This topic describes how to view the details of containers.

Go to the container details page

  1. Log on to the ARMS console.
  2. In the left-side navigation pane, click Container Monitoring.
  3. In the top navigation bar of the MNS console, select the region where your cluster is deployed.
  4. On the Container Monitoring page, click the name of a Kubernetes cluster.
  5. In the Namespace section of the Cluster Resources page, click the intersection of a namespace and a resource type.
    Note
    • If you click an area in blue, all resources of the selected type within the selected namespace are displayed.
    • If you click an area in red, the abnormal resources of the selected type within the selected namespace are displayed.
  6. Click the Pod tab.
  7. On the Pod tab, click the name of the pod that you want to view.
  8. In the Container list section of the pod details page, click the name of the container that you want to view.

Basic information

In the basic information section, you can view the following information about the selected container: the number of requests, number of errors, average response time, number of slow calls, number of containers, number of restarts, and execution duration.

In the basic information section, you can perform the following operations:
  • Click Log to view the logs of the container.
  • Click Terminal to log on to the terminal of the container.

Number of requests, response time, number of errors, and number of slow calls

Container monitoring allows you to view the following protocol-related metrics for a container: the number of requests, response time, number of errors, and number of slow calls.

You can click the name of a protocol to view these metrics related to the protocol. For more information about the protocol-related metrics that you can view, see Protocol-related metrics.

CPU and memory

In the CPU and Memory sections, you can view the limits on CPU cores and memory, and time series curves of and statistics on the CPU utilization, memory usage, number of requested CPU cores, amount of requested memory, number of limited CPU cores, and amount of limited memory.

Container monitoring - Pod details - CPU and memory

In the CPU and Memory sections, you can perform the following operations:

  • Move the pointer over the curve of a metric to view the specific statistics at the specified point in time.

  • Click a metric in the upper-right corner of a chart to hide or show the curve of the metric.

Number of limited CPU cores and number of failed memory allocation requests

In the CPU Throttled section, you can view the time series curve of the number of CPU cores limited because the current CPU utilization exceeds the upper limit.

In the Memory FailCnt section, you can view the time series curve of the number of memory allocation requests failed because the current memory usage exceeds the upper limit.

Node

In the Node section, you can view the following information about the node that hosts the container: node name, and time series curves of and statistics on the CPU utilization, memory usage, disk usage, and network traffic.
