tt_all_devices_accessible

Metric Path (tt-telemetry)

Schema:

{hostname}/telemetry/tt_all_devices_accessible

Example path:

bh-glx-c09u02/telemetry/tt_all_devices_accessible

Description

Whether all devices on this host are accessible and fully responsive. This provides a system-wide accessibility indicator.

This is the aggregate of the per-device tt_device_accessible metric: it is true only when every device on the host is accessible, meaning that for each device all of its metrics were readable and its PCIe link and all of its NOCs are alive. See tt_device_accessible for the per-device criteria.

If the driver fails to initialize (no devices to collect from), this metric is reported false.

Values

Type: Boolean

Units: None

Allowable values:

  • True (1): All devices are accessible.

  • False (0): One or more devices are not accessible (a metric could not be read, or a PCIe link or NOC appears hung), or the driver failed to initialize.
