Fan

This class creates monitoring objects for each cooling sensor it discovers. Depending on the system and the data available, one or more parameters will be associated to the fan monitoring. Critical devices like processors, power supplies etc, have fans to avoid over-heating. Monitoring fans is important because they ensure a proper temperature for the system to work efficiently.

Depending on the available information, the Speed and/or Status parameters will be displayed for each detected fan device:

●The Speed parameter represents the speed of the corresponding fan (in rotations/minute). An alert is raised through Status if the fan speed is too low for proper functioning.

●The Speed Percent parameter represents the speed of the corresponding fan in percentage of its maximal speed.

●The Status parameter represents the overall status of the fan. An alert is triggered if the fan stops spinning or does not spin fast enough.

Parameters

Name	Description	Unit	Alert Conditions
Locator	Helps to physically locate a component.	n/a	n/a
Speed	Speed of the fan.	Rotation Per Minute (RPM)	n/a
Speed Percent	Speed of the fan as a percentage of its maximal speed.	Percent (%) of maximal speed	n/a
Status	Status of the fan. Example: “OK” or “Alarm!! This fan is not detected anymore”	Values: OK; Warning; Alarm	Warning = “!” Alarm = “!!”

"Status" is a text parameter that describes the overall status of the corresponding device or sensor. Alert conditions describe in symbolic terms what occurs in the parameter when thresholds are breached: one exclamation mark triggers a warning; two exclamation marks raise an alarm.

Example

If BPM Express for Hardware detects that a fan has breached manufacturer-specified thresholds, the Status parameter will report “Warning! This fan is degraded/is about to fail” or “Alarm!! This fan is not detected anymore", as may be the case. The history graph shows the exact details of the problem, its consequences and recommended actions.

Depending on your system, all parameters may not be used.
