TIP OF THE WEEK

By Massimo

Working on Ggate: bpstat

The command bpstat can be used to check node status. When run at a shell prompt, bpstat prints out a list of all nodes in the cluster and their current status:

Node(s)                        Status       Mode       User        Group
0-15 up ---x--x--x root root

bpstat can also be used to monitor processes. Entering the command bpstat -p will list all processes running by PID, with the number of the node running each process.

The most useful usage of bpstat is to filter the output of the ps command and pre-pend the node number to it. For this use the option bpstat -P. For example:

ps -ef | bpstat -P
