[BUG] Why does "NO DATA" appear in some DNS service monitors?

Is there an existing issue for this?

Current Behavior

It seems that the monitoring job is not running!
It feels like there is a very significant delay in the monitoring job.
It's not just DNS; other services like Prometheus monitoring also frequently show "NO DATA", and it takes a long time before data becomes visible.

We are currently downloading the source code and compiling it ourselves.

The service test can be successful.

I noticed that after the system service is restarted, some service monitoring shows no data. In this case, if I go to the monitoring entry editing interface and click the Confirm button, I can then get data normally after waiting for a while; otherwise, there will be no data at all.
