DESCRIPTION
|
|
||||||
|
|
||||||
A Munin plugin to graph the fan speeds and chassis temperatures of Dell
|
|
||||||
hardware. Requires Dell's OpenManage software, specifically omreport. OMSA
|
|
||||||
services must be started prior to plugins use. Script expects omreport to
|
|
||||||
be in /usr/sbin/, you may need to add a symlink.
|
|
||||||
|
|
||||||
omreport accesses the proc filesystem and as such this plugin must be ran
|
|
||||||
as root. Alternatively, you could modify script to use sudoers, or setuid.
|
|
||||||
|
|
||||||
To run script as root add the following lines to munin's plugin-conf.d dir.
