Enable the X-Pack Monitoring feature - Logstash| Alibaba Cloud Documentation Center

This topic describes how to enable the X-Pack Monitoring feature. This feature helps monitor your Alibaba Cloud Logstash cluster. After you enable the feature for your Logstash cluster and associate the cluster with an Elasticsearch cluster, you can monitor the Logstash cluster in the Kibana console of the Elasticsearch cluster.

Prerequisites

An Alibaba Cloud Logstash cluster is created. For more information, see Create a cluster.
An Alibaba Cloud Elasticsearch cluster is created. The Elasticsearch cluster must meet the following requirements:
- The Elasticsearch cluster resides in the same virtual private cloud (VPC) as the Logstash cluster. We recommend that you create an Elasticsearch cluster that uses the same major version as the Logstash cluster. If the Elasticsearch cluster uses a major version that is different from the major version of the Logstash cluster, make sure that the version of the Elasticsearch cluster is compatible with the version of the Logstash cluster. For more information, see Create an Alibaba Cloud Elasticsearch cluster.
- The Public Network Access feature is enabled on the Kibana Configuration page of the Elasticsearch cluster. For more information, see Configure an IP address whitelist for access to the Kibana console over the Internet or an internal network.

Procedure

Log on to the Elasticsearch console.
In the left-side navigation pane of the page that appears, click Cluster Monitoring.
In the Monitoring and Alerting section, click Edit on the right side of X-Pack Monitoring.

In the Edit Configuration panel, set X-Pack Monitoring to Enable and associate the Logstash cluster with your Elasticsearch cluster.


Parameter	Description
Elasticsearch Cluster	Select the Elasticsearch cluster with which you want to associate the Logstash cluster. You must select an Elasticsearch cluster that resides in the same VPC as the Logstash cluster. We recommend that you select an Elasticsearch cluster that uses the same major version as the Logstash cluster. If the Elasticsearch cluster uses a major version that is different from the major version of the Logstash cluster, make sure that the version of the Elasticsearch cluster is compatible with the version of the Logstash cluster.
Username	Enter the username that is used to access the Elasticsearch cluster.
Password	Enter the password that is used to access the Elasticsearch cluster.

Click Test Connectivity.
If no error is reported, the Elasticsearch cluster is connected.

Warning After you enable or disable X-Pack Monitoring, the system restarts the Logstash cluster. This may affect your services. Proceed with caution.
Click OK.
The system returns to the Cluster Monitoring page and restarts the Logstash cluster.
After the Logstash cluster is restarted, view the monitoring data of the Logstash cluster.
After the Logstash cluster is restarted, the value of X-Pack Monitoring changes to Enable, and the associated Elasticsearch cluster appears.

Notice You can view the monitoring data of the Logstash cluster in the Kibana console only after the Logstash cluster is restarted.
1. On the Cluster Monitoring page, click Kibana Console on the right side of Connect to Elasticsearch Cluster.
2. Log on to the Kibana console of the associated Elasticsearch cluster.
  For more information, see Log on to the Kibana console.
3. In the left-side navigation pane, click Monitoring.
4. In the Logstash section, view the monitoring data of the Logstash cluster.
