tt_ethernet_link_up
Name
Prometheus Metric Name
tt_ethernet_link_up
Metric Path (tt-telemetry)
Schema:
{hostname}/tray{tray}/chip{chip}/channel{channel}/tt_ethernet_link_up
Example path:
bh-glx-c09u02/tray1/chip2/channel0/tt_ethernet_link_up
Description
Whether the Ethernet link is up on a specific channel. This metric reads the link status directly from device memory. The link status is periodically force-refreshed to ensure accuracy. When topology information is available (via Factory System Descriptor), additional labels provide details about the physical port and remote endpoint.
Values
Type: Boolean
Units: None
Allowable values:
True (1): The Ethernet link is up and operational.
False (0): The Ethernet link is down.
