| Cluster Name | The name of the cluster. You can click the right-side Copy icon to copy the cluster name. |
| Cluster ID | The automatically generated unique ID of the cluster. |
| Cluster Type | The type of the cluster. The value can be Primary Cluster or Standby Cluster.
NoteThe Cluster Type field is not displayed for a cluster of V4.0 and later. |
| OceanBase Version | The version of OceanBase Database of the cluster. |
| Number of Regions | The number of regions of the cluster. |
| Deployment Mode | The deployment mode of the cluster. |
| CPU Architecture | The hardware architecture of the host. OCP automatically identifies the hardware architecture of the host when you add the host. If multiple hardware architectures are used in the cluster, all hardware architectures are displayed. |
| Cgroup Configuration | Indicates whether Cgroup is enabled for the cluster. You can click Edit to enable or disable Cgroup.
Note
|
| CPU Overcommit Quota | Indicates whether CPU overcommit is enabled for the cluster. You can click Edit to enable or disable CPU overcommit.
Note
|
| Number of Hosts | The number of hosts in the cluster. |
| Load Type | The load type of the cluster. You can click Edit to change the load type. |
| Number of Partitions | The number of partitions of the table.
NoteThe Number of Partitions field is not displayed for a cluster of V4.0 and later. |
| Number of Tenants | The number of tenants in the cluster. |
| Creator | The name of the user who created the cluster. |
| Startup Time | The time when the cluster was last started. |
| Online Duration | The time that the cluster has been online since the current startup. |
| OBProxy Cluster | The OBProxy cluster associated with the OceanBase cluster. |
| Protection Mode | The protection mode of the cluster. This field is displayed only when the cluster type is Primary Cluster. For more information, see Protection Mode.
NoteThe Protection Mode field is not displayed for a cluster of V4.0 and later. |
| Software Installation Path | The path specified when the cluster was created. |
| Data Disk Path | The path specified when the cluster was created. |
| Log Disk Path | The path specified when the cluster was created. |
| Log Transmission Mode | The log transmission mode of the cluster. This field is displayed only when the cluster type is Standby Cluster. The value can be Synchronous or Asynchronous. If the transmission mode is Synchronous, the Synchronization Status field can be Asynchronous, which is related to the Protection Mode. |
| Synchronization Status | The log transmission latency of the cluster. This field is displayed only when the cluster type is Standby Cluster. |
| ConfigUrl | The URL of the cluster. You can click the Copy icon to copy the ConfigUrl. |
| Tag | The identifier set based on the content and attributes of the cluster. Hover the pointer over the cluster tag to view all the tag information of the cluster. You can click the Edit icon to manage the tags. For more information, see Manage tags. |
View resource usage
In the resource usage section, you can view the Allocated CPU, Allocated Memory, Allocated Log Disk, and Data Disk Used of the current cluster. You can also manage the cluster based on the resource usage.
Note
View an alert overview
In the alert overview section, you can view alerts of the current cluster, including: Cluster Alert, Tenant Alerts, OBServer Alerts, and Log Alerts.
View system events in the last 7 days
In the System Events in Last 7 Days section, you can set the query conditions as needed to view system events in the last seven days.
The system will display the system events you want to view based on the settings.
View the list of zones
You can search for and view the Zone Name, Region, IDC, Servers, Root Service, CPU Architecture, and Status of zones in the list. You can also Add OBServer, Edit, Restart, Stop, and Delete 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 list of OBServer nodes
You can view the information about IP address, SQL port, RPC port, zone, host type, startup time, online duration, resource usage (CPU, memory, log disk, and data disk), and Status of OBServer nodes in the list.
When an OBServer node is unavailable, hover the pointer over the icon to view the duration of unavailability, cause, and solution.
You can perform the following operations on an OBServer node: reboot, stop service, stop process, reinstall, replace, delete, and Download Logs. For more information, see Reboot 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 list of arbitration services
You can view the information about service group, service address, connection status, priority, tenant that enables the service, automatic execution, and Added At of arbitration services in the list. You can click Service Address to view the arbitration service management page. You can also perform the following operations on an arbitration service: add arbitration service, add service group, replace service, and remove service. For more information, see Add an arbitration service, Add a service group, Replace an arbitration service, and Remove an arbitration service.
Manage a cluster
On the cluster overview page, you can also perform basic cluster management operations. For more information, see Add an OBServer node, Create a zone, Create a tenant, Create a standby cluster, Upgrade the cluster version, Change the password of the sys tenant, Restart the cluster, Stop the cluster, Delete a cluster, Decouple the primary and standby databases, Enable automatic deadlock detection, Disable automatic deadlock detection, Manage CPU core binding configurations, Manage O&M configurations, and Download logs.
You can also perform routine O&M operations on a cluster based on the left-side navigation pane. For more information, see View the topology of a cluster, Manage tenants, View performance metrics, View performance reports, Manage cluster resources, Merge clusters, Backup and restore clusters, and Manage cluster parameters.
Protection mode
Maximum performance: Ensures the maximum performance of the primary cluster while protecting your data. In this mode, logs are asynchronously transmitted to all standby clusters and the primary cluster.
Maximum availability: In normal operation, only one standby cluster is in sync with the primary cluster for log transmission.
Maximum protection: In normal operation, only one standby cluster is in sync with the primary cluster for log transmission, and other standby clusters use asynchronous log transmission.
Switch clusters
To view the overview information of another cluster, click the name of the cluster in the upper-left corner of the Overview page. The current overview page will then switch to the overview page of the cluster you want to view.
