tt_fan_speed_percent
Metric Path (tt-telemetry)
Schema:
{hostname}/tray{tray}/chip{chip}/fan{fan}/tt_fan_speed_percent
Example path:
bh-glx-c09u02/tray1/chip2/fan0/tt_fan_speed_percent
Description
The fan speed as a percentage of maximum. This value is read from ARC firmware telemetry. A separate metric is created for each fan the device reports (fan0, fan1, …), where the number is the fan’s index in the ARC firmware’s fan array. This metric is only created for fan slots that report speed data; devices that report no fans produce no metrics.
Values
Type: Unsigned Integer
Units: Percent (%)
Allowable values:
A value from 0 to 100 representing the fan speed as a percentage of its maximum. For example, 75 means the fan is running at 75% speed.
