How could we get the GCP VM instance file descriptors metrics from stackdriver agent?

I am surprised that there is no file descriptor item for compute

The GCP compute metrics are not sent by the agent, but by the GCE infrastructure. The agent metrics are at https://cloud.google.com/monitoring/api/metrics_agent.
However, they indeed don't contain the count of open file descriptors.

The per-process file descriptors will eventually be available from the processes plugin, but that would require a major version release of the Stackdriver monitoring agent. We don't currently have an ETA for that.
For VM-level open file descriptors counts, you could use something like this with the Custom metrics from the agent mechanism, which will add Stackdriver custom metrics in your project.
Hope this helps.

I did some research:

the limit of one process would be the one we want to monitor.
And, it referred to pre-process file descriptors
