ID: 7390 Title: ipmi_sensors: Stop flooding syslog if no IPMI devices are present Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 In case no IPMI device was present on a system, the system log was flooded with error messages. We no longer call ipmi-sensors if no IPMI devices are found. Considered IPMI devices are all that match "/dev/ipmi*" (in particular /dev/ipmi0, /dev/ipmi/0 and /dev/ipmidev/0).
