Parameter |
Description |
|---|---|
| Cluster Name | The name of the cluster. Click the copy button on the right to copy the cluster name. |
| Cluster ID | The unique cluster identifier automatically generated when the cluster is created. |
| Cluster Type | Displays the type of the current cluster, which can be Primary Cluster or Standby Cluster. This parameter is displayed only for OceanBase Database versions earlier than V4.0. |
| OceanBase version number | The version number of the OceanBase database in the current cluster. |
| Number of Regions | The number of regions in the current cluster. |
| Deployment Mode | The deployment mode of the current cluster. |
| CPU Architecture | When adding a host, OCP automatically identifies the host's hardware architecture. If the cluster contains multiple different hardware architectures, all architecture information is displayed. |
| Cgroup Configuration | Displays whether Cgroup is enabled for the current cluster. Click Edit to disable or enable it.
Note
|
| CPU Overcommitment | This parameter is displayed only for OceanBase Database V4.0 and later. It indicates whether CPU overprovisioning is enabled for the current cluster. Click Edit to disable or enable it.
NoteThe CPU overprovisioning feature depends on Cgroup. Before configuring the CPU overprovisioning ratio, please enable Cgroup for the cluster. |
| Number of Machines | The number of hosts in the current cluster. |
| Load Type | The load type of the current cluster. Click Edit to change the load type. |
| Number of Partitions | Displays the number of partitions for tables in the current cluster. |
| Number of Tenants | The number of tenants in the current cluster. |
| Created By | The username of the user who created the current cluster. |
| Startup Time | The last start time of the cluster. |
| Online Duration | The duration since the cluster was last started. |
| OBProxy Cluster | Displays the OBProxy cluster associated with the current OceanBase cluster. |
| Protection Mode | This field is displayed only for OceanBase clusters of versions earlier than V4.0 and when the cluster type is Primary Cluster. It shows the protection mode of the current cluster. For more information, see Protection Mode. |
| Software Installation Path | Displays the path specified when creating the cluster. |
| JVM Environment Dependency Service | Only displayed for OceanBase Database V4.3.5.1 and later, this section shows the specific status of the JVM environment dependency services configured for the current cluster. You can enable, edit, or disable JVM environment dependency services. For specific configuration requirements and descriptions, see Configure JVM environment dependency services in Create a distributed cluster or Create a standalone centralized cluster.
NoticeEnabling, disabling, modifying the service type, or adjusting the memory configuration of a JVM environment dependency service will cause the cluster to restart. This may interrupt access to all businesses that depend on this cluster. Evaluate the potential impact thoroughly before proceeding. |
| Data Disk Path | Displays the path specified when creating the cluster. |
| Cache Disk Path | This field is displayed only for AI clusters with shared storage and shows the cache disk path specified during cluster creation. In shared storage mode, local disks are used only for caching. |
| Object Storage Type | Displays only for AI clusters (in shared storage mode), showing the object storage type used by the cluster, such as S3, OSS, COS, OBS, etc. |
| Bucket URI | Displays only for AI clusters (with shared storage), showing the object storage bucket URI used by the cluster. |
| ConfigUrl | The URL of the current cluster. You can click the copy icon to copy the ConfigUrl. |
| Tag | A label set based on the cluster content and attributes. Hover your cursor over a cluster label to view all its tag information. You can click the edit icon to manage tags. For more information, see Manage tags. |
View resource utilization
In the resource utilization section, you can view the current cluster's CPU, Memory, and Data Disk Used. You can manage the cluster based on its current resource utilization.
Note
View alert overview
In the alert overview section, you can view alerts for the current cluster, including different types of alerts: Cluster Alerts, Tenant Alerts, OBServer Alerts, and Log Alerts.
View system events from the last 7 days
In System Events in Last 7 Days, you can set query conditions as needed to view system events from the past seven days.
You can set the search time at position ① in the figure.
You can set the event name to search for at position ② in the figure.
You can set the module to search for at position ③ in the figure.
You can sort events in ascending or descending order by start time at position ④ in the figure.
The system will display the system events you want to view in the list based on the conditions you have set.
View the zone list
In the zone list, you can search for and view the Zone Name, Region, IDC, Servers, Root Service, Software Package Type, CPU Architecture, and Status of each zone. You can also perform operations such as Add OBServer, Edit, Restart, Stop, and Delete on a zone. For more information, see Add an OBServer node, Edit a zone, Restart a zone, Stop a zone, and Delete a zone.
View the OBServer list
In the OBServer list, you can view information about each OBServer node, including IP Address, SQL Port, RPC Port, Zone, Host Type, Start Time, Online Duration, Resource Usage (CPU, Memory, Log Disk, Data Disk), and Status.
When an OBServer node is unavailable, hover your cursor over the unavailable icon to view the duration, cause, and suggested solution for its unavailability.
You can perform operations such as Restart, Stop Service, Stop Process, Reinstall, Replace, Delete, and Download Logs on an OBServer node. For more information, see Restart an OBServer node, Stop an OBServer service, Stop an OBServer process, Reinstall an OBServer node, Replace an OBServer node, Delete an OBServer node, and Download logs.
Note
View the arbitration service list
In the arbitration service list, you can view the Service Group, Service Address, Connection Status, Priority, Tenant Enabling the Service, Automatic Execution, and Added At. Click the Service Address to go to the arbitration service management page. On this page, you can perform operations such as Add Arbitration Service, Add Service Group, Replace Service, and Remove Service. For details, see Add an arbitration service, Add a service group, Replace a service, and Remove a service.
Protection Modes
Note
The protection mode applies only to traditional clusters (in shared-nothing mode). AI clusters (in shared-storage mode) do not support primary/standby architecture.
Maximum Performance: Ensures maximum performance of the primary cluster while protecting user data. In this mode, log transmission between all standby clusters and the primary cluster is asynchronous.
Maximum Availability Mode: Normally, one and only one standby cluster maintains synchronous log transmission with the primary cluster.
Maximum Protection Mode: One and only one standby cluster maintains synchronous log transmission with the primary cluster; other standby clusters use asynchronous log transmission.
