#### Calculate average queue depth:
`iops_in_progress` will give you an instantaneous value. This will give you the average between polling intervals.
```
SELECT derivative(last("weighted_io_time",1ms))/1000 from "diskio" WHERE time > now() - 30m GROUP BY "host","name",time(60s)
SELECT derivative(last("weighted_io_time",1ms)) from "diskio" WHERE time > now() - 30m GROUP BY "host","name",time(60s)
```
