1 title: Dell PowerConnect Switches: FAN sensors
3 catalog: hw/network/dell
7 This check monitors the various FAN sensors on a Dell PowerConnect switch that supports
8 the DELL-VENDOR-MIB. It will monitor the state of the FAN itself, depending on the
9 state returned by the FAN.
11 If a switch has more then one FAN sensor, it will create a service for EACH sensor.
12 However, if a switch has any FANS that are not connected up to the sensor suite, or
13 there is an empty FAN bay, they will not be picked up by this check.
15 A FAN that is running normally will return an OK nagios state. Any FAN that
16 are in a warning or is not present (if it was previously present) will return a WARNING
17 nagios state. If a FAN is in a critical or is non-functional according to the sensor will
18 return a CRITICAL nagios state. Lastly, if a FAN is in a "shutdown" state, it will return
19 an UNKNOWN nagios state.
21 Currently, testing has been completed with the Dell PowerConnect 5448 and 5424 models,
22 however the service check may work with other models.
25 During the inventory phase of check_mk, it will create one or more service {Sensor fanX_unitX}
26 entries, as long as the MIB defined above is supported on the switch.
29 If a switch has 3 FANS in the device, it will create 3 service entries titled:
35 The fanX value represents the selected FAN, where as the unitX values represents the sensor
36 assigned to the FAN. It is possible to have multiple sensors on a single FAN, though I have
