Yes, you can monitor GPU's performance using Stackdriver.
To review GPU metrics using Stackdriver, complete the following steps:
On each VM instance, set up the GPU metrics reporting script. This script performs the following tasks:
Installs the GPU metrics reporting agent. This agent runs at intervals on the instance to collect GPU data, and sends this data to Stackdriver.
Creates a custom/gpu_utilization metrics field in Stackdriver. This field stores GPU specific data that you can analyze in Stackdriver.
View logs in Stackdriver.
