Name
Prometheus Metric Name
tt_fabric_rx_active_bandwidth_megabytes_per_second
Metric Path (tt-telemetry)
Schema:
{hostname}/tray{tray}/chip{chip}/channel{channel}/fabric/tt_fabric_rx_active_bandwidth_megabytes_per_second
Example path:
bh-glx-c09u02/tray1/chip2/channel0/fabric/tt_fabric_rx_active_bandwidth_megabytes_per_second
Description
The receive bandwidth on a specific fabric Ethernet channel in megabytes per second (MB/s), calculated over non-idle (active) cycles only. Unlike tt_fabric_rx_bandwidth_megabytes_per_second, this excludes idle time, giving a measure of the effective throughput when the channel is actively receiving. This metric is available on Wormhole B0 and Blackhole devices.
Note: Fabric metrics are only updated by fabric firmware when workloads are run with fabric telemetry explicitly enabled. For example, by setting the environment variable TT_METAL_FABRIC_TELEMETRY to 1.
Values
Type: Floating Point
Units: Megabytes per second (MB/s)
Allowable values: A non-negative floating-point number representing the active receive bandwidth.
