The beostat command is a low-level utility that displays data being managed by the Beostat package. This data is collected on each compute node and sent by the sendstats daemon to the recvstats daemon on the master node. Other commands, such as beostatus, present a more user-friendly higher-level picture of the cluster.
The default beostat command shows all available information on all "up" nodes. The --verbose option shows all nodes, including "down" nodes. Various other options constrain the output to show more specific information. You may present multiple options to see multiple data classifications.
The following options are available to the beostat command.
Verbose, display information on all nodes, even if those nodes are down. Normally, beostat displays only "up" nodes.
Show only the data for node NUM rather than for all nodes.
Display the CPU model information.
Display memory statistics.
Display load average information.
Display network interface information.
Display CPU statistics information.
Display root filesystem information.
Display brief help and exit.
Convenience option to display CPU info.
Convenience option to display disk usage of root filesystem.
Convenience option to display network rate of all interfaces.
Convenience option to display number of CPUs more idle than THRES.
Display convenience values (cpupercent, diskusage, netrate, or idle) with no extra text. This eliminates the need to parse the output to obtain the specific values. Only valid when used with one of the convenience options (-C, -D, -R, or -I).
Display program version information and exit.
