msgb -group HOSTGROUP
The msgb program is to display the locking status of compute hosts specified with the HOSTGROUP argument. The host locking information is managed by the msgbserv(8) daemon process. Cluster hosts can be locked by the scout(1), or msgblock(1) command.
This program is written in the Tcl/Tk programming language and it can also accept typical X-window application programs. For example, the -g option is to specify the geometory of the msgb window.
If the DISPLAY environment is not set properly, then the msgb program output the locking status in plain text.
