## Name

### Prometheus Metric Name

```
tt_asic_temperature_celsius
```

### Metric Path (tt-telemetry)

Schema:

```
{hostname}/tray{tray}/chip{chip}/tt_asic_temperature_celsius
```

Example path:

```
bh-glx-c09u02/tray1/chip2/tt_asic_temperature_celsius

## Description

The ASIC die temperature in degrees Celsius. This is the primary temperature measurement for the chip and is always available on all devices. It is read from ARC firmware telemetry.

## Values

**Type:** Floating Point

**Units:** Degrees Celsius

**Allowable values:**
A floating-point number representing the chip temperature. For example, `65.5` means the ASIC is at 65.5 degrees Celsius.
