TemperatureMonitor
Monitor GPU temperature over time.
This class provides: 1. Continuous temperature monitoring in a background process 2. Timeline export with deduplication 3. Point-in-time temperature queries
Note
The current implementation only supports cases where all GPUs are homogeneous (i.e., the same model).
Warning
Since the monitor spawns child processes, it should not be instantiated as a global variable. Refer to the "Safe importing of main module" section in the Python documentation for more details.

__init__
__init__(
gpu_indices=None,
update_period=1.0,
max_samples_per_gpu=None,
)
Parameters:
Name | Type | Description | Default |
---|---|---|---|
gpu_indices |
list[int] | None
|
Indices of the GPUs to monitor. If None, monitor all GPUs. |
None
|
update_period |
float
|
Update period of the temperature monitor in seconds. Defaults to 1.0 second. Temperature typically doesn't change as rapidly as power, so a longer update period is reasonable. |
1.0
|
max_samples_per_gpu |
int | None
|
Maximum number of temperature samples to keep per GPU in memory. If None (default), unlimited samples are kept. |
None
|
