Procedure for Using Logstash

**Table 1** Procedure for using a Logstash cluster
Category	Operation		Details
Use	Planning a cluster	Before creating a Logstash cluster, develop a plan for it, such as whether to deploy the cluster across multiple AZs to improve availability; and the node quantity and specifications in order to ensure the desired performance and reliability.	Logstash Cluster Planning Suggestions
	Creating a cluster	Create a Logstash cluster based on the plan.	Creating a Logstash Cluster
	Configuring routes	If the Logstash cluster and the data source are connected to the same primary NIC, the network is automatically connected. Otherwise, you need to configure routes connecting each node of the Logstash cluster to the data source and back.	Configuring Routes for a Logstash Cluster
	Configuring a Logstash migration task	Through the configuration center of the Logstash cluster, you can create and start a Logstash configuration file to migrate data between different locations.	Creating a Logstash Configuration File Starting a Logstash Migration Task
O&M	Scaling a cluster	CSS provides flexible scale-out and scale-in options, using which you can add or reduce nodes, and increase or reduce node specifications. This allows you to dynamically adjust cluster resources to meet changing demand and optimize costs.	Scaling Out a Logstash Cluster Scaling In a Logstash Cluster
	Managing clusters	CSS provides comprehensive cluster management functions. Users can view cluster information, manage tags, bind clusters with enterprise projects, and upload custom CA certificates. They help users efficiently manage Logstash clusters.

	Monitoring and log management	CSS provides comprehensive monitoring and log management. Users can configure and check monitoring metrics for clusters, nodes, and Logstash pipelines, configure alarm rules, and back up and view logs. They help users efficiently monitor and analyze the performance of Logstash clusters, ensuring cluster reliability.
