1 title: Dell PowerConnect Switches: Power Supply Sensors
3 catalog: hw/network/dell
7 This check monitors the various PSU sensors on a Dell PowerConnect switch that supports
8 the DELL-VENDOR-MIB. It will monitor the state of the PSU itself, depending on the
9 state returned by the PSU.
11 If a switch has more then one PSU sensor, it will create a service for EACH sensor.
12 However, if a switch has any PSU units that are not connected up to the sensor suite, or
13 there is an empty PSU bay, they will not be ignored by this check.
15 A PSU that is running normally will return an OK nagios state. Any PSU that
16 are in a warning or is not present (if it was previously present) will return a WARNING
17 nagios state. If a PSU is in a critical or is non-functional according to the sensor will
18 return a CRITICAL nagios state. Lastly, if a PSU is in a "shutdown" state, it will return
19 an UNKNOWN nagios state.
21 The service will show the state of the PSU, as well as the power source state. The source
22 of the power can be one of the following:
27 - External Power Supply
30 Currently, testing has been completed with the Dell PowerConnect 5448 and 5424 models,
31 however the service check may work with other models.
34 During the inventory phase of check_mk, it will create one or more service {Sensor psX_unitX}
35 entries, as long as the MIB defined above is supported on the switch.
38 If a switch has 2 PSU devices in the device, it may create one service for each PSU, or a single
39 service that indicates the PSU devices are connected internally, in a redundant state. The
40 result is strictly determined in what the SNMP service provides to the check.
42 The psX value represents the selected PSU, where as the unitX values represents the sensor
43 assigned to the PSU. It is possible to have multiple sensors on a single PSU, though I have
