The Cluster Overview and Overview pages on OCP show the status monitoring information of OceanBase clusters.
Prerequisites
Before you log on, make sure that you have the read-only permissions or management permissions on the cluster. Otherwise, you cannot view the overview data of the cluster.
Background
The operation interface of OCP may vary with the version. The following describes how to view status monitoring information of OceanBase clusters on OCP V2.4.4. For operations on other OCP versions, see the OCP User Guide of the corresponding version.
In OCP V2.3.0, status monitoring information of OceanBase clusters is displayed on the dashboard.
Procedure
Log on to the OCP console. The Cluster Overview page automatically appears.
The Cluster Overview page shows all the OceanBase clusters of the user.
View the following cluster status information:
Top 5 Clusters by Elapsed Time of Major Freeze
Displays a bar chart of five clusters with longest major compaction time in the last three days. A major compaction compacts all dynamic and static data, which is time-consuming. When the incremental data generated through minor compactions reaches the specified threshold, OceanBase Database performs a major compaction of data of the same major version.
Displays no information if no major compaction has been carried out for clusters in the last three days.
Server Resources
Displays the total number of servers in each IDC and the number of servers where OBServer has been deployed.
Resource Usage
Displays the cluster name, host role (primary/secondary), number of tenants, and total resource units and allocated resource units of each cluster, including the allocated CPU percentage, allocated memory percentage, occupied disk space, and total disk space.
Clusters
Displays the name, ID, version, deployment mode (including the region of each zone and number of OBServers), status, creation time, and alert statistics of each cluster.
By default, for a primary/secondary database, only information about the primary cluster is displayed. You can click the + icon on the left to view information about the secondary cluster.
In the Clusters area, click the name of a cluster. The Overview page of the cluster appears.
The Cluster Overview page shows the following status information of the specified OceanBase cluster:Cluster Overview
Displays the cluster type, OceanBase Database version, number of regions, number of zones, number of servers, number of partitions, number of tenants, cluster creator, and Config URL of the current cluster.
Resource Usage
Displays the percentage of available system resources in the cluster, including the CPU, memory, and disk resources.
Alert Overview
Displays all alerts related to the current cluster by severity.
The alerts are categorized into five levels by severity: stopped, critical, warning, caution, and reminder.
By default, the system displays all existing alerts. You can filter the alerts of the last 24 hours, last week, or last 30 days as required.
System Events in Last 7 Days
Displays details about RootService-related events of the current cluster in order of the event occurrence time.
The information displayed for each system event includes the event name, module, start time, details, and description.
For common events, the system displays the event details and description. For uncommon events, no information is provided for the event details and description.
Zones
Displays basic information about each zone in the current cluster, including the zone name, region, IDC, RootServer address, and status. The list also provides an entry to zone-level O&M operations, including adding an OBServer, restarting OBServer processes on all nodes in a zone, stopping OBServer processes on all nodes in a zone, and deleting all nodes in a zone.
OBServers
Displays basic information about each OBServer in the current cluster, including the IP address, OBServer port, IDC, zone, host type, and the remaining CPU, memory, and disk resources.
OCP also provides an entry to common OBServer O&M operations for the current cluster, including restarting, starting, stopping, replacing, and deleting OBServers.
