Viewing the Replication Latency and Traffic of a RegionlessDB Cluster

Method 1: Viewing Metrics on the Console

1. Log in to the management console.
2. Click in the upper left corner and select the region and project of the primary instance.
3. Click and select Cloud Eye under Management & Governance.
4. In the navigation pane, choose Cloud Service Monitoring > GaussDB(for MySQL).
5. Click in the front of a RegionlessDB cluster. Locate a standby instance and click View Metric in the Operation column.
   • Cloud Eye can monitor performance metrics in the last 1 hour, last 3 hours, last 12 hours, last 24 hours or last 7 days.

   • For details about metrics supported by RegionlessDB clusters, see Table 1.

     Table 1 RegionlessDB cluster metrics

     Metric ID	Metric Name	Description	Value Range	Monitored Object	Monitoring Interval (Raw Data)
     gdb_replication_latency	GDB Replication Delay	Data replication latency of the measured object	≥0 ms	RegionlessDB standby instances	1 minute
     gdb_replication_capacity	GDB Replication Traffic	Data replication traffic of the measured object	≥0 bytes/s	RegionlessDB standby instances	1 minute

     

     For details about the metrics of primary and standby instances, see section 4.17.3

Method 2: Viewing Metrics Using SQL Commands

Use a MySQL client tool to connect to the GaussDB(for MySQL) instance and run the following command to query the RegionlessDB status:

mysql> select * from information_schema.global_db_status;

Figure 2 Querying the RegionlessDB status

In the command output, each row indicates an instance in the RegionlessDB cluster (the first row indicates the primary instance and other rows indicate the standby instances). For details about the parameters contained in each row, see Table 2.
