tt_thermal_throttle_limit_celsius

Metric Path (tt-telemetry)

Schema:

{hostname}/tray{tray}/chip{chip}/tt_thermal_throttle_limit_celsius

Example path:

bh-glx-c09u02/tray1/chip2/tt_thermal_throttle_limit_celsius

Description

The thermal throttle threshold in degrees Celsius. When the ASIC temperature reaches this limit, the device will begin thermal throttling to reduce power and temperature. Compare with tt_asic_temperature_celsius to monitor proximity to the throttle threshold. This metric is only available on devices whose firmware supports reporting the throttle limit.

Values

Type: Floating Point

Units: Degrees Celsius

Allowable values: A floating-point number representing the throttle temperature threshold. For example, 95.0 means the device will begin throttling at 95 degrees Celsius.
