View node details

A distributed system is a system of multiple nodes that are physically separated but linked together using the network. A node is an entity capable of independent communication within the network, such as a server, router, or computer. Each node possesses a unique IP address and can interact with other nodes. Serverless App Engine (SAE) provides the node details feature. You can use this feature to view the details of all nodes of an application. The node details include the basic information, node-level queries per second (QPS) metrics, operating system metrics, and traffic monitoring metrics of node interfaces. This topic describes how to view the details of a node.

Prerequisites

An application is created.
Microservices Governance is activated.
Note
Using Microservices Engine (MSE) incurs fees. See Billing overview of Microservices Governance for more details.

Limits

This applies to microservice applications created on or after November 8, 2023.

Procedure

Log on to the SAE console. In the left-side navigation pane, choose Applications > Applications. On the page that appears, select a region in the top navigation bar and a namespace from the Namespace drop-down list, and then click the desired application name.
In the left-side navigation pane, choose Microservice Governance > Node Details.

Feature

View the basic information about a node

1: Allows you to search for nodes by IP address or name.
2: Displays nodes by Node IP Address or Node Name.
3: Sorts nodes based on Requests, Reject Quantity, Abnormal Requests, or RT in the latest 5 minutes.
4: Displays the basic information about a node.
- The basic information includes Node Name, Zone, IP address, Process ID, Probe Version, Label, Start Time, and Microservice status.
- You can manually start or shut down a node by clicking the related option in the Actions column.
5: Displays metric data on the Node Overview and Interface details tabs based on the playback time that you selected.
Note
Metric data within 24 hours can be played back. Only metric data of the current online nodes can be played back.

Basic Information tab: displays the basic information about the node. The display content and style of this tab are the same as those of the Node Overview tab.
Node Overview tab: displays the QPS data, RT data, and CPU metrics.
Interface details tab: displays the metrics of different interfaces of the node.
