tt_gddr_max_temperature_celsius

Metric Path (tt-telemetry)

Schema:

{hostname}/tray{tray}/chip{chip}/dram/tt_gddr_max_temperature_celsius

Example path:

bh-glx-c09u02/tray1/chip2/dram/tt_gddr_max_temperature_celsius

Description

The current maximum DRAM (GDDR) temperature observed across all modules in degrees Celsius. This is a chip-level aggregate representing the hottest DRAM module. Compare with per-module GDDR temperature metrics for finer-grained monitoring. This metric is only available on devices whose firmware supports reporting the maximum DRAM temperature.

Values

Type: Floating Point

Units: Degrees Celsius

Allowable values: A floating-point number representing the maximum DRAM temperature. For example, 78.5 means the hottest DRAM module is at 78.5 degrees Celsius.
