Is the server down? when the server is down, it won't be able to get replication data.

No Duong, I am testing 22.08.0 version with the same configuration of 6.3.1 version. In 6.3.1 version it showing properly but 22.08.0 its not showing the popup window when we hover on the server.

Can you go to the detail page of that server and check if the "MONITOR DIAGNOSTICS" has information in slave_connections?

Yes, its showing fine on the "MONITOR DIAGNOSTICS" section. Seems in the dash board section popup has some issue?

Hmm, that's odd. From the screenshot, it doesn't have the `master_server_name` attribute. The "popup" relies on that value.

NOTE: In this configuration we have not added any master, we have added all the replicas to schema router, this server main purpose is for only query editor, it means only for the replica servers. But it should show replication status even the configuration doesn't have a master configuration like 6.3.1 version.

The master server must be visible to the monitor. Not necessarily for the service.

@Esa Korhonen, I am not sure it was working fine with 6.3.1 That's why I have raised the issue.

If it was, it was a bug. The monitor cannot labels servers as [Slave] without checking the server they are replicating from (the server could be down, for example). [Master] and [Slave] tag assignment can be customized a bit with the "master_conditions" and "slave_conditions"-settings of MariaDBMonitor.

Close it as it's not a bug on the GUI

Hi Duong,

Is it fixed in the backend?

naresh.chandra@copart.com, do you mean the replication is shown even if it doesn't have the master? I suppose it's fixed in 22.08. As a result, you don't see the replication status when it doesn't have the master.
Or do you want to have it fixed in 6.3?

Duong, If master is not there then its fine in 22.08 version, even slave has master but we are unable to see the replication status whenever we hover mouse on that particular server, you can see the screenshot which i have attached.

So you do have a master configuration on 22.08 and it still doesn't show the replication status? Can you share the configuration file?

I have not mentioned master config, I only configured only slaves in the file.

Without master configuration, the monitor won't be able to generate replication status. As Esa mentioned above, if it worked in 6.3, that was a bug. So the MariaDBMonitor needs to know which master server the slaves are replicating from.

Thanks Duong, for the clarification.
