tt_ai_clock_limit_mhz

Metric Path (tt-telemetry)

Schema:

{hostname}/tray{tray}/chip{chip}/tt_ai_clock_limit_mhz

Example path:

bh-glx-c09u02/tray1/chip2/tt_ai_clock_limit_mhz

Description

The AI clock frequency limit in megahertz. This is a hardware limit representing the highest clock frequency the ASIC can run at. When a workload is running on the chip, the clock speed (tt_ai_clock_mhz) will ramp up to this limit value. The current clock speed being at or near this limit is therefore indicative of an active workload.

Values

Type: Unsigned Integer

Units: Megahertz (MHz)

Allowable values: A non-negative integer representing the clock frequency limit. For example, 1500 means the AI clock limit is 1500 MHz.
