我能否从 Prometheus 的以下指标中找出 GPU 利用率百分比？我不知道如何查询它。我没有 PPC64lE 环境的 dcgm-exporter 映像。您还可以共享链接以制作 ppc64le 环境的 dcgm-exporter 的 docker 映像

根据您分享的指标，以下指标将为您提供有关 GPU 利用率的信息：

nvidia_gpu_duty_cycle- 在过去的采样周期中，一个或多个内核在 GPU 设备上执行的时间百分比

nvidia_gpu_memory_total_bytes- GPU 设备可用的总内存（以字节为单位）

nvidia_gpu_memory_used_bytes- GPU 设备使用的内存（以字节为单位）

nvidia_gpu_num_devices- GPU 设备数量

nvidia_gpu_power_usage_milliwatts- GPU 设备的功耗（以毫瓦为单位）

nvidia_gpu_temperature_celsius- GPU 设备的温度（以摄氏度为单位）

在 Prometheus UI 或以 Prometheus 作为数据源的 Grafana 中，这些值可用于您的查询表达式中以检索关联的 GPU 指标。例如，如果您要执行一个简单的查询nvidia_gpu_memory_total_bytes，它将返回与该指标名称匹配的所有时间序列。

另请注意，您共享的指标包含上述每个值的 4 个条目，每个可用的 GPU 设备一个，编号为0-3。如果您只想查询特定设备的指标，假设 #2，您的查询需要如下所示nvidia_gpu_memory_total_bytes{minor_number="2"}：请注意每个指标名称后面之间的各种逗号分隔标签，{}因为它们可用于根据您的喜好过滤查询。有关 Prometheus 查询的更多信息，请点击此处。

就其本身而言，您可以使用来自官方github repoDCGM的源代码专门为 PPC64IE 构建 Docker 映像。这些说明将首先让您创建一个单独的 Docker 映像，该映像将用于生成 DCGM 构建。在生成 DCGM 构建时，您需要在执行脚本以针对 PPC64IE 时包含该选项。--arch ppc./build.sh

对于dcgm-exporter( github )，NVIDIA 在其Docker Hub 存储库中提供了许多预构建的图像，并在此处找到了官方文档。
