How to view cluster status - Elasticsearch - Alibaba Cloud Documentation Center

You can use the node visualization and node information features of an Alibaba Cloud ES instance to view the status of an ES cluster and basic node information, such as IP addresses, statuses, CPU usage, memory size, disk usage, and JVM memory. This topic describes how to view the cluster status and node information.

Go to the node visualization area

Log on to the Alibaba Cloud Elasticsearch console.
In the left-side navigation pane, click Elasticsearch Clusters.
Navigate to the desired cluster.
1. In the top navigation bar, select the resource group to which the cluster belongs and the region where the cluster resides.
2. On the Elasticsearch Clusters page, find the cluster and click its ID.
Find the Node Visualization area at the bottom of the Basic Information page.

View cluster health status

Alibaba Cloud ES provides two ways to view the health status of your cluster:

Console visualization
The health status of the cluster is displayed in the Node Visualization area on the Basic Information page. To view the status:
1. Go to the node visualization area.
2. Hover over the Cluster icon. In the dialog box that appears, view the cluster Status.
  To obtain a cluster health diagnostic report, click Artificial Intelligence for IT Operations.
  Note
  The retrieval of cluster and node status may be delayed. During an instance change, the displayed status may not reflect the real-time status. The preceding figure shows the health status information when the cluster is stable.
Command
You can also use the Health API to view the cluster health status.
```
GET /_cluster/health
```

View basic node information

Go to the node visualization area.
Check the color of each node in the cluster to determine its health status.
Note
Alibaba Cloud uses colors to indicate node health based on usage thresholds. These colors correspond to the metrics in CloudMonitor. For more information, see Metric description and suggestions for handling exceptions.
- Red: Warning status.
- Yellow: Alert status.
- Green: Normal status.
- Gray: Unknown status (information has not been retrieved for a long time).
Hover over a node. In the dialog box that appears, you can view the information about the node.
Note
- If the Node Status is red, yellow, or gray, the system displays a message. The message may read Node Is Disconnected. We Recommend That You Use AIOps For Diagnosis. or Node Is In Poor Health. We Recommend That You Use AIOps For Diagnosis.. You can click AIOps Diagnosis to navigate to the Intelligent O&M > Cluster Diagnostics page to diagnose the cluster.
- Click Restart. In the Restart dialog box, you can restart the cluster or node.

View node configuration information

Go to the node visualization area.
Click the icon in the upper-right corner. In the configuration list, you can view the configuration information of the nodes.
For more information about the configurations, see ES instance node configurations.
