I have tried this method, but it still doesn’t work after deleting the directory and restarting the service.
Have you checked it according to the method in the screenshot?
I tried it. I deployed the cluster using tiup. The cluster configuration file has the monitoring_servers configuration. Then I tried restarting the Prometheus node. After successfully restarting, logging into the dashboard still prompts: The necessary component NgMonitoring is not started in the cluster, some functions will be unavailable.
Added ng_port, please help me check if this configuration is correct.
The configuration is fine, check the ng log to see what error it reports.
Reinstalling version 6.1.0 worked without any issues. Thanks to the technical support lady from PingCAP, and thanks to everyone.
The problem is not solved. Is there an issue with ngMonitor in TiDB 6.5? Why is it OK in version 6.1?
It shouldn’t be an issue with version 6.5. The reason is that I customized the dashboard node in the cluster topology file, but since version 4.0, the dashboard has already been integrated into PD.
May I ask: Is it that custom dashboards are not supported? Or is it because there are anomalies in the format or other aspects of the defined dashboard?
