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

### Is there an existing issue for this?

- [x] I have searched the existing issues

### 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.

### Expected Behavior

_No response_

### Steps To Reproduce

_No response_

### Environment

```markdown
HertzBeat version(s):1.7.3+
```

### Debug logs

_No response_

### Anything else?

_No response_

Start by reproducing the delayed or missing data behavior on HertzBeat 1.7.3+ and inspect the monitoring job and available logs. Compare DNS and Prometheus monitors to determine whether the job is running; done means monitoring data appears reliably without the reported delay.
