Viewing Logstash Cluster Information

On the CSS management console, you can check a Logstash cluster's status, version, nodes, configurations and settings, and resource allocation on both the cluster list and the cluster overview page.

Introduction to the Cluster List

A cluster list displays all clusters of the same type under the current account. If there are a large number of clusters, the cluster list will consist of multiple pages, showing clusters of all states.

Clusters are listed in chronological order by default in the cluster list, with the most recent clusters displayed at the top.

You can click Export to download the full cluster list.

**Table 1** Cluster list parameters
Parameter	Description
Name/ID	Name and ID of a cluster. The cluster ID is automatically generated by the system and uniquely identifies a cluster.
Cluster Status	Current status of a cluster. Available: The cluster is running properly. Creating: The cluster is being created. Processing: The cluster is being restarted, scaled out, scaled in, or its node specifications are being changed. Abnormal: The cluster failed to be created or is unavailable. WARNING: A cluster that is unavailable can be deleted, but cannot be scaled out. For such a cluster, you can check its monitoring data or restart it to try to fix the problem. If the fault persists, contact technical support.
Task Status	The status of tasks such as cluster restarting, scaling out, and scaling in, or ongoing pipeline tasks.
Version	Cluster version and image version. For example, if the version is 7.10.0(7.10.0_x.x.x_x.x.x), 7.10.0 is the cluster version and 7.10.0_x.x.x_x.x.x enclosed in parentheses is the image version. CAUTION: For a cluster created a long time ago, its image version may not be available because it is likely not recorded in the database.
Private Network Address	Private network address and port number of a cluster. You can use it to access the cluster. If the cluster has multiple nodes, the private network addresses and port numbers of all nodes are displayed.
Enterprise Project	Enterprise project that a cluster belongs to.
Tags	Displays cluster tags. You can click Edit Tag to add, delete, or modify cluster tags.
Cluster Description	Provides supplementary information about the cluster.
Created	Cluster creation time.
Billing Mode	Billing mode of a cluster. It can be Pay-per-use or Yearly/Monthly.
Operation	Operations that can be performed on a cluster, such as checking metrics, restart, and deletion. If an operation is unavailable, the menu button is grayed out.

Viewing Basic Cluster Information

Log in to the CSS management console.
In the navigation pane on the left, choose Clusters > Logstash.
In the cluster list, click the name of the target cluster. The cluster information page is displayed.

On the Overview tab, check the cluster's basic information, node configuration, and network information.

**Table 2** Basic cluster information
Parameter	Description
Cluster ID	Unique ID of a cluster, which is automatically generated by the system. Each cluster ID is unique within the same region.
Cluster Name	Cluster name. You can click to change the cluster name.
Cluster Version	Cluster version. For example, if the version is 7.10.0(7.10.0_x.x.x_x.x.x), 7.10.0 is the cluster version and 7.10.0_x.x.x_x.x.x enclosed in parentheses is the image version. CAUTION: For a cluster created a long time ago, its image version may not be available because it is likely not recorded in the database.
Cluster Status	Current status of a cluster
Task Status	Current task status of a cluster. If there is no ongoing task, -- is displayed.
Region \| AZ	The region and AZ where the cluster is located.
Enterprise Project	Enterprise project that a cluster belongs to. You can click a project name to check the basic project information.
Cluster Description	Provides supplementary information about the cluster. You can click to modify the description.

**Table 3** Node information
Parameter	Description
Logstash Node Specifications	Specifications of nodes in a Logstash cluster
Logstash Nodes	Number of nodes in a Logstash cluster
Logstash Node Storage Type	The storage type of Logstash nodes in the cluster.
Logstash Node Capacity (GB)	Storage capacity per node in the cluster.
Cluster Storage Capacity (GB)	Total storage capacity of the cluster. Quota: the upper limit of the storage capacity allocated to the cluster. Used: storage space already used by the cluster. The cluster's disk usage can be calculated as follows: Disk usage = (Used/Quota) x 100%
Node Details	View the details of all cluster nodes. Click View. In the displayed dialog box, view node details, including the node name/ID, status, and IP address.

**Table 4** Network information
Parameter	Description
VPC	VPC to which a cluster belongs
Subnet	Subnet to which the cluster belongs
Security Group	Security group to which a cluster belongs. To modify the security group of a cluster, click Change Security Group. WARNING: The selected security group must allow port 9600 in the inbound direction. Otherwise, the cluster may be inaccessible to external services.
Private IPv4 Address	Private IPv4 address and port number of a cluster. If the cluster has only one node, the IP address and port number of only one node are displayed, for example, 10.62.179.32:9600. If the cluster has multiple nodes, the IP addresses and port numbers of all nodes are displayed, for example, 10.62.179.32:9600,10.62.179.33:9600.
Cluster Route	Cluster route information. You can view, add, or modify cluster routes. For details, see Configuring Routes for a Logstash Cluster.

**Table 5** Additional information
Parameter	Description
Billing Mode	Billing mode of a cluster, which can be pay-per-use or yearly/monthly.
Last Transaction Order	Latest order of the yearly/monthly subscription. You can click an order number to go to the Billing Center and view order details. This parameter is displayed only when Billing Mode is Yearly/Monthly.
Created	When a cluster was successfully created.
Expires At	When a yearly/monthly cluster will expire. This parameter is displayed only when Billing Mode is Yearly/Monthly.
Upon Expiration	What will happen when a yearly/monthly subscription expires, for example, automatic renewal or changing to pay-per-use. This parameter is displayed only when Billing Mode is Yearly/Monthly.
