I don't have any major objections to this format, but to make it easier to understand, could you add a ```Checking changes in node 'xxxxx' - done``` log at the end? So that the above output would become:

```
Checking changes in node 'xxxxx'
-> there was a change in node inventory
-> other change here
Checking changes in node 'xxxxx' - done
Checking changes in node 'yyyyyy'
-> nothing change
Checking changes in node 'yyyyyy' - done
```
