View details of a host

On the details page of a host, you can view basic information, OceanBase Cloud Platform (OCP) Agent information, and monitoring data of the host.

Prerequisites

Make sure that you have the following permissions:

• Resource Permissions : Cluster Read-only, Tenant Read-only, or Host Read-only permission
• Menu Permissions : Menu Permissions : Permission on the All menu of Hosts

View basic information of a host

On the Basic Information tab of the host, you can view the details and disk usage information of the host, and manage tags.

• In the Details section, you can view the status, name, alias, SSH port number, IDC, type, category, region, disk usage, service, clock offset, current time, time zone, operating system, CPU architecture, CPU model, number of CPU cores, tags, total memory size, and description of the host.

  You can hover the pointer over the Tag field of the host to view all its tags, and then click the Edit icon to manage the tags. For more information, see Manage tags.

• In the Disk Usage section, you can view disk path information such as the total size of the disk partition, used size of the disk partition, available size of the disk partition, disk partition usage, and mounted directory.

View OCP Agent information

On the OCP Agent tab, you can view information about OCP Agent in the View Details and Processes sections.

• The View Details section displays the status, installation directory, installation time, version, log directory, and future available periods of OCP Agent.

• The Processes section displays the details of processes, such as the ID, name, startup command, operating system user, port number, specification, uptime, future available periods, and status of processes.

  • Click Download Logs in the Actions column of a process to download its logs.

  • Click Change Specification in the Actions column of the ocp_monagent process to adjust the specification of OCP Agent for the host.

    Notice

  • We recommend that you set the specification to no greater than 6 cores and 12 GiB of memory.
  • We recommend that the memory specified for the `ocp_monagent` process be lower than the available physical memory size of each host in the cluster. Otherwise, the configuration may fail. To view the memory usage of a host, choose Performance Monitoring > Host Performance > Host Dimension > Memory.
  • The specification change takes effect after OCP Agent restarts. During the restart, OCP cannot perform O&M operations, and some monitoring data will be lost. Proceed with caution. For more information, see Restart OCP Agent.
  • For information about how to adjust the resource specification of OCP Agent for all hosts in a cluster, see Configure resources for OCP Agent.

View monitoring data

On the Monitoring tab, you can view host monitoring data on the Host Performance, Host Resources and Host Processes tabs. For more information, see View host performance, View host resources, and View host processes.
