show_fan - checks the fan speed on a node or collection of nodes


MODULE

SYNOPSIS

show_fan [ --help ] [ --db <datasource> ] <--simple|--table> <{device|collection}...>


DESCRIPTION

Check the fan speed on a node or collection of nodes, using whatever server management capability is provided for the deivce.

Since the SrvrMgmt device is reporting the speeds, you need to access the "power" device, not a "node" device. For example: show_fan --simple power.n-1.t-0

All nodes in a collection are done in parallel. Collections named on the command line are done in sequence.


OPTIONS

--db <datasource> Database type and connection information. For GDBM, "GDBM:" followed by the filename of the cluster database to use. For LDAP, the syntax is "LDAP:host:port:dbname"

--simple List device names and fan speed pairs.

--table Generate tab delimited matrix. Parse names by rack and node.

--help Print manpage.


FILES

Paths and other defaults are recorded in CConf.pm.
