Name

Prometheus Metric Name

tt_dram_trained

Metric Path (tt-telemetry)

Schema:

{hostname}/tray{tray}/chip{chip}/dram/module{module}/tt_dram_trained

Example path:

bh-glx-c09u02/tray1/chip2/dram/module0/tt_dram_trained

Description

Whether DRAM training succeeded for a specific DRAM module. DRAM training is a calibration process that occurs during device initialization to establish reliable communication between the ASIC and DRAM. This metric is always available on all devices.

Values

Type: Boolean

Units: None

Allowable values:

True (1): DRAM training succeeded and the module is operating normally.
False (0): DRAM training failed. The module may not be functional.
