down ---------- root root 3 error ---x------ root root 0-2 up ---x--x--x root root |
Augment ps aux for node numbers:
[user@cluster user] $ ps aux | bpstat -P
NODE USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 1 0.0 0.0 4756 552 ? S 10:58 0:02 init [5]
root 2 0.0 0.0 0 0 ? S 10:58 0:00 [migration/0]
(etc.) |
Filter ps aux for nodes n1 and n2:
[user@cluster user] $ ps aux | bpstat -P n1,n2 NODE USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND 1 root 1328 0.0 0.0 6864 692 ? Ss 12:45 0:00 [portmap] 2 root 32397 0.0 0.0 6864 692 ? Ss 12:45 0:00 [portmap] |
