Is there some configuration item that needs to be enabled? Because it stopped displaying after I upgraded from version 5.4 to 7.5.

| username: 江湖故人 | Original post link

It seems there is no such configuration.

Do you see any abnormal logs on PD?
If not, try switching to another PD. [1]
If that doesn’t work, try restarting the PD nodes one by one.

Isn’t this showing the data from this table? Can you check it?
SELECT * FROM INFORMATION_SCHEMA.CLUSTER_INFO;

Is there any abnormal behavior?

How about displaying it on the central control machine?

Looks pretty normal.

Is there a PD in the host tab?

Did it stop displaying after the upgrade, not a direct installation of 7.5?

Does anyone know if the PD node information on the monitoring page is stored in a table or a configuration file?

| username: dba远航 | Original post link

There should have been an exception during the upgrade.

| username: 江湖故人 | Original post link

Why are there only 2 PD nodes? Take a look at the Region heartbeat report below.

After the upgrade, did you reload the cluster? You can try reloading or restarting it.

Use tiup cluster display <cluster-name> to check the cluster status

| username: 哈喽沃德 | Original post link

The cluster I set up a few days ago was working, and it was also in a 7.5 environment.

| username: Kongdom | Original post link

:thinking: Then it might be due to the upgrade, after all, it spanned two major versions.

  1. Normally, the cluster information page on the Dashboard should include nodes for PD, TiDB, TiKV, and TiFlash (if any). If not, there is definitely an issue.

  2. Upgrading from v5.4 to v7.5 is a significant version leap, and compatibility issues cannot be ruled out. Further investigation and confirmation are needed. The backend running logs for the Dashboard are in pd.log. If the PD node information is not displayed, you should first check pd.log in detail for any anomalies.
