Getting very high CPU usage results in node exporter

[sao cao đăng]

Hi, Some one can help me with this issue. Thanks a lot.

What did you do?
I setup node-exporter and docker container individually on each node and used prometheus as my database and grafana to graph the data. This worked fine, so I can launch all the containers using services in my swarm. For some reason my CPU usage is 600% and higher.
What did you expect to see?
I expect to see around 30% cpu usage like i saw earlier when i installed node-exporter and docker containers on each node.
What did you see instead? Under which circumstances?
High CPU suage > 600%
Environment
Docker

System information:

Linux 3.10.0-1127.el7.86_64

Node exporter information:
version 0.18.1 (branch: HEAD, revision:3db77732e925c08f675d7404a8c46466b2ece83e
