When you run microservices in production, you need instance-level visibility to detect degraded nodes, diagnose latency spikes, and verify that new deployments handle traffic correctly. The node details page in Microservices Governance shows health status, queries per second (QPS), response time (RT), operating system metrics, and per-interface traffic for every node in an application.
Prerequisites
Before you begin, make sure that you have:
Microservices Governance of Microservices Engine (MSE) enabled for your application. For instructions, see Connect microservice applications deployed in an ACK cluster to Microservices Governance
Open the node details page
Log on to the MSE console.
In the top navigation bar, select a region.
In the left-side navigation pane, choose Microservices Governance > Application Governance.
On the Application list page, click the resource card of your application.
In the left-side navigation pane, click Node details.
Node list
The node list gives you a high-level view of all nodes in the application. Search, sort, and select individual nodes for deeper inspection.
Search and display
Search: Find nodes by IP address or name.
Display mode: Switch between Node IP Address and Node Name to control how nodes appear in the list.
Sort nodes
Sort nodes by the following metrics. Values are calculated from the most recent 5 minutes of data.
| Sort option | Description |
|---|---|
| Requests | Total request count |
| Reject Quantity | Number of rejected requests |
| Abnormal Requests | Number of requests that returned errors |
| RT | Average response time |
Node fields
Each node card displays the following information:
| Field | Description |
|---|---|
| Node Name | Name assigned to the node |
| Zone | Availability zone where the node runs |
| IP address | Network address of the node |
| Process ID | Operating system process identifier |
| Probe Version | Version of the MSE governance agent installed on the node |
| Label | Custom tags attached to the node |
| Start Time | Timestamp when the node started |
| Microservice status | Current registration and health state of the node |
In the Actions column, you can manually start or shut down a node.
Metric playback
Select a playback time to view historical metric data on the Node Overview and Interface details tabs.
Playback covers up to 24 hours of history and is available only for nodes that are currently online.
Inspect a specific node
On the Node details page, locate the node in the All Nodes section.
Click the node card.
The detail view contains three tabs:
| Tab | Description |
|---|---|
| Basic Information | Node metadata, displayed in the same content and style as the Node Overview tab |
| Node Overview | QPS trends, RT distribution, and CPU utilization over time |
| Interface details | Per-interface metrics for individual service endpoints on the node |
Troubleshoot a node issue
Use node details to trace a performance problem from a high-level anomaly down to the specific interface causing it.
Spot the anomaly -- On the node list, sort by Abnormal Requests or RT to surface nodes with elevated error rates or latency.
Inspect the node -- Click the problem node and open the Node Overview tab to check whether QPS, RT, or CPU spiked at the same time.
Drill into interfaces -- Switch to the Interface details tab to identify which interface is generating errors or high latency.
Correlate with changes -- Check Start Time and Probe Version on the Basic Information tab to determine whether a recent deployment or agent upgrade coincides with the issue.
