Python Docker: Get Containers memory usage, CPU percentage programmatically in python docker

Question

As command "docker stats" gives details like:(I have put just header, not values)

CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS

I want the above details using python script. I have done following:

client = docker.DockerClient(base_url='unix:///var/run/docker.sock') for i in client.containers.list(): print(i.stats)

But not getting any useful information using i.stats and it's attribute. What should I do to get above details?

stats is a function. So you need to call it as i.stats(). It also streams the result by default as a python generator. If you want to get the current stats only, you can use the stream=False parameter.

client = docker.DockerClient(base_url='unix:///var/run/docker.sock') for i in client.containers.list(): print(i.stats(stream=False))

If you want to keep printing the stats realtime:

for stat in i.stats(): print(stat)
