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 the Kubernetes cluster whose containers you want to view.
  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 whose containers 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 requests, amount of CPU cores limited, number of failed memory allocation requests, and execution duration.

Container monitoring - Container details - Basic information
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

In the Requests section, you can view the time series curve of the number of requests, and the top N API operations by the number of requests.

Container monitoring - Container details - Number of requests and response time
In the Requests section, you can perform the following operations:
  • Move the pointer over the curve to view the specific statistic at the specified point in time.
  • Use the mouse to select a time range in the chart to view the specific statistics in the specified time range.
  • In the API operation list, select an option from the drop-down list to view the top 5, 10, or 15 API operations by the number of requests sent to the container. Click View list in the Operation column of an API operation to view the request details of the API operation. For more information, see API operation details.

Response time

In the Response Time section, you can view the time series curves of the average response time and 95th percentile response time, and the top N API operations by average response time.

In the Response Time section, you can perform the following operations:
  • Move the pointer over the curve of a metric to view the specific statistic at the specified point in time.
  • Use the mouse to select a time range in the chart to view the specific statistics in the specified time range.
  • In the API operation list, select an option from the drop-down list to view the top 5, 10, or 15 API operations by average response time. Click View list in the Operation column of an API operation to view the request details of the API operation. For more information, see API operation details.

Number of errors and number of slow requests

In the Number of errors and Slow Calls sections, you can view the time series curves of the number of errors and number of slow requests, and the top N API operations.

Container monitoring - Container details - Number of errors and number of slow requests
In the Number of errors and Slow Calls sections, you can perform the following operations:
  • Move the pointer over the curve of a metric to view the specific statistic at the specified point in time.
  • Use the mouse to select a time range in a chart to view the specific statistics in the specified time range.
  • In an API operation list, select an option from the drop-down list to view the top 5, 10, or 15 API operations by the number of errors or number of slow requests. Click View list in the Operation column of an API operation to view the request details of the API operation. For more information, see API operation details.

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, amount of requested CPU cores, amount of requested memory, amount of limited CPU cores, and amount of limited memory.

Container monitoring - Container 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 statistic 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.

Amount 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 amount 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.

Container monitoring - Container details - CPU Throttled

In the CPU Throttled and Memory FailCnt sections, you can perform the following operation:

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

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.

Container monitoring - Container details - Node
In the Node section, you can perform the following operations:
  • Click the name of the node to view its details. For more information, see Node details.
  • Move the pointer over the curve of a metric to view the specific statistic at the specified point in time.

API operation details

In the details panel of an API operation, you can view the following information about each request to the API operation: the time when the request is sent, amount of time consumed, HTTP status code, and relevant trace ID.

Container monitoring - Container details - API operation details

In the API operation details panel, you can perform the following operations:

Click View details in the Operation column of a request to view the following information about the request: request URL, request headers, request body, response headers, response body, HTTP status code returned, call typology, and the result, amount of time consumed, and speed of each phase.
