Key Error: Online CPU's

[ninjakitteh69]

Hi.
When running the script, I get the following Error message:
`Exception in thread worker-0:
Traceback (most recent call last):
File "./docker_check.py", line 51, in get_cpu_pct
online_cpus = stats['cpu_stats']['online_cpus']
KeyError: 'online_cpus'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "/usr/lib64/python3.6/threading.py", line 916, in _bootstrap_inner
self.run()
File "/usr/lib64/python3.6/threading.py", line 864, in run
self._target(*self._args, **self._kwargs)
File "./docker_check.py", line 98, in get_ct_metrics
cpu_pct = get_cpu_pct(stats)
File "./docker_check.py", line 54, in get_cpu_pct
for item in stats['cpu_stats']['percpu_usage']
KeyError: 'percpu_usage'
`
I tried printing out the stats array and see that online_cpu's does not exist as an object. heres the info I received in the stats array:

I am using an Ec2 instance on aws to run the container and have installed docker via pip like in the docs. Please let me know if you require anymore info
