# tt_vcore_v [<< Home](../index.md) | [<< Metrics](../metrics.md) ## Name ### Prometheus Metric Name ``` tt_vcore_v ``` ### Metric Path (tt-telemetry) Schema: ``` {hostname}/tray{tray}/chip{chip}/tt_vcore_v ``` Example path: ``` bh-glx-c09u02/tray1/chip2/tt_vcore_v ``` ## Description The core voltage of the ASIC in volts. The raw value from ARC firmware telemetry is in millivolts and is converted to volts (divided by 1000). This metric is only created if the device reports core voltage data. ## Values **Type:** Floating Point **Units:** Volts (V) **Allowable values:** A floating-point number representing the core voltage. For example, `0.85` means the core voltage is 850 millivolts. ## Prometheus Labels |Label Name|Value| |---|---| |hostname|The host from which the metric was collected.| |hall|The datacenter hall where the host is located. Sourced from the Factory System Descriptor (FSD).| |aisle|The datacenter aisle where the host is located. Sourced from the Factory System Descriptor (FSD).| |rack|The rack number where the host is located. Sourced from the Factory System Descriptor (FSD).| |shelf_u|The shelf U position in the rack where the host is located. Sourced from the Factory System Descriptor (FSD).| |tray|The tray (UBB) that the device is located on.| |chip|The ASIC location within the tray.| |unit|The unit of measurement. Always `"V"` for this metric.|
