Check Container Group Monitor #
The container cloud platform supports the monitoring of cluster inner container groups,including cpu usage, memory usage, network outflow rate and network inflow rate.
Operating steps:
Log in the MSP Platform
In the MSP Platform “All Products” navigation bar,click the Workload under the Container Cloud Platform module
Click select “Pods"and enter Pods list page,select the desired Pods,click Monitor to access the monitor page,as shown in the following figure:
At present,users can also select the required container group in the Deployments,DaemonSets or Pod management page under the node of the workload,and click Monitor to view it.
