Collecting Docker Container Metrics with cAdvisor

cAdvisor · 发表于 2022-1-25 10:32:09

Requirement: Check the status of a docker container, collect various container metrics, search for "container_exporter", found: https: //github.com/docker-archive/infra-container_ We found that exporter has been deprecated, and we recommend using "cAdvisor".

cAdvisor (Container Advisor)

GitHub address: https: //github.com/google/cadvisor

Documentation: https: //github.com/google/cadvisor/blob/master/docs/running.md

cAdvisor (Container Advisor) lets container users understand the resource usage and performance characteristics of the containers they are running. It is a running daemon that collects, aggregates, processes, and exports information about running containers. Specifically, it saves resource isolation parameters, historical resource usage, histograms of complete historical resource usage, and network statistics for each container. This data is exported container- and machine-wide.

The Docker Direct View Container Resource Consumption command is as follows:
