Name
Prometheus Metric Name
tt_ethernet_retrain_count
Metric Path (tt-telemetry)
Schema:
{hostname}/tray{tray}/chip{chip}/channel{channel}/tt_ethernet_retrain_count
Example path:
bh-glx-c09u02/tray1/chip2/channel0/tt_ethernet_retrain_count
Description
The number of link retraining events that have occurred on a specific Ethernet channel. A retrain happens when the link needs to re-establish synchronization, which can indicate signal integrity issues. This metric reads the retrain count directly from device memory.
Values
Type: Unsigned Integer
Units: None
Allowable values:
A non-negative integer representing the cumulative count of retrain events. A value of 0 indicates no retrains have occurred.
