DISK I/O BANDWIDTH and NETWORK I/O BANDWIDTH are empty.

Hi,

I tried on different computers the nightly build for jupyter >=4. In all cases the DISK I/O BANDWIDTH and NETWORK I/O BANDWIDTH graphs are empty.

Tested on Ubuntu 22.04 and on a SLURM cluster running JupyterLab inside an Singularity container.

import psutil

# Get CPU usage
cpu_usage = psutil.cpu_percent(interval=1)
print(f"CPU Usage: {cpu_usage}%")

# Get memory usage
memory_info = psutil.virtual_memory()
print(f"Memory Usage: {memory_info.percent}%")

returns

CPU Usage: 3.2%
Memory Usage: 2.0%
