tt_dram_corrected_edc_write_errors

Metric Path (tt-telemetry)

Schema:

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

Example path:

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

Description

The cumulative count of corrected EDC (Error Detection and Correction) write errors for a DRAM module. These are errors that were detected and corrected by the DRAM’s error correction mechanism during write operations. The counter saturates at 255. This metric is only created if GDDR telemetry is available on the device.

Values

Type: Unsigned Integer

Units: None

Allowable values: A non-negative integer from 0 to 255. A value of 0 indicates no corrected write errors. The counter saturates at 255 and will not increment further.
