On the page that is displayed, you can view the cluster status, real-time resource consumption, top SQL statements, cluster resource consumption, and key database metrics.
In the Cluster Status area, you can view the status of the current cluster and the number of available resources, including the numbers of nodes, CNs, and databases.
In Resource Consumption, you can view the real-time resource consumption of the current cluster, including Memory Usage, Disk Usage, CPU Usage, Disk I/O (KB/s), and Network I/O (KB/s).
In the TOP SQL area, you can query the SQL statements that take the longest time and have the largest amount of data flushed to disks in the current cluster.
Top 5 SQL statement query is implemented by max_ctime, which displays the query duration and the amount of data written to disks in the current collection period. If no query is executed during off-peak hours, the top 5 time-consuming query page will not be refreshed.
On the Cluster Overview page, you can also view the database metrics of the current cluster, including Sessions and Queries.
