This topic describes how to monitor the performance of hosts in a cluster by using OceanBase Cloud.
Procedure
Log in to the OceanBase Cloud console.
In the left-side navigation pane, click Instances.
On the Instances page, click the name of the target instance to go to the Overview page of the instance.
In the left-side navigation pane of the Overview page of the instance, click Metrics.
On the Metrics page, click the Host Metrics tab.
By default, this tab shows the monitoring data of all nodes in the cluster in the last 6 hours.
- You can select a node from the Node drop-down list to view its monitoring data. If you select multiple nodes, you can click node names in a chart to filter the data to view.
- You can also specify a time period to filter the data to view.
The following table describes the performance metrics.
Monitoring item Metric Unit Description Load load1 % The average CPU load in the last 1 minute CPU Usage cpu_percent % The CPU utilization Memory memory_used % The size of physical memory used by the node Network Throughput net_throughput MB The network throughput NTP Offset ntp_offset_milliseconds ms The NTP clock offset OB Data Disk Usage ob_data_disk_percent % The data disk usage of the node OB Log Disk Usage ob_clog_disk_percent % The log disk usage of the node Disk Usage ob_data_disk_used_size GB The data disk space used by the node OB Process Status ob_process_exists - The status of the OB process OB Log Disk IOPS ob_clog_io times/s The average number of I/O operations per second on the log disk OB Log Disk IO Time ob_clog_io_time ms The average time spent on each I/O operation on the log disk OB Log Disk IO Throughput ob_clog_io_byte MB The average I/O throughput per second of the log disk OB Log Disk IO Utilization ob_clog_io_util % The I/O usage of the log disk OB Data Disk IOPS ob_data_io times/s The average number of I/O operations per second on the data disk OB Data Disk IO Time ob_data_io_time ms The average time spent on each I/O operation on the data disk OB Data Disk IO Throughput ob_data_io_byte MB The average I/O throughput per second of the data disk OB Data Disk IO Utilization ob_data_io_util % The I/O usage of the data disk
