This topic describes how to view the details of a container in the Application Real-Time Monitoring Service (ARMS) console.
Procedure
Basic information
In the basic information section, you can view the following information about the container: the number of requests, number of errors, average response time, number of slow calls, number of limited CPU cores, number of failed memory allocation requests, and running duration.
- 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
Kubernetes 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 the metrics that are related to the protocol. For more information, see Protocol-related metrics.
CPU and memory
In the CPU section, you can view the time series curves of the following metrics: CPU utilization, number of requested CPU cores, number of limited CPU cores. In the Memory section, you can view the time series curves of the following metrics: memory usage, amount of requested memory, and amount of limited 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 statistics at a specific 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 data that is generated because the CPU usage of the container is throttled, for example, the current CPU utilization exceeds the upper limit.
In the Memory FailCnt section, you can view the number of failed memory allocation requests. For example, a memory allocation request may fail because the current memory usage exceeds the upper limit.
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 statistics at a specific point in time.
Node
In the Node section, you can view the time series curves of the following metrics about the node that hosts the container: node name, CPU utilization, memory usage, disk usage, and network traffic.
- 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 statistics at a specific point in time.
